"In A Pinch" for a Valve That Will Last in Your Toughest Slurry and Abrasive Applications? Flowrox Valve Solutions In Virginia and Washington D.C.

Flowrox Valve Solutions In Virginia and Washington D.C.

Heavy-duty pinch valves from Flowrox are built to last and are ideal for shut-off and control applications involving abrasive or corrosive slurries, powders, or coarse materials. The operation of Flowrox pinch valves is straightforward. The valve is full bore and has no flow restrictions when it is in the open position. Two pinch bars squeeze the valve sleeve shut on the centerline during closing. The sleeve is naturally wear-resistant, and when particles strike the rubber surface of the sleeve, the energy is absorbed and released when the rubber bounces back. Even if solids have accumulated on the sleeve wall, heavy-duty pinch valves provide bubble-tight shut-off. Any crystallized particles flake off the sleeve surface when compressed. The full bore structure ensures that the medium flows freely. 

Flowrox control valves handle the most demanding control applications where conventional valves wear out due to increased turbulence.  When the controlled flow is abrasive, having only one wear-resistant valve part in contact with the medium is significant. Maintenance and spare parts are no longer required. Each valve can be sized and optimized for the best control range, limiting wear and velocity while preventing cavitation in the control valve. Controllability is improved further by using conical sleeves and smart positioners. The Flowrox Control Valve Sizing Program is available to help you with your work. Sizing adheres to the international IEC60534 standard (which is compatible with ANSI/ISA S75). 

Even in the most demanding process conditions, Flowrox slurry knife gate valves isolate flow. The entire valve design maintains the concept of ease of maintenance in mind. Flowrox Slurry Knife Gate Valves evolved from the company's years of experience in providing dependable solutions for abrasive and corrosive process applications.  A load distribution ring prevents over-compression and ensures tight sealing between the sleeve and the valve gate. The load distribution ring is integrated into the valve sleeves to simplify maintenance. The universal tower design of the valve accommodates most actuator types, allowing for actuator interchangeability. In addition, the tower ensures that the top plate, body, and actuator are always aligned and that the gate is in the proper position. The valve body is a one-piece casting, so there is no need for sealing between the body halves.

Pressure and Temperature Switches for Water and Wastewater Treatment

Switches for Water and Wastewater Treatment

Water treatment occurs before the water reaches a business or community, whereas wastewater treatment occurs after the business or community uses the water. 

Water treatment has higher pollution control standards and necessitates more costly treatment procedures such as chemical coagulation and flocculation and the use of granular activated carbon filters. However, contaminant levels are usually low and predictable because most water goes through water treatment from a natural source (such as a river). 

After a business or community uses water, it becomes wastewater and is in most cases returned to the environment after treatment. The treatment standards are typically lower than those used in drinking water facilities. Unlike water treatment, wastewater treatment does not usually take place in a single location. Certain enterprises with highly dirty wastewater must have their treatment system before delivering it to community wastewater treatment plants. 

Temperature and pressure switches apply to many water and wastewater treatment processes at practically every stage. Water flow sensors and switches enable pump vibration control, handle slurry environments, monitor pressure spikes, and endure corrosive media, and address the application difficulties of water and wastewater treatment systems. CCS pressure switches are resilient to pump impulses, pressure spikes, and hammering thanks to Belleville disc spring technology, tight construction, and durable assembly.

Installing a Waterman Cast Iron Sluice Gate Valve Using the Double-Nut Method

This video describes how to install a Waterman cast iron sluice gate valve using the double-nut method.

A sluice gate is a water flow control system. Typically made of wood or metal, they open and close vertically on a frame, allowing water to flow in or out of an area. They're also known as sluice gate valves because of this. A sluice is a manufactured canal or a modified natural stream that conducts water.  This type of gate controls the flow of water and where it goes and is highly beneficial in regulating flooding and managing water levels.

Waterman, a recognized leader in water control products for water treatment, wastewater, high-volume agricultural and rural surface water delivery, hydro-power, and flood control management, manufactures heavy-duty cast iron slide (sluice) gates. You'll find Waterman gates in applications where safety, longevity, and reliable performance are essential, such as dams, tidal environments, water treatment plants.

Trace Mechanism or Snap-Action - What's in Your Pressure Switch?

Complex systems and processes can use either a trace or a snap-action switch to provide an electrical response to the rise or fall in pressure or temperature. System pressures and temperatures rarely follow a smooth pattern of rising and falling. The switches used to track and control the system are subject to those fluctuations, as illustrated in the following graph.

Deciding whether to use a snap-action design is critical to your switch's efficiency, accuracy, and longevity. This video will cover key differences between each device and how they apply to the switch operation. 

What is the difference between a trace switch and a snap-action switch? 

In their simplest form, pressure switches have two components: a mechanism that reacts to a change in pressure and an electrical switch (sometimes called a micro-switch). When the pressure or temperature reaches a certain level (the set-point), the mechanism moves to actuate the switch. This process can either allow or stop currents in the control circuit.

What is a Trace Mechanism?

Common alternative mechanisms to snap-action devices are trace designs, also known as spring-based mechanisms. Switches with a trace mechanism follow or trace the exact pattern of pressure or temperature changes. These trace devices can include a helical spring or spiral spring, a Bourdon tube, or bellows in their mechanism. 

A spring-based trace switch mimics the pattern of changes even after reaching set-point. The mechanism and micro-switch are in constant motion when there are changes in pressure in the system. This continual movement wears on the components of the instrument and electrical switch. And over time, it causes the set-point to drift from the original setting to fatigue and the mechanism's failure. 

What is a Snap-action Mechanism?

Unlike trace switches, a snap-action mechanism remains inactive during system pressure and temperature changes. Upon reaching the set-point, the snap-acting disc immediately reacts to activate the switch. Eliminating this continuous motion until the point of activation and deactivation can reduce the mechanism and switch element wear, extending its duration. 

Snap-action designs are the premium type of switch on the market. They can perform 10 million cycles or more due to the components' low fatigue, including the micro-switch. 

While trace and snap-action pressure and temperature switches may perform the same function, understanding the difference in their movement and precision explains why quality-minded people prefer snap-action controls over other designs. Trace designs fatigue the mechanism and the internal micro-switch through constant motion. Snap-action switches use an innovative snap-action disc spring that remains still despite fluctuations until action is needed. 

CCS pioneered the Dual-Snap, snap-action disc used to provide accurate and reliable pressure and temperature measurement under every operation. For more information on CCS pressure and temperature switches in Virginia, contact Automatic Controls of Virginia.

Valves for Hydropower

Valves for Hydropower

One way of producing electricity is through hydropower, which is installing dams on rivers that have a large drop in elevation—the dam stores lots of water behind it in a reservoir. Near the bottom of the dam wall, there is a water intake. Gravity causes it to fall through a penstock inside the dam. At the end of the penstock, a turbine propellor turns by the moving water. The shaft from the turbine goes up into the generator, which produces the power. Power lines connect the generator to the electric distribution system.

Electricity demand is not constant. Requirements go up and down during the day. Overnight there is less need for electricity in homes, businesses, and other facilities. Hydroelectric plants are more efficient at providing peak power demands during short periods than fossil-fuel and nuclear power plants. One way of doing that is by using "pumped storage", which reuses the same water more than once.

Pumped storage is a method of keeping water in reserve for peak period power demands by pumping water that has already flowed through the turbines back up a reservoir above the power plant when customer demand for energy is low, such as during the middle of the night. The water is then allowed to flow back through the turbine-generators when demand is high and the system is under heavy load.

The reservoir acts much like a battery, storing power in the water when demands are low and producing maximum power during daily and seasonal peak periods. An advantage of pumped storage is that hydroelectric generating units can start up quickly and make rapid output adjustments.

The Hydro/Dam Industry demands can take a toll on valves not up to the job of using the power of moving waters to generate electricity. Val-Matic has several Quarter-Turn and Check Valves that can meet these demands. Quarter-Turn valves such as QuadroSphere® Ball Valves, Ener•G® Ball Valves, and American-BFV® Butterfly Valves are available in a wide range of sizes and pressure classes. The QuadroSphere® has additional flow paths and a seat that is contact minimized for reduced wear and operating torques. Val-Matic's Surgebuster® Check Valve, Tilted Disc® Check Valve, and Swing Check Valve have features and designs to prevent slamming, reduce headloss and provide significant pumping cost savings.
