Your Valve Automation Experts

Valve Automation Experts

Automatic Controls of Virginia (ACVA) is a provider of valve automation that offers a complete range of services and has facilities that can automate practically any size quarter-turn or linear actuated valve. ACVA can meet even the most complex automated valve requirements, whether you need small ball valves with pneumatic actuators or massive valves, such as those used on municipal pipelines. 

ACVA has a significant competitive advantage over other valve companies in the design, fabrication, assembly, and installation of any valve actuation or automation project. This competitive advantage combines the industry's best pneumatic, electric, and hydraulic valve actuators with its on-premise machine shop and fabrication division. This advantage, along with Automatic Controls' fifty years of expertise, makes them the superior choice as your partner in valve automation.

The technicians at ACVA who work on valve automation are highly knowledgeable in pneumatic rack and pinion and scotch-yoke systems, electric quarter-turn and linear systems, and valve communications. ACVA can handle even the most challenging actuation need, including bus communications, limit switches, fail-safe devices, and solenoid valves.

The Val-Matic American-BFV® Butterfly Valve

The Val-Matic American-BFV® Butterfly Valves are the butterfly valve of choice for shut-off service in water systems. The American-BFV® Butterfly Valve line is designed to provide long life, low headloss and trouble-free performance.

The valve is available in 3 inch to 144 inch Flanged connections, Mechanical joint end connections from 4 inch to 48 inches, and 4 inch to 12 inch Wafer design.

If maintenance becomes necessary, the valve is also designed for easy field service. Adjustment of the resilient seat is easily performed with a torque wrench, as compared to epoxy filled seats that require special equipment and materials or bonded seats that cannot be replaced or adjusted in the field.

Opening and Closing Solutions for the Most Demanding Valve Torque and Thrust Applications

Opening and Closing Solutions for the Most Demanding Valve Torque and Thrust Applications

Every industrial valve requires a mechanism of opening and closing it for the process to continue. Using worm gear actuators, you can operate most quarter-turn butterfly, ball, and plug valves as well as quarter- and multi-turn dampers with your hand's thanks to the mechanical advantage of the worm gear. When an operator opens and closes a valve, the gears provide a mechanical advantage by reducing the required force. When the handwheel changes in size, the torque can be raised or lowered. Worm gear operators that operate manually are relatively affordable, and they require little involvement beyond their position in the production line. 

WEDGEROCK delivers solutions for the most demanding torque and thrust applications by taking a robust approach to the problem. Whether you need to operate valves thousands of meters below the ocean surface or a purpose-made gear operator for your valve line, WedgeRock is the partner you need to provide a solution.

Valves for Municipal Water Distribution, Storage, and Wastewater Treatment

Valves for Municipal Water

Most of the operations in the water and wastewater industries, from treatment to storage, to distribution, rely heavily on pipeline infrastructure. Pipeline infrastructure and dependable control systems are critical to the sector's success. Any systemic flaws or weaknesses could lead to significant losses, dangerous spills, and environmental disasters. 

The safe operation of municipal water systems relies heavily on industrial valves. Among other things, they are in charge of flow management and ensuring the integrity of supply lines. The following is a listing to understand better the performance and applications of the different industrial valves applied in municipal water systems. 

In systems that require precise flow control, globe valves often regulate and control liquid flow. They're also suitable for cutoff, but they're usually more expensive than gate valves. 

The most commonly encountered type of valve is the gate valve. Gate valves are employed to start and stop the flow of liquid. These valves are either completely open or completely closed in reality. These are fantastic shut-off valves. Gate valves come in various forms to suit a wide range of applications. 

Butterfly Valves regulate and stop the flow of water. These valves are small and light, taking up less room than valves that perform equivalent duties. 

A quarter-turn valve used in shutdown applications is a ball valve. The valve uses an embedded ball that spins within the valve body to control fluid flow. Because ball valves are lighter and more compact than gate valves, they are preferred for on-off applications.

In a pipeline system, check valves are responsible for preventing backflow. A check valve opens when fluid travels through a line; however, when the flow reverses, the valve closes. 

High-pressure events or vacuums can harm a pipeline system; thus, the installation of relief valves protect it. The pipeline pressure is not fully released because the valves only release the pressure to a predefined point. Relief valves come in various shapes and sizes to suit a variety of purposes. 

Pinch valves are linear motion valves utilized in piping systems that handle solids, slurries, and thick fluids for throttling and shutdown. A pinch valve uses a pinch tube to control the flow. 

Automatic Controls of Virginia, based in Ashland, Virginia, is a significant distributor of municipal water system valves. 

Automatic Controls assists customers with application, design, product start-up help, product service training, and support and works with some of the most well-known and forward-thinking valve manufacturers on the market today.
