Magne-Trac Magnetic Level Indicators by Questtec
 |
| Click for larger view. |
The Questtec Solutions Magne-Trac utilizes a non-magnetic pipe chamber mounted directly to a vessel. The process connections from the chamber to the vessel act as an inlet and outlet that allow the liquid level in the pipe chamber to match the level in the process vessel. Inside the chamber, a custom designed float rises
and falls with the level of the liquid in the chamber. A 360 deg. magnet array within the float projects a magnetic field through the pipe chamber to an externally mounted indicator to provide a visual read out of the liquid level within the vessel.For more information about Questtec Solutions products, contact Automatic Controls of Virginia by calling (804) 752-1000 or by visiting their website at https://acva.com.
XOMOX XP3 and XP 4D: The First Soft Seated Plug Valve Meeting the Most Demanding Emissions Standards
The XOMOX XP3
The XOMOX XP3 Sleeved Plug Valves. with patent pending live loaded cartridge seal, are the first valves to pass all four thermal cycles without any packing adjustments, meeting the ISO 15848-1 standard at the BH BH CO3 200C SSA0.
The XP3 still contains the same maintenance-free and cavity-less design benefits of the standard XOMOX® sleeve plug valve, namely no costly lubrication required and no accumulation or contamination of process media.
The XOMOX® XP 4D
The XOMOX® XP 4D Sleeved Plug Valve contains the same live loaded stem cartridge as XP3, while also adding a set of contingency bolting. This additional set of packing allows for a manual override of the seal to atmosphere manual adjustable 4D stem seal of the cover. If there is any emergency failure, this seal can be activated and reduce the need (in the very unlikely case) of any costly unscheduled shutdowns.
XP 4D Features:
- Primary Seal to Atmosphere - Sleeve ensures inline sealing. Manual adjustments are possible.
- Tertiary Seal to Atmosphere Additional 4D Manual - Live loaded cartridge provides improve stem sealing.
- Additional 4D Manual - Manual 4D stem packing for adjustment in case of emergency or excessive assurance.

Industrial Pinch Valve Operation and Performance
A pinch valve offers a cost-effective and practical solution for controlling the flow of media through a pipe line or any other system. The operating principle of pinch valves is simple. In the open position, the valve is full bore with no flow restrictions. During closing, two pinch bars squeeze the valve sleeve shut on the centerline. The sleeve is naturally wear resistant and when particles hit the sleeve’s rubber surface, the energy is absorbed and released when the rubber bounces back.
Pinch valves are controlled through linear motion via a manual screw mechanism, or linear pneumatic or electric actuator.
Heavy duty pinch valves provide bubble tight shut-off even if solids have built up on the sleeve wall. When compressed, any crystallized particles flake-off the sleeve surface. The full bore structure ensures free flow of the medium. The construction and materials of the three main components (sleeve, body and actuator) can be tailored to suit your process conditions.
Pinch valves have gained increased popularity in a wide variety of industries such as waste water treatment, cements, mining, food and beverage, medical, pharmaceuticals, others, primarily because they offer tight shut-off, full bore flow, and pressurized self-cleaning from the movement of the flowing media.
Benefits of pinch valves:
- Long service intervals.
- Only one wearing part.
- Excellent for slurries, dry powders, and abrasive materials.
- Low maintenance cost.
