Welcome to Pinch Valves page.

PendoTECH can offer assistance in process design of pinch
valve(s) integrated to a process. SEE APPLICATION NOTE
FOR SELECTION OF THE PROPER PINCH VALVES.
This includes assistance with interaction with valve manufacturer, with valve selection, and design of hardware
to mount and control the valves and the interface with a control system. Part of the design process includes mounting
them with connectors and optional LEDs that indicate the
valves are energized. Most valve manufacturers offer position feedback sensors that give an output signal to confirm a
valve has physically moved when given an actuation signal. 
Enclosure options include off the shelf ABS plastic enclosures on customized stainless steel enclosures (Figure 1).

The valves can be controlled by a customer's control system or an off-the-shelf device such as a PendoTECH PresssureMAT that has output alarm relays that are switched based on high or low user entered setpoints. PendoTECH can also design a custom control system that can interface and control other devices including pumps, scales, pressure sensors and much more. The pinch valve devices can be tested independently of a control system to ensure proper functioning when they are interfaced together. Samples of devices designed and built by PendoTECH are shown in the figures below.
