JEC Pumps (www.jecpumps.com) has announced that its Pneumatic Pinch Valve range features center pinch action, with pneumatic cylinder type actuators operating the pinch bars. Offered in automatic, regulating control or simple on-off type, the PPV are specifically designed for use in harsh slurry, highly abrasive flow control applications.
Ensuring positive close shut-off, the flexible elastometer sleeves eliminate the need for gaskets while providing for easy leak tight installation among the process piper flanges. In addition, the simple open-close function pinch valve is mounted with solenoid valve and pneumatic actuator. Instead of using solenoid valve, the control pinch valve employs electro-pneumatic valve positioner. The pinch valves in the SAPV range are mounted by compatible smart positioner and equipped with a digital display.
Meanwhile, the company’s DPV range of pinch valve can be operated both by manual hand wheel and pneumatically. These dual operated pinch valves are equipped with a normal hand wheel operation on one side and with pneumatic actuation on the other.
Aside from the actuation accessories, the pneumatic pinch valves features a smart position transmitter for easy operation from a remote location. Calibrating the special sensor switch with a pneumatic actuator allows the valve to be operated from a PLC station. Automatic Pinch valves are also offered with multi-turn motorized electrical actuators.
The pinch valve’s elastometer sleeve is made of a flexible rubber hose that are molded with special reinforcements for challenging applications.
