The standard electromechanical actuator types are AUMA Norm SA-series and Rotork IQ-series actuators equipped with build-in limit switches and manual handwheel. The standard voltage is 380V 50Hz, others on request. 

Technical specifications

Size range: 15~2000mm, ½~84in

Pressure range: 1-10MPa, 1:2 safety factor, which means bursting pressure is 2 times higher than the operating pressure.

Material of valve body

DN15~200 (carbon steel, ductile iron, aluminum alloy, stainless steel-casting process)

DN250~2000 (45#steel, stainless steel welding technology )

Material of valve sleeve: NR, EPDM, CR(chloroprene rubber), NBR, butyl rubber, FPM, Hypalon rubber.

Working status of pinch valve
Fully-open: the full-bore elastic valve sleeve of pinch valve without any gaps & dead spots.

Center closed: closed on the center line of the valve body, which avoids turbulence and abrasion, as a result, the valve sleeve becomes a smooth and enclosed venturi with self-cleaning during every operation.

Fully-closed: it ensures the pinch valve is with no leakage of two ways when shut off, and the safe design of inner valve sleeve requires no maintenance of sealing elements.

Automation of control valve

Pneumatic (double-acting, single-acting, adjusting, manual actuators)

Electric (switch type, adjusting type, linear type)

Hydraulic

Manual (handwheel, turbine)
