Turbine Pinch Valve

Applicable material: aluminium, cast iron, stainless steel etc. Applicable size: DN25 to DN300 Applicable pressure: Low Pressure Applicable temperature:80 Design standard can according to ANSI BS JIS DIN,etc. Crate

A pinch valve is a full bore or fully ported type of control valve which uses a pinching effect to obstruct fluid flow.

Type 1: Turbine The large diameter manual valves and the valves used in high pressure applications come equipped with a reduction gear to ease the operation. Manual valves can also be fitted with a chain wheel and extended stem. Type 2: Electric actuator ELECTROMECHANICAL ACTUATORS (E) 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. Type 3: Electromechanical actuator Electric linear actuator Electromechanical actuator with electronic positioner (EO) The standard actuators are Auma Norm SA-series with RWG, Auma Matic SAM series or Rotork IQ-series. The standard incoming signal for the electromechanical positioner is 4-20 mA. All electromechanical actuators are supplied complete with manual override. Type 4: Pneumatic actuators WIDE VARIETY OF PNEUMATIC ACTUATORS (A) The pneumatic actuator is a double acting cylinder. The standard supply pressure for the pneumatic cylinder is min. 6 bar. The cylinder size is determined according to the process line pressure. The pneumatic actuator is also available in special materials for aggressive conditions.

Technical Specifications Advantages of Woke Pinch Valve Woke pinch valve has smooth media and minimal frictional resistance without any leakage nor blockage. It is highlighted in its long service life, easy maintenance, and favorable price.

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, ~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.

Factories around the world that have the ability to design and manufacture large size pinch valve is very few, for example: Red Valve, FLOWROX, Jindex, and etc. As the core part of pinch valve, the rubber valve sleeve has high requirements on the manufacturing capability of the suppliers with the size increase of pinch valve. It requires not only large-scale rubber processing and vulcanization equipment, but also a mature and reliable manufacturing process of valve sleeve, which is the basis for manufacturing large-size pinch valves. We, FENGCHI , have these basic conditions to design and manufacture DN600-DN2000 large-size pinch valves maturely.

Friendly and cost effective frame pinch valves that do not compromise on good quality. We ensure that our pinch valves are manufactured to suit various applications. Valve sizes are available from 50mm to 350mm. Larger sizes are available on request. Pinch valves all over the world operate on the same principal and are manufactured with heavy material, therefore making them cumbersome to handle. Frame Pinch Valves are Built with Cost-Saving in Mind Frame pinch valves differ from the norm in the sense that they are built from lightweight materials, however, the design takes care of the body strength, and the same principal applies for the wear sleeve. Lighter built valves require less installation effort in difficult applications, less bracketing on piping, and less transport costs.

Air operated pinch valve Without actuators, cost-effective automated control valve, applicable for various kinds of demanding applications. Technical specifications Size range: 15~2000mm, -84in Actuating mode: air or liquid Operating differential pressure: 2bar Applicable Media: Powder, Slurry, Particles
