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.
Open Pinch Valve
The open body construction is designed for applications with relatively low pressures and low temperatures when the flowing medium is non-hazardous. The open body construction is light and it is very easy to access for service.
The available valve diameters begin with 80 mm. The standard body material is mild steel, but AISI316 bodies can also be delivered upon request.
The open body features with the advantage of being able to tolerate misalignment and vibration.
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.
