Pneumatic wafer type soft seal butterfly valve

Pneumatic wafer type soft seal butterfly valve is composed of single-acting or double-acting pneumatic piston actuator and butterfly valve. Powered by compressed air,

  Pneumatic wafer type soft seal butterfly valve is composed of single-acting or double-acting pneumatic piston actuator and butterfly valve. Powered by compressed air,

  The valve stem drives the valve core to rotate 90 ° in the valve body to realize the action of fully open and fully closed. The actuator can also be equipped with travel limit switch,

  Three pieces of solenoid valve and air source. Pneumatic butterfly valves are not only widely used in general industries such as oil, gas, chemical, water treatment, etc.

  And also used in the cooling water system of thermal power stations.

  The main technical parameters:

  Power source: dry or lubricated air, non-corrosive gas, oil, impurity particles in the medium <30μm;

  Air source pressure: minimum air source pressure 2.5Bar, maximum air source pressure 10Bar;

  Drive mode: pneumatic, manual

  Working temperature: -20 ℃ ~ + 80 ℃; -40 ℃ ~ + 180 ℃;

  Air supply pressure: 0.4-0.7MPa;

  Single-acting actuator: air-closed type-valve position open (FO) when degassed; air-opened type-valve position close (FC) when degassed

  Double-acting actuator: ventilation is required for both opening and closing, and the lost gas valve remains in place.

  Nominal pressure: PN6, 10, 16bar

  Protection grade: IP55, IP65, IP67

  Valve body material: cast iron, carbon steel, stainless steel

  Sealing surface material: nitrile rubber (X), polytetrafluoroethylene (F), fully lined polytetrafluoroethylene (F46)

  Can be equipped with accessories: solenoid valve, air source triplet, limit switch, positioner, handwheel
