Pneumatic Air Control Valve

Pneumatic Air Control Valve which controls the ratio of fuel to air in the intake manifold of the engine includes a valve assembly which is operative in response to the combined action of the negative pressure existing in the intake manifold and positive pressure from an air pump operated by the engine.

Series - 150 To 600

When the sum of the negative and positive pressures acting on opposite sides of a diaphragm are sufficient to overcome a spring force on the negative pressure side of the diaphragm the movement of the diaphragm will cause the operation of the valve to admit atmospheric air pressure either directly into the intake manifold or to a fuel regulating device to operate a further valve to reduce the supply of fuel to the carburetor.

Design Features
  • It is a right-angle rotation structure, which is composed of V-shaped valve body, pneumatic actuator, positioner and other accessories. There is a natural flow characteristic of approximately equal ratio; Double bearing structure, small starting torque, better sensitivity and induction speed; Super shear ability
  • The purpose and characteristics of the pneumatic control valve is a right Angle rotation structure, it and the valve positioner matching use, can achieve proportional adjustment; V-type spool is most suitable for various adjustment occasions, with large rated flow coefficient, adjustable ratio, good sealing effect, sensitive adjustment performance, small volume, vertical horizontal installation
