Detailed Product Description

C35 Back Pressure Valve enables efficient air removal through the Air Eliminator in a pump operated metering system.


  • Rugged construction.
  • Self actuated spring loaded design.
  • Bubble tight shut-off.
  • Suitable for a wide range of liquids viscosities.


TheBack Pressure Valve is always fitted downstream of the Flow Meter. Itconsists of a housing with a spring loaded valve having a soft seal.The valve is designed to remain open on a pre-determined systemoperating pressure without providing any resistance to liquid flow. Ina typical liquid metering system using a centrifugal pump, air can getsucked into the system, especially towards the end of the delivery,when the liquid supply tank is about to get empty.

Due to the presence of air in the pump, the system pressure falls down& when this fall in pressure becomes less than the set pressure ofthe Back Pressure Valve, it starts to close. This forces the air toescape through the Air Eliminator to ensure metering accuracy. As soonas the liquid supply is restored, the Back Pressure Valve automaticallyopens fully to enable normal metering operation.
