Silent Check Valves

In these valves, the water flow pushes the valve disc back and water flows around the disc. These valves are recommended for use in pumping stations and pump houses.

  • Valve specifications:
    • Excellent mechanical resistance to impact and pressure
    • Very low pressure drop
    • Long life due to the use of stainless steel axle, spring and sealing ring
    • Preventing shock in the pumping system during a sudden power outage or reversal of water flow direction, due to the presence of a stainless steel spring behind the disc and rapid valve closure
    • Back-to-back installation capability with butterfly valves
  • Advantages of Valvepi check valves over other check valves
    • In these valves, the water flow pushes the valve disc back and water flows around the disc. It is recommended to use these valves in pumping stations and pump houses because after the water flow is cut off, the valve disc closes in a very short time, less than a second. Also, behind the disc of these valves is a stainless steel spring that helps the valve close faster.
  • Paint coating: All cast iron parts are coated with blue epoxy powder paint RAL5005 or RAL5015 with a minimum thickness of 250 microns and with an electrostatic spraying mechanism, in accordance with DIN 30667 standard.
