SOCLA TYPE 407


Membrane check valves – 407 boosting units, vacuum pumps, compressed air

Description :

These valves are designed for intallations that generate significant water hammer. They are very reliable and quiet (no mechanical moving parts, anti-incrustation closing system and seat). Ideal for booster pumps, sprinkler systems, motor or electric pump units and compressed air circuits. Alternating operation.

  • Operates in any position
  • Low had loss
  • Does not generate hammering
  • Closing systems : flexible membrane (thick elastomer disc) held in its center on a metal sat consisting of a grid (flow equivalent to the minimal selection)
  • Sealing ensured by self-closing membrane
  • On membrane chck valves, the opening regulated by the elasticity and the thickness of the membrane is very progressive and can be obtained as a result of a few centimeters of W/C. Because of this, this check valve is particularly suitable for variable flow pumps and pulsatory operation
