Membrane Valve SOCLA 407B is designed for installation that generate significant water hammer. It is 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, on membrane check valves, the opening set 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.
Features Of Membrane Valve Socla 407B :
- Operates in any position
- Low head loss
- Does not generate hammering
- 2 threaded bosses 1/2″ with brass plug
- Closing system : flexible membrane ( thick elastomer disc ) held in its center on a metal seat composed of a grid ( flow equivalent to the nominal section )
- Sealing ensured by membrane’s self-closing.
