Membrane check valves – 327 irrigation, limited working pressure
Detail Product :
PRESSURE PFA/PS in bar θ 60°
NIPPLE : GJL cast iron epoxy coated
STRAINER : galvanised steel
MEMBRANE : EPDM
OPTIONS : stainless steel (316L) strainer
Mounting with flexible hoses
Application and Special Features :
- Operates in any position
- Low head loss
- Does not generate hammering
- Closing System : EPDM tubular membrane collapsing towards the center of strainer at the inteka
- Sealling guaranteed by the flexible membrane against the machined internal part of the casing
- On membrane check valves, the opening regulated by the elasticity and the thickness of the membrane is very proggressive 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
