3/8" Triple Hose Barb Diaphragm Check, Viton™ Diaphragm, Natural Kynar® Body

A highly reliable diaphragm check valve that can be installed in any position. This allows the greatest flexibility when you need backflow protection for a vacuum, gas or liquid system.

The free-floating diaphragm reacts to the slightest difference in pressure across the valve giving it a very rapid response time between free-flow and no-flow conditions.

Manufactured by MPC Novares. ISM is a partner supplier of MPC high quality, automotive grade OEM diaphragm check valves.

  • Flow rate: 840 CFH (4.1 CFM) minimum at 6.9 psig*
  • Sealing pressure: 3 psig back pressure required for a tight seal

*CFH is cubic feet per hour and CFM is cubic feet per minute.

Materials:

Kynar® (PVDF) is a mechanically strong, high purity engineering thermoplastic with excellent chemical, abrasion, flame and weather resistance plus it has low gas permeability. PVDF has excellent chemical resistance and is particularly resistant to inorganic and organic acids, hydrocarbons and halogenated solvents. It is highly resistant to wet or dry chlorine, bromine and other halogens, most strong acids, aliphatics, aromatics, alcohols and chlorinated solvents.

Viton™ (FKM or FPM) rubber diaphragms have an excellent operating temperature range. FKM is also resistant to a wide range of chemicals including ozone, mineral oils and greases, aliphatic (non-aromatic), aromatic and chlorinated hydrocarbons, gasoline, diesel fuels, silicone oils and grease. It also has excellent resistance to oxidation aging.

We recommend checking chemical compatibility and requesting samples for testing in real operating conditions.
