3/16" Hose Barb Diaphragm Check Valve, EPDM Diaphragm, Natural & Black Nylon Body

A highly reliable, normally open 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.

  • Cracking pressure: 0.5 psig maximum
  • Flow rate: 6.4 CFH (0.1 CFM) at 0.4 psig maximum*
  • 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:

Nylon 66 is a strong, stiff engineering plastic that provides excellent resistance to chemicals and hydrocarbons. This includes oils, lubricants and hydrocarbons such as gasoline, kerosene and diesel fuel.

EPDM rubber diaphragms have an excellent operating temperature range. They also have excellent resistance to water and steam, alkali, mild acidic and oxygenated solvents, ozone, brake fluids and phosphate ester-based hydraulic fluids. EPDM has an excellent resistance to aging.

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