Your custom check valve options are virtually endless.

Now available from ISM are a wide selection of standard plastic fittings adapted with check valve cartridge inserts to create valved fittings not found anywhere else. With two styles of cartridges and tens of thousands of fittings, the possibilities are virtually endless.

Spring loaded check valve cartridges are made of nylon or polypropylene with an o-ring seal consisting of Buna-N, Viton, EPDM or Silicone. Cracking pressures range from 3 inches of H2O to 10 psi. These cartridges can be placed in many ISM plastic fittings.

Free floating ball cartridges are made of polypropylene with an EPDM ball. Less than 1 psi is required to open the valve. Normal and reverse flows are available.

Some of the check valves that are available for customization are listed on the Industrial Specialties Manufacturing website.
