Item # SW06600, Low Pressure O-Ring Check Valves




Provide unidirectional flow and tight shut-off for liquids and gases with high reliability. When differential drops below cracking pressure*, valve shuts off. (Not for use as relief valve.)

Materials: 316 Stainless Steel: body, cover, poppet and cover gland. 300 Series Stainless Steel: spring Standard O-ring: Viton, for operation to 500° F (260°C). Buna-N or Teflon available for 250°F (121°C) or 400°F (204°C) respectively; specify when ordering.

*Cracking Pressure: 20 psi (1.38 bar) ±30%. Springs for higher cracking pressures (up to 100 psi (6.89bar)) available on special order for O-ring style check valves only.

Minimum operating temperature for standard o-ring check valves 0°F (17.8°C).
For low temperature option to -423°F (-252°C) add suffix LTTO (Low temperature spring & Teflon o-ring).

Caution: While testing has shown O-Rings to provide satisfactory service life, both cyclic and shelf life may vary widely with differing service conditions, properties of reactants, pressure and temperature cycling and age of the O-ring. FREQUENT INSPECTIONS SHOULD BE MADE to detect any deterioration, and O-rings replaced as required.

Caution: See Tubing section for proper selection of tubing.
Note: For optional material see Technical Information.

Note: All check valves are furnished complete with connection components unless otherwise specified.
