Low Pressure O-Ring Type Excess Flow Valves

Check up to five results to perform an action.

Protects pressure gauges and other pressure instrumentation from sudden surges in flow due to operator error or line failure. This valve provides dependable, tight shut-off.

Materials: 316 Stainless Steel: body, cover and sleeve. 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.

Vertical Installation: Since this type of check valve employs a non-spring loaded poppet, valve MUST be installed in VERTICAL position with arrow on valve body pointing UP. (cover gland up).

Resetting Valve: Equalize the pressure across the poppet. The poppet will drop and reset automatically.

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.
