Materials: Body, cover, sleeve: Type 316 Annealed Stainless Steel, Ball: 300 Series Annealed Stainless Steel, Cover gland: annealed stainless steel.

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

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

Note: All sour oil and gas valves and fittings supplied without collars and glands unless otherwise specified.

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.
