Testing Procedure	N/A Every valve is tested for bubble tight shutoff prior to leaving the factory. Pressure testing preformed on Polyvinyl Chloride (PVC)/Ethylene Propylene Diene Monomer (EPDM) valves at 73 ºF water temperature, non-shock.
Additional Information	N/A 10"-24" valves shall have epoxy coated gear actuators with handwheel. 8" valves shall be either spring lever or gear actuated as required or specified. Seat liners shall be full faced with integral, ribbed flanges. No auxiliary gaskets shall be required for installation. Seat liners shall effectively isolate the body and shaft from the flow media. Seat liners shall also thermally insulate the body from the internal operating temperature. Valve liner and seals are replaceable.
