Body	MSS SP-81 requires the valve body (pressure vessel and related structure) to designed for and hydrostatically pressure tested to 1.5 times the rated working pressure Valve rated pressure – 150 psi Body test pressure – 225 psi
Gate	MSS SP-81 requires the gate to be designed for and hydrostatically pressure tested to 1.1 times the rated working pressure Valve rated pressure – 225 psi Gate test pressure – 165 psi
Seat	MSS SP 81 has an allowable leakage rate (for metal to metal seated valves) of 40 cc per inch of diameter, per minute at 40 psi pressure. On a 12” valves this would be equal 40 times 12, or 480 cc per minute at 40 psi. Maximum allowable leakage of 0.6 GPM when tested with water at 40 psi applied in the normal flow direction. No visible leakage when tested with water at 40 psi (For Soft seated valves only)
Face To Face	MSS-SP-81 has specified face-to-face dimension and tolerance of each valve size to assure ease of installation for the consumer, regardless of the valve manufacturer. See catalogue for dimension.
