VICTAULIC S014776001 LOW PRS ACT ASY 776 W/1/2 NPT RESTRICT
Victaulic® FireLock® Low Pressure Actuator, Series: 776, 300 psi, NPT Connection, 1/2 in Connection The Victaulic Series 776 Low Pressure Actuator is a pneumatically actuated valve that is used to trigger the dry, preaction or deluge fire protection system. The Series 776 features a single trip point regardless of supply water pressure. The Series 776 is designed to allow the sprinkler system to operate with a low air or gas pressure of 13 psi/90 kPa, regardless of supply water pressure. The Series 776 is designed to actuate at 7 psi/45 kPa system pressure, thus releasing supply water pressure from the sprinkler control valve diaphragm and actuating the sprinkler control valve in its intended manner. The low system pressure, 13 psi/90 kPa, allows the sprinkler system to have a very low moisture content while the 7 psi/45 kPa trip point will allow water to enter the sprinkler system and reach a greater number of heads more rapidly. The patented design operates as a single actuating device, or when used in conjunction with an electric solenoid, as a pneumatic/electric double interlock valve. The Series 776 Low Pressure Actuator is rated for use on water supplies with up to 300 psi/2065 kPa working pressure. The Series 776 Low Pressure Actuator comes standard on the Series 768 Dry, 769Deluge, and 769 Preaction FireLock NXT™ Valves and is tested and approved to be used in all sizes of Victaulic Series 756 and 758 fire protection valves.
