The patent-pending Victaulic series 768 FireLock NXT™ dry valve is a low differential, latched clapper valve that uses a unique direct acting diaphragm to separate system water supplies from dry-pipe sprinkler systems.

• The low differential, unique latch and actuator design of the valve allows the valve to be reset without opening the valve
• The low differential design is not subject to water columns
• The valve allows the water to operate a water motor alarm and/or electric pressure alarms, which continue until the flow of water stops
• With the optional accelerator, the valve can be configured to respond faster for use in larger systems, or where faster response times are required
• The valve is rated to 300 PSI/2065 KPA water working pressure and is factory tested hydrostatically to 600 PSI/4135 KPA for sizes 1-1/2 - 8 IN/40 - 200 MM
• VDS trim configurations are approved to 16 BAR
• Required air pressure for all trim variations is 13 PSI/90 KPA
• The Victaulic series 768 FireLock NXT™ dry valve is made of high-strength, low-weight ductile iron, and it offers easy access to all internal parts
• All internal parts are replaceable
• Maintenance and service can be performed without removing the valve from its installed position
• The rubber clapper seal is replaced easily without removing the clapper from the valve
• The valve is painted inside and out to increase corrosion resistance
