A lockout valve is a manually operated valve installed between the agent manifold and the discharge pipe to the protected area. Lockout valves are normally open, but can be locked in the closed position when maintenance is under way. This prevents agent from discharging into the protected area for the safety of the maintenance personnel. The lockout valve shall be installed at the end of the agent manifold or, if a common manifold protects multiple hazards, downstream of each selector valve.
Lockout valve assemblies include a high visibility indicator and weatherproof limit switch. The limit switch shall initiate a “Trouble” signal at the control panel when the valve is in the closed position. All valves have a maximum pressure rating of 70 bar (1015 PSI). When using lockout valves, also install a pressure relief valve wherever pressure could be trapped in closed sections of pipe.
The lockout valves are available in sizes 1, 1 1/2, 2, 3, and 4 inches. Lockout valve sizes 1, 1 1/2, and 2 in. have NPT threaded inlet and outlet ports for connection to the distribution piping. Lockout valve sizes 3 and 4 in. use grooved fitting to connect to the system piping. When installing, choose the correct mating fittings to match with the groove fitting of the lockout valves.
