Discharge valve for use in Inert fire extinguishing systems. The valve has built-in pneumatic activation for inter-system activation, back pressure activation and mechanical activation interface.

The discharge outlet is connected internally to the Pneumatic Actuator (PA) via a check valve (the check valve allows pressure from the discharge side to enter the actuator side), this allows for the

discharge port to be used as activation port also (back pressure), hence eliminating the need for PA circuitry between valves connected to the same manifold. When more than one manifold is used, the PA system must be connected to at least one IV8 valve on each manifold. The port for the PA function works as both inlet and outlet, hence the same connection is used on both pilot and slave cylinders, and the pilot cylinders can be placed anywhere in the line of IV8 valves. All equipment connected to the PA connection must be rated at 300/400 bar. The standard valve is classified as a Type 2 valve, as it has a built-in burst disc which relieves pressure to the open.
