Kidde Discharge Head Plain Nut (872450)

FSP Can Supply Kidde Discharge Head Plain Nut (872450) The plain nut discharge head attaches to the discharge valve on the Kidde High Pressure Carbon Dioxide (HP CO2) cylinder assembly.

The discharge head operates the discharge valve using CO2 pressure to open the discharge valve. Pressure may be applied from the cylinder, when fitting a control head to the discharge valve, or applied from the manifold connection.

This feature allows the plain nut discharge head to be fitted to either a master cylinder(s), which are fitted with a control head, or each of the remaining manifold cylinders. Additionally, this feature simplifies installation and periodic service as no additional actuation hose/tubing is required between each cylinder.

The discharge head also features a metal to metal check, which eliminates the need for a separate check valve at each manifold connection.

A discharge flex hose connects the discharge head to the system manifold. Alternatively, a swivel adapter may be used in place of a discharge flex hose to connect to the system manifold. A discharge head needs to be ordered for each cylinder assembly.

Each CO2 cylinder and valve assembly must be equipped with a Discharge Head at installation to actuate the cylinder valve. The Discharge Head is assembled to the top of the cylinder valve and contains a spring-loaded piston, which, when actuated by CO2 pressure, is designed to depress the main check in the valve and discharge the contents of the cylinder.

The piston provides the necessary mechanical advantage to open the main check on the valve. The transfer outlet is designed to mate with the swivel adapter on the 1/2-inch and 3/4-inch Flexible Discharge Hoses (P/Ns 252184 and 251821 respectively).

The Discharge Head also contains an integral Stop Check whose function is to automatically prevent the loss when the I-Valve is actuated by a control head. Pressure entering the outlet will not actuate the cylinder.

Pressure actuation is isolated only to that single cylinder. The Plain-Nut Discharge Head offers two means of actuation: the contents of the cylinder can be discharged by pressure entering the outlet from the pressure in the manifold being discharged from a master cylinder, or, when the I-Valve is actuated by a control head.

The Plain-Nut Discharge Head is used on each cylinder of a multiple-cylinder system.
