The V250 Electric / Pneumatic Control Head offers two methods to actuate the Amerex Dry Chemical System. One method is to manually discharge the system using pressure from a
Nitrogen Cylinder of a remote Manual Actuator through the Pneumatic Actuation Network.
The second method is to discharge the system with use of an electrically actuated Linear
Actuator. The Electric / Pneumatic Control Head is constructed of extruded brass and threads directly on the top of the Agent Cylinder Valve. When supplied with nitrogen pressure from
the Pneumatic Actuation Network through 1/4” NPT female ports on either side, the piston inside the V250 Electric / Pneumatic Control Head extends and depresses the Schrader valve
in the Agent Cylinder Valve, releasing the Dry Chemical Agent. The top of the V250 Electric /
Pneumatic Control Head has a threaded hole that accepts a Linear Actuator (P/N 22579 or
20500). The Linear Actuator, when activated, will force the piston inside the V250 Electric /
Pneumatic Control Head down, releasing the Dry Chemical Agent.
