Potter PCVS-2-CRH (stock no. 1010211) — control valve supervisory switch, double switch, with corrosion-resistant 316 stainless steel hardware.
The PCVS is a weatherproof, tamper-resistant switch that monitors the open position of fire sprinkler control valves of the wall and yard post indicator and butterfly types. It mounts in a 1/2 in. NPT tapped hole in the valve housing and is engaged by the valve indicating assembly or operating mechanism. When the valve moves away from fully open, the spring-loaded trip rod operates two SPDT (Form C) contacts.

Wall and yard post indicator valves and butterfly valves, mounted in a 1/2 in. NPT tapped hole in the valve housing.
What are the contact ratings?
Two SPDT (Form C) contacts rated 10.0 A at 125/250 VAC and 2.0 A at 30 VDC resistive.
How is it tested?
Turn the valve toward closed; the switch must operate within the first two revolutions, stay in alarm while the valve is closed, and restore when the valve is fully open.
