2-Way Relay, Manual Reset Latching Device

A 2-Way, spring-loaded, manual reset latching device, applicable for service on deluge and pre-action valve trims. In its “Ready” position, it prevents draining of the deluge valve’s control chamber, keeping the deluge valve closed. Once the deluge valve is actuated, the RCL 28-2UL shifts to its “Latched Open” position, allowing draining of the control chamber and latching open the deluge valve. Manual resetting is accomplished by rotating the RCL 28-2UL’s knob.
