Dry pilot actuator is an auxiliary releasing device designed for use with specific deluge valve and preaction valve having dry pilot release systems, or preaction valve having double-interlock electric/pneumatic release.
In the case of dry pilot actuation, air pressure is released due to opening of a pilot sprinkler. Or in the case of double-interlock preaction systems air pressure is released from the system piping due to the opening of an automatic sprinkler. When the dry pilot actuator works, it permits water pressure to be released from the deluge or preaction valve differential chamber, thereby allowing the deluge or preaction valve to open.
