Replacement Handwheel for Fuseable Head Fire Valve

DESCRIPTION:

The Screw Cap consists of two parts, an outer section and an inner circular block, which is gripped in the cap with a low melting point solder. When the valve is subjected to a temperature of about 85 deg. C, the solder melts and the inner block is released allowing an integral spring to slam the valve spindle closed, shutting off the oil supply.
