A fire valve having a cooperating valve seat and shiftable valve part. The valve part is carried by a floating valve stem. The first valve includes a piston and cylinder combination which is operatively associated with the valve stem and which causes the valve part to be selectively spaced from the valve seat in response to fluid pressure in the valve.
