ABSTRACT:
The condition responsive valve construction has a valve seat disposed between a pair of ports to interconnect the same together and has a valve member for opening and closing the valve seat in response to a condition sensed thereby, a by-pass passage being provided in the valve member for fluidly interconnecting the ports together event though the valve seat is closed by the valve member. The by-pass passage has a check valve therein to permit fluid flow through the by-pass passage in only one direction. The valve construction has a restrictor unit fluidly interconnecting the ports together even though the valve seat is closed by the valve member and the by-pass passage is closed by the check valve.
