Waukesha Cherry-Burrell Mix Proof valves meet
design, and style.
W75RS PMO Mix Proof valves are double seat shutoff valves for separating
different media. The valves are equipped with a drain/vent for the space between
the seats equal in size to the largest port into the valve body. The seats are tended
by stems equipped with electrical switches capable of signaling whether the
upper and/or lower seat is in the proper location. W75RS PMO valves are air-
operated (air-to-raise).
Each Waukesha Cherry-Burrell valve is shipped completely assembled,
lubricated, and ready for use.
