CRANE® Bronze Swing Check Valves: Y Pattern

Check valves must be oriented for flow and gravity effect. The arrow on the side of the
valve indicates the required flow direction.
Before valve installation thoroughly clean and prepare piping system, be sure mating pipe
threads are free from excessive grit, dirt or burrs.
Use pipe sealant on threaded valves, which is recommended for valve, end use.
Use solder on solder joint valves, which is recommended for valve, end use.
Inspect the valve ports and seating surfaces for cleanliness just prior to installation. Take
care to assure that pipe sealant is not excessively applied to the pipe threads, as to foul the
valve seat.
Support the valve to prevent unnecessary stresses induced by the connecting pipe.
