This valve is rated for swimming pool or spa service to 50 PSI maximum at
water temperatures not to exceed 150 °F
VALVE INSTALLATION
1.
The SP0730 Series 3 Way valve has three ports in the body and two ports in the ball. The two side ports are directional, and the
third port is common. The common port (3) can be connected to either the suction or discharge line of the system.
2.
For Female Threaded SP0730 VALVE:
Wrap threads of the 1 ½” pipe with Teflon tape of 3 to 3-1/2 mil thickness. The tape should be wrapped in a clockwise direction
starting at the first or second full thread. Overlap each wrap by, 1/2 the width of the tape. The wrap should be applied with
sufficient tension to allow the threads of a single wrapped area to show through without cutting the tape. The wrap should
continue for the full effective length of the thread. To provide a leak proof joint, the fitting should be threaded into the pipe
“hand tight”. Using a strap wrench only. (Never use a stillson type wrench) tighten the joint an additional 1/2 to 1-1/2 turns past
hand tight. Tightening beyond this point may induce excessive stress that could cause failure.
3.
After making connections, hand tighten the Assembly Nut. This will ensure proper seating and alignment of ball. DO NOT
OVERTIGHTEN.
VALVE OPERATION:
The above diagrams of flow variations. (Return to the pool)
The SP0730 3-way valve is a multi-functional valve. It allows flow to be directed, or to be shut off completely.
SERVICING
1. Disassembly
a. Place Handle pointer in “CLOSED” position.
b. Disengage Assembly Nut and remove End Connector and 0-Ring from valve body.
c. Remove Ball from valve body. IMPORTANT — Note position of Ball relative to handle pointer. Valve must be assembled with
same Ball/Handle relationship to ensure proper operation.
d. Remove Handle by exerting a strong upward pull. Note the position of groove on stem.
e. Press Stem DOWN into valve body and remove.
f. Inspect O-rings, Seats and Ball for cuts, scoring or wear, and replace as necessary.
g. The Ball Seats are easily removed by prying out of recesses. Be careful not to nick or damage them.
2. Assembly
a. Lightly lubricate O-rings with silicon or light oil to make assembly easier. Be sure all Seals are clean and firmly in place.
b. Assemble in reverse order of disassembly ensuring Ball and Handle are properly positioned.
WINTERIZING
Drain all liquid from line and valve. Place valve in any open position and loosen Assembly Nut halfway.
