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 SP0735 Series 4 Way valve has three ports in the body and four 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 SP0735 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.
For Female Socket SP0735S VALVE:
The SP0735S VALVE is manufactured utilizing ABS. Utilize a solvent cement made for both PVC and ABS. Cut pipe square.
Chamfer and deburr pipe. Surfaces must be cleaned and free of dirt, moisture, oil and other foreign material. Apply primer to
inside socket surface. Use a scrubbing motion. Repeat applications may be necessary to soften the surface of the socket. Next,
liberally apply primer to the male end of the pipe to the length of the socket depth. Again apply to the socket, without delay,
apply cement to the pipe while the surface is still wet with primer. Next apply cement lightly, but uniformly to the inside of the
socket. Apply a second coat of cement to the pipe, and assemble the pipe into the socket, rotating the pipe 1/4 turn in one
direction as it is slipped to full depth of the socket. The pipe should be held in position for approx. 30 seconds to allow the
connection to “set”. After assembly wipe off excess cement. Full set time is a minimum of 30 minutes at 60 to 100 F. For full cure
see the information on the Solvent cement can.
4.
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, represented with the valve installed on the discharge side of the pump. (Return to the pool)
The SP-735 4-way valve is a multi-functional valve. It allows flow to be directed, controlled, mixed, proportioned or to be shut off
completely.
FUNCTIONS NOTE: When changing flow positions, move handle smoothly and slowly.
1.
Valve allows diversion of flow to or from either Port 1 or Port 2. Ports are color coded and referenced to colors on valve label. When
handle points to "FULL", all flow is thru that port. Optional suction manifold label: SKIMMER is Port 1; MAIN DRAIN is Port 2.
2.
Decreasing flow thru one port is accomplished by varying the handle from "FULL" to "OFF" position.
3.
Valve is closed when handle points to either "OFF" position.
4.
Simultaneous flow (mixing, blending, proportioning) in both port directions is achieved when the handle is in the label regions
between "FULL" and ½/½. At ½/½, flow is equal to (or from from) both Port 1 and Port 2. By turning the handle toward the "FULL"
position of the specific port, the flow increases for that port and decreases at the opposite port. Label is color coordinated to show the
ratio/proportion of flow when throttling is required.
SERVICING
1. Disassembly
a. Place Handle pointer over label referencing "lug" (notch on inside of label).
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. NOTE: The two (2) side holes in Ball face same side of valve as
Handle pointer.
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 either ½/½ position and loosen Assembly Nut halfway.
