“RC” make screwed end ball valve can be installed in any orientation, ball valve without strainer are bi-directional, where as ball valve with strainer should be installed as per flow of the direction mark on the valve body. The valve steam orientation is not critical.
Installation Steps
- Inspect the ball valve ports, seating surfaces and threads to ensure they are clean and free of foreign debris.
- Operate the valve from fully open to fully closed position.
- Ensure the threaded pipe connections to be threaded into the valve are accurately threaded to the right dimensions, clean and free of foreign material, metal shavings or burrs.
- Apply a high-quality pipe thread sealing compound or P.T.F.E. thread sealing tape
- Valve and piping must be in alignment to prevent cross-threading, the male threaded fittings needs to be aligned with the axis of the tapped hole .Maintaining proper pipe alignment during assembly eliminates unnecessary stresses on the valve body. Support the valve and piping in alignment to prevent any unnecessary stresses on the valve body by connection the pipe. Pipe supports must be capable of keeping the pipe in alignment and bearing the weight of the fittings, valves, pipe and its contents
Note:- failure to properly support piping will void warranty and could result in structural damage. - When installing two- piece body ball valve always use two wrenches when making up pipe joints to these valves. Position one wrench on the valve and closest to the pipe joint being tightened and the other wrench onto the pipe to prevent transmitting torque through the valve body joint, between the valve body and tailpiece. This also prevents distortion of the internal parts of the valve.
Note:- Failure to follow this instruction will stress the body joint and may result in the leaking at the body joint.
- Tighten until you can feel the joint starting to seat the fitting is almost pointing in the desired direction. Then increase the tightening force a little if each attempt gives less movement, continue to tighten until you have proper alignment and you should have a sound joint. If the movement stops suddenly have probably bottomed out against the stop in the valve body.
Note:-never back off a connection to achieve proper alignment. loosening valve, pipe and fitting connection will compromise the integrity of the seal and contribute to leakage and failure.
Warning:- Do not over tighten the valve onto the pipe, as it is possible to distort the internal parts of the valve or break the valve body or parts or cause a stress fracture in the valve body
