Does it matter which direction a ball valve is installed?
VALVE ORIENTATION: Ball valves may be installed in vertical or horizontal pipe runs, they are bi-directional therefore flow direction is not critical, however the best practice is to set up the valve handle to point in the direction of flow whenever possible.
How does a gas ball valve work?
A ball valve is a shut off valve that controls the flow of a liquid or gas by means of a rotary ball having a bore. By rotating the ball a quarter turn (90 degrees) around its axis, the medium can flow through or is blocked.
Do ball valves fail?
A variety of factors can contribute to ball valve failure including poor design (chemical compatibility, rated pressure/flow rate, etc.), faulty installation, and/or improper operation.
How do you tell if a gas valve is on or off?
Gas shutoff valves When the long side of the nub or handle is parallel to the incoming gas line, it’s open and the gas is flowing. When it’s turned a quarter turn, perpendicular to the incoming pipe, it’s closed.
What does SWP mean on a ball valve?
Working steam pressure (WSP) indicates the maximum steam pressure that a ball valve can withstand at the highest temperature rating. This might also be marked as SWP, meaning steam working pressure.
What is a ball valve in plumbing?
Ball valves, also called shut-off valves, tend to be increasingly found in newer homes. Ball valves use a handle to control the placement of a hollow, perforated sphere in the mechanism. When the handle is turned, the hole immediately opens or closes the water flow.
How do I shut off the gas to my water heater?
