Stop Valves are closed by screwing a rubber gasket down onto a seat in the middle of the valve. Pros only use small versions that act as shutoff valves for fixtures such as sinks and toilets and outdoor sillcocks. Flow is inefficient because of the circuitous route the fluid (water, in most cases) has to follow. It's important to orient the valve in the right direction with the arrow (cast into the side of the valve) aligned with flow direction. That way, water flows against the bottom of the rubber gasket. If the valve is put in backward, the flow will force the gasket away from the top of the valve.

Electric three-way ball valve ball valve three points L and T-type. L-type three-way ball valve for medium flow switching, can make two channels perpendicular to each other; T-type ball valve for medium diversion, confluence or flow switching, T-shaped channel can make the three channels connected to each other or One of the two channels connected, three-way ball valve generally two seat structure, can also be used according to user requirements four seat structure. Structural features and uses 1, compact structure, quick opening and closing, smooth flow, fluid resistance. 2, good sealing performance: the use of PTFE gasket material on all sides to achieve leak-free seal. 3, a multi-purpose valve: any port can be used as an entrance without leakage, tee can be made L-type port can also be made T-port. 4, easy maintenance: After the system pressure relief, without having to remove the entire body can be checked and repaired. 5, Pan suitable for water supply, petrochemical, metallurgy, mining, textile, energy, paper, food, steel and other piping system to switch the flow of media and the diversion of media or mixed fluid.
