Resilient Gate Valve for Underground 1025
Most of the 2.5 inch butterfly valveused in the walkway begin to be made of ductile cast iron, as copper or stainless steel becomes much more expensive. The number ofbutterfly valvesused in the 2.5 inch small bore pipe will be more becausebutterfly valvesare light in structure, open and close quickly and have low flow resistance. The opening and closing of the valve rely on the rotating handle to drive the stem, which makes the disc produce 90 degrees of rotary motion. The valve is closed when the handle is pulled clockwise or the hand wheel is turned. Otherwise open.Low price towafer butterfly valves, very adaptable to installation controls.
However, the wafer butterfly valve should not be used at the end of the pipeline and downstream where disassembly is required, because when the downstream flange is disassembled, the clamping valve will fall off, in which case it is necessary to make another short connection for disassembly. The wafer butterfly valve has small operating torque, and the switch is light and convenient. The flow characteristic tends to the straight line, and the regulating performance is good. Its open and close test times up to 10,000 times, long service life; It has good sealing performance and the leakage of gas test is zero. The wafer butterfly valve is made of a variety of parts, which can be used in the pipeline of fresh water, sewage, sea water, steam, natural gas, food, medicine, oil, and various acid and alkali medium.
