J41X-16Q is a kind of ductile ironFlange shut-off valvesJ41X-16Q valve is a forced sealing type valve. When the valve is closed, pressure must be applied to the valve flap in order to force the sealing surface not to leak.J41X-16Q valve media flow is usually used in a top-down manner, so that under media pressure, the force to close the valve is small, while the force to open the valve is large, and the diameter of the valve stem can be reduced accordingly, and at the same time this form of valve is also more tightly. Widely used in tap water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, shipping, metallurgy, energy systems and other fluid pipelines as a connection and cut-off device to use.
Product Parameters
- Simple structure, relatively easy to manufacture and maintain.
- Small working stroke, short opening and closing time.
- Good sealing, low friction between sealing surfaces, long life.
