Our PN40 stainless steel double flap check valve features a simple, reliable and compact design that allows the fluid (liquid or gas) to flow through it in only one direction, allowing flow in that direction and automatically preventing backflow. (reverse flow) when the fluid in the line changes direction. Made of steel with high corrosion resistance, ideal for places where the properties of steel and its resistance to corrosion are needed.<\/p>\n
The two discs are opened by the pressure of the circulating fluid, allowing the fluid to pass in the desired direction. When the flow stops, the valve closes quickly with the help of the closing spring, thus preventing reverse flow. The grooved vulcanized nitrile sealing gasket ensures perfect sealing and makes it suitable for a wide variety of working fluids.<\/p>\n

It has an O-ring on each face that allows direct installation to flanges without the need for gaskets.<\/p>\n
This type of valve is designed to operate efficiently in horizontal pipes or vertical (with ascending or descending fluid direction), has a useful life long and operate easily, even under low pressure conditions.<\/p>\n","protected":false},"excerpt":{"rendered":"
