Product Description

Product name: Forged steel Y-type check valve
[Product model: H65Y-800LB]
[Product introduction] :
H65Y forged steel Y-type check valve body, valve cover bearing parts are forged with integral mold, used in high temperature or high pressure working conditions, such as thermal power plants, nuclear power plants, petrochemical system of high temperature, high pressure pipe to prevent the flow of media in the pipeline.
[Working principle] :
H65Y forged steel Y-type check valve when the medium flows into the valve body as shown by the arrow of the valve body, the pressure of the medium acts on the valve disc to produce upward thrust, when the medium thrust is greater than the gravity of the valve disc, the valve opens. When the force of the medium pressure acting on the valve disc after the valve plus the gravity of the valve disc itself is greater than the force of the pressure acting on the valve disc before the valve, the valve is closed to prevent the backflow of the medium.
[Product features] :
1, the valve flap can be transformed into a spherical seal (spring with steel ball).
2, pressure seal design and graphite gasket ring to ensure high air tightness.
3, the guide bar on the surfacing welding carbide valve body cavity guide sleeve made of stainless steel material to ensure that the valve flap flexible action.
4. The sealing surface of valve disc and valve seat is made of cobalt-based cemented carbide plasma spray welding with high hardness, erosion resistance and durability.
