High pressure butt welding check valve Product Description:

H62Y high pressure butt welding check valve is widely used in the pressure of PN16-45Mpa, temperature -20- +450 ℃ water, oil, natural gas pipeline system and oil field system. The valve body, valve flap, spring and central axis.
 

High pressure butt welding check valve works:

When the medium flows into the valve body by the arrow of the body, the pressure of the medium acts on the valve flap to generate an upward thrust, and when the medium thrust is greater than the gravity of the valve flap, the valve is opened. When the valve medium pressure on the role of the valve with the force of the valve itself is greater than the pressure before the valve pressure on the role of the valve, the valve closed to prevent the media back.
 

High pressure butt welding check valve Features:

1, the structure of a very short length, small size, light weight, installation of the valve, handling, storage pipe layout has brought great convenience, and can save a lot of material, reduce costs.

2, the overall structure of the valve, simple and compact, small impact when the valve is closed, water hammer pressure is small, the valve life is long, high reliability.

3, can be horizontal or vertical installation, light weight, do not have to set the valve support.

4, smooth flow path, fluid resistance is small, the valve can be fully opened in a small pressure drop.

5, the valve disc and seat sealing surface made of cobalt-based carbide plasma spray welding, high hardness, erosion resistance, durability.
