Scope of application

H61Y welded power station check valve is suitable for petroleum, chemical, hydraulic, thermal power stations and other working conditions with a nominal pressure of PN20.0 ~ 32.0Mpa and an operating temperature ≤540 ℃ (among which P (57) 170V operating temperature is 570 ℃) In the pipeline, cut off or connect the medium. Applicable medium: water, oil, steam, etc.

Structural features

Designed and manufactured according to E101 and JB / T3595-93 standards, the structure is reasonable and the performance is excellent.
The middle cavity of the valve adopts a pressure self-tight seal structure. The higher the medium pressure, the better the sealing performance.
The two ends of the branch pipe are butt-welded to meet different requirements of the connection.
The sealing surfaces of the valve disc and the valve seat are made of stellite cobalt-based hard alloy, which is hard-wearing, high-temperature resistant, good abrasion resistance and long service life.
The high-temperature and pressure-resistant parts are made of high-quality heat-resistant alloy steel, which is safe and reliable, stable in performance and long in service life.
