Product Overview:

LXHQ check valve is a kind of automatic opening and closing valve, which uses the flow pressure of the medium itself to push the valve disc to open, and automatically closes when the reverse flow occurs. It is used to prevent the reverse flow of the medium and protect the safe operation of the pump, compressor and equipment. The valve has the characteristics of simple structure, sensitive response, stable work and the like, and is widely applied to fluid pipeline systems of industries such as water supply and drainage, petrochemical industry, electric power, metallurgy, pharmacy, food and the like.

Product features:

One-way flow control of medium to prevent backflow and water hammer

No external drive, automatic opening and closing, reliable operation

Sensitive opening and closing, suitable for low pressure or gravity system

Various structures (lifting type, swing type, butterfly type, ball type) can meet different installation positions

Good sealing performance, suitable for liquid, gas, steam and other media

Clear installation direction, easy maintenance and long service life

Can be installed horizontally or vertically (some structural constraints)

Multiple connection modes to adapt to different pipeline standards
