Wafer check valve (DH77X)


The valve is composed of valve body, valve disc, valve stem and spring and other parts, using the clamp connection. Due to the short closing stroke of the disc and spring loading, water hammer can be significantly reduced. Mainly suitable for urban, industrial and high-rise building water supply, drainage pipe network and other non-corrosive media on the pipeline, to prevent the medium reverse flow of one-way opening and closing.

German standard swing check valve (H44X/T)


The valve is suitable for nominal pressure PN1.6-4.0MPa, working temperature -10 ℃ ~ 350 ℃ of petroleum, chemical, pharmaceutical, fertilizer, power industry and other working conditions of the one-way opening and closing pipeline cut off or connected to the pipeline medium.

Discover how check valves enhance efficiency and safety in various industrial applications.

Introduction of check valve


Check valve, also known as one-way valve or check valve, its role is to prevent the backflow of media in the pipeline. Includes swing check valve and lift check valve. Swing check valves have a hinged mechanism and a door-like disc that rests freely on the inclined seat surface.

Special valve selection matters needing attention


Most of the fluid media used in the process industry involve oil and gas streams of different corrosive grades. These flow conditions, including medium flow, are considered to be either clean, dirty, or worn (mud conditions), and the difference lies mainly in the number and type of solid suspended particles that cause valve blockage or corrosion damage.

Valve logo and model, entry must see!


Beginners of the valve always mistake the faucet for the valve. In fact, not also, the faucet belongs to the bathroom series in the strict sense. Valve is divided into gate valve, globe valve, butterfly valve, high pressure valve, low pressure valve, fluorine valve, safety valve, pressure relief valve, anti-corrosion valve, filter, check valve, pressure reducing valve, over-flow valve, ceramic valve, medium pressure valve, high temperature valve, low temperature valve and so on.
