Wafer Check Valves

Lixin — Sat, 10 May 2025 03:38:54 +0000

Lixin Wafer Check Valve its due to the better flow performances, smaller installation space, lower weight and easier installation, dual plate check valves are widely used in the flow control industry . Relying on the spring force and the medium pressure under backflow the valve will be closed .

Main Features :

Lixin Wafer Check Valve design is generally stronger, lighter, smaller, more efficient and provides lower installation cost. Suitable for horizontal or vertical positions. In horizontal position flow allows plates to function free and under lower flow conditions as compared to swing check – Reduces pressure loss, improves dynamicthse and eliminates valve chatter.

Design Features :

Compact and Simple Structure with good tightness;

Applied widely;

The valve disc closing rapid and actions flexible ;
Fluid Passageway Smoothly and small fluid resistance;

Forged Check Valves

Lixin — Sat, 10 May 2025 03:31:02 +0000

Forged Check Valve is the disc by its own weight and the medium pressure action to block the reverse flow of the medium .It may also be used in pipelines to supply auxiliary systems in the pressure may rise above the system pressure.

Main Features :

Lixin Forged Check Valve are commonly used as bottom valves in pumping units to prevent backflow of water .Disc movement is divided into lifting type and swing type .Lift-type check valves are similar to globe valves except for the absence of a stem to drive the disc. The medium flows in from the inlet end (lower side) and out from the outlet end (upper side). The valve is opened when the inlet pressure is greater than the combined weight of the disc and its flow resistance.Conversely, the media flow back when the valve is closed.Swing check valves have a tilted disc that rotates about the shaft and work in a similar manner to lift check valves.

Design Features :

Bolted Bonnet and Pressure Seal are optional ;

Applied widely;

The valve disc closing rapid and actions flexible.

Small closing impact, water hammer is hardly to generated;

Cast Check Valves

Lixin — Sat, 10 May 2025 03:30:40 +0000

Cast Check Valve is known as one-way valve or non-return valve. The valve closes automatically driven by flow and force of medium to prevent backflow of medium. They are mainly applied on pipeline with medium flows in one direction.

Main Features :
Lixin Cast Check Valve is used to prevent back flow in the line. Flow is in a straight line through the valve resulting in minimal pressure drop. The disc swings into the open position as the media flows through the line. Back pressure in the line holds the disc in the closed position.

Design Features :

No manual intervention is involved in the whole process.

Swing Type or Lift (Piston) Type;

Bolted Bonnet and Pressure Seal;

Applied widely;

Rapid closing and flexible actions of the valve disc;

Small fluid resistance and large valve flow coefficient

Operation

Application

A lift check valve is used to prevent the backflow of any stream, whether it is liquid, gas, vapor, or any solidified stream. There is a certain pressure required to open the check valve. If the pressure becomes less, the valve will automatically close, or additionally, it prevents the stream from flowing in the opposite direction.

Other

The carefully selected materials and contemporary design make our check valve highly recognized.

If our check valve cannot meet your choice, we can provide you with special made.

Chief Features

Controlled by a plug that lifts as the valve fills up with media, the Lift Check Valve (or Piston Check Valve) is ideal for gas, liquid, air, and vapor pipeline connections. Available in horizontal, vertical, and angular body patterns, our lift check valves keep released media from returning when the plug returns to its original place.

The valve can be opened and closed automatically by medium force

Ss+ graphite or metal seal is used between valve body and valve cover, and the sealing is reliable

The sealing surface of valve seat and disc is overlaid with cemented carbide to improve the scouring resistance and prolong the service life of the valve

Lift check valve disc can also be spherical at high pressure
