Casting Swing Check Valve

Casting Swing Check Valve

MAIN FEATURES:

The valve is opened or closed by the valve disc to rotate around the spindle outside the valve seat; and it is an automatic valve when it is automatically opened or closed by the force generated by the medium flowing within the pipeline. Its major function is to prevent the backflow of the medium in the pipeline, reverse rotation of the pump and its driving motor, and discharge of the medium in the container. 

 

Design Features

Design standard as per: BS1868,ASME B16.34, GB/T 12236.

Compact and reasonable product structure, reliable tightness and good performance;

Smooth fluid passageway and small fluid resistance;

Swing type disc.

Can be designed with a Damping Cylinder.

Rapid closing and flexible actions of the valve disc .

Small closing impact, water hammer is not liable to be generated.

Smooth fluid passageway and small fluid resistance.

Pressure Seal Check Valve

MAIN FEATURES:

The pressure seal valves are designed in accordance with BS1868 and ASME B16.34 for service of high temperature and high pressure and are widely used in fossil fuel power plant. Compared with bolted bonnet joint valves, it provides absolute reliable sealing of the bonnet joint, so that the pressure seal valves are more compact and rigid as well as maintenance cost-effective at high temperature and high pressure service.

 

It is an automatic valve when it is automatically opened or closed by the force generated by the medium flowing within the pipeline. Its major function is to prevent the backflow of the medium in the pipeline, reverse rotation of the pump and its driving motor, and discharge of the medium in the container.  

 

Design Features

Design standard as per: BS1868,ASME B16.34, GB/T 12235, JB/T3595.

Only one sealing face is designed on the valve body and valve disc,

Full stellite overlay seat sealing surface

Good for manufacturing process and easy to maintain.

Use flexible and woven graphite collaboration type packing.

Absolute bonnet joint leak proof.

Optional by-pass design.

Optional designed with a Damping Cylinder.

Wafer Type Dual Disc Check Valve

MAIN FEATURES:

Two arch disc are fixed onto the valve body with a spindle on which two torsional springs are equipped for installing the butterfly plate onto the valve body sealing face. The butterfly plate pressed by the springs is opened by relying on the medium pressure, and the valve is closed by the spring force and the medium pressure under backflow. It can be installed on horizontal and vertical pipelines.

 

Design Features

Design standard as per: API 594, API 6D,ASME B16.34, GB/T 12236.

Compact and reasonable product structure, reliable tightness and good performance; 
Small volume and light weight; 
Applied widely; 
Rapid closing and flexible actions of the valve clack 
Small closing impact, water hammer is not liable to be generated; 
Smooth fluid passageway and small fluid resistance;
