Characteristics Of Electric Stop Valve

The fluid resistance is small, and its resistance coefficient is equal to that of a pipe section of the same length.

The Difference Between Bellows Stop Valve And Ordinary Stop Valve

Double sealing design (bellows + packing). If the bellows fails, the valve stem packing will also prevent leakage and comply with international sealing standards.

Check Valve Troubleshooting

The medium pressure before and after the check valve is in a state of close balance and "see-sawing" with each other.

Check Valve Selection Criteria

In order to prevent the backflow of the medium, check valves should be installed on equipment, devices and pipelines;

Check Valve Process Design

Quality control of the main body blank. All parts of this valve are forgings. During forging, they are strictly carried out in accordance with the forging process regulations and process cards.

Check Valve Installation Precautions

Do not let the check valve bear weight in the pipeline system. Large check valves should be supported independently so that they are not affected by the pressure generated by the pipeline system.

Check Valve Installation Method

The disc of the swing check valve is disc-shaped and rotates around the rotating axis of the valve seat channel.

Classification Of Check Valves

The opening and closing parts open or close on their own by the force of medium flow to prevent the medium from flowing back. The valve is called a check valve.

Check Valve Working Principle

Check valves may also be used on lines supplying auxiliary systems where the pressure may rise above the system pressure.

Introduction To Check Valve

Check valve refers to a valve whose opening and closing parts are circular discs and rely on their own weight and medium pressure to act to block the reverse flow of the medium.

Ball Valve Operation Precautions

It is necessary to confirm that the pressure in the upstream and downstream pipelines of the ball valve has been relieved before proceeding with the disassembly and disassembly operation.

Ball Valve Applicable Occasions

Since ball valves usually use rubber, nylon and PTFE as seat sealing ring materials, their service temperature is limited by the seat sealing ring material.
