Plastic Valve Diaphragm Valve

A diaphragm valve consists of a valve shell and a corresponding diaphragm valve core. Its working mechanism is based on the movement of the diaphragm. There is a sealing seat in the middle of the valve shell. The diaphragm moves up and down through the operation of the handwheel to open or close the flow channel.

The internal structure of the valve body is relatively simple. The inner surface of the valve body is usually lined with materials such as glass, enamel, synthetic resin, or rubber. The diaphragm is typically lined with rubber and synthetic resin. These valves are suitable for corrosive fluids due to their smooth flow characteristics and are often used in applications involving slurries.

Leverage Relief Valve - A weight is placed on one end of the lever, and the valve core is loaded at the other end.

Spring Balance Valve - The lever is loaded to balance the load of the valve core.

Others - To prevent explosions caused by pressure rises and to ensure the necessary airtightness during operation, a thin metal sheet explosion-proof membrane type safety device can be used in such cases.

The relief valve for steam and gas has a slightly different operating mechanism from that of the safety valve used for liquids. There are many regulations regarding relief valves, so when making a selection, the most important thing is to ensure compliance with the relevant rules.

Steam Trap - Automatically removes condensate from steam pipes. Types include disc, ball float, double vertical, and bucket types.

Other Special Valves - These include shells lined with rubber or synthetic resin, throttle valves with closed flow paths, and vacuum valves for vacuum systems.
