Regus Regus imported pneumatic diaphragm valve
Pneumatic diaphragm valves are a special form of shut-off valve that appeared in the 1920s. Its opening and closing member is a diaphragm made of soft material, which separates the valve body cavity from the bonnet inner cavity and the driving component, so it is called a pneumatic diaphragm valve. The most prominent feature of the pneumatic diaphragm valve is that the diaphragm separates the lower valve body cavity from the inner cavity of the upper bonnet, so that the valve stem, valve disc and other parts located above the diaphragm are not corroded by the medium, eliminating the packing sealing structure and not generating The medium is leaking.

Regus Regus imported pneumatic diaphragm valve definition:
Structural characteristics and working principle of normally closed pneumatic diaphragm valve
1. The biggest difference between the diaphragm valve and other valves is that it adopts the structure without the stuffing box; the rubber diaphragm can make the corrosive medium in the flow channel completely separated from all the driving parts, thus eliminating the "running, running, Drips, leaks, etc.
2. Since the flow path of the diaphragm valve is smooth and the flow resistance is small, a large flow rate can be obtained.
3. The surface of the valve body cavity of the plastic diaphragm valve depends on the various rubbers selected for the hall. Therefore, it has superior corrosion resistance.
4. Because the seal is a flexible rubber diaphragm. Therefore, it also has better sealing and minimum closing force.
5. The valve consists of valve body, valve cover, valve disc, valve stem, diaphragm and other drive parts.
6. The opening and closing of the valve is achieved by rotating the hand wheel. The diaphragm valve is marked with a display color at the upper end of the valve cover to indicate the opening or closing position of the valve to indicate the opening and closing stroke of the valve. When the handwheel is placed clockwise, the handwheel moves down, and the valve flap drives the diaphragm down to cut off the passage; otherwise, the valve opens and the color is revealed.
