Diaphragm valves are bi-directional, on-off throttle valves. They are used to control fluid flow by regulating the area with which media can enter and exit the valve, effectively changing its speed and velocity. They are so-called “diaphragm” valves because a thin, flexible membrane is used to control the opening and closing of the valve.


Butterfly valves are easy and fast to open. A 90° rotation of the handle provides a complete closure or opening of the valve. Large Butterfly valves are usually equipped with a so-called gearbox, where the handwheel by gears is connected to the stem. This simplifies the operation of the valve, but at the expense of speed.


Diaphragms are sealing agents, used as moveable membranes to prevent two or more components from leakage and friction. The flexible nature of this seal allows pressure effects to cross the barrier but not the material being contained.


Catering to the ever growing and changing demands of our customers, we are engrossed in providing Teflon Coated Rubber Diaphragm.

Rotary Air Valve

The prime function of a rotary airlock (rotary valves) is to regulate the flow from one chamber to another while maintaining a good airlock condition. ... Airlocks are also important in the pneumatic conveying industry, where product is regulated into a pressure or vacuum conveying line while minimising air leakage.
