The valves are essential part of any chemical process plant, pharmaceuticals and allied industries in a wide range of application from relatively simple on/off function to control, pressure relief and filtering.

The valve bodies are of borosilicate glass and PTFE bellows. The PTFE bellows is flanged at one to seal between the valve body and bonnet part, as a result operation of the valve can be checked visually. In practically every case glass is combined with PTFE, which ensures that the valves have maximum resistance to corrosion. All the valves in the range are suitable to use under full vacuum.
