Weir Orifice Diaphragm Valves

The simple functional construction of our Diaphragm Valve makes maintenance and pipeline inspection easy. A long useful life is assured by careful design and use of quality materials. There are two body alternatives available:

  • Straight screwed bodies from 15 mm (1/2") to 80 mm (3")
  • Straight flanged bodies from 15 mm (1/2") to 350 mm (14"), flanges are drilled to customers requirements.

A choice of hand-wheel or chain-wheel operated valves (with or without guides) are available. The diaphragm, which is made from raw materials to suit the fluids handled, isolates the moving mechanism from the fluids, thus ensuring protection of the compressor and spindle from being damaged by abrasive and corrosive fluids.

Valve Performance and applications:

Our Diaphragm Valve has an application in almost every industry. This proven system of controlling fluids together with high performance and trouble-free use in continuous application ensures minimum maintenance downtime. Designed for easy maintenance, the entire bonnet/diaphragm assembly can be withdrawn by simply loosening the bonnet nuts, thus leaving the valve body and pipe work in place. All Diaphragm Valve parts are independently manufactured and are interchangeable with other types of diaphragm valves.
