Diaphragm Valves

Our diaphragm valves are specified in a wide range of applications; from abrasive slurries to water treatment and general industrial applications. 

Straight Orifice Diaphragm Valves

Valve Design:

Careful design and the use of quality materials assure a long useful life of our Diaphragm Valve. The straight-through type passage of the Type "SO" valves ensures minimum restriction when the valve is open, thus giving maximum flow to even the densest fluids. There are two body alternatives available namely:

  • Straight screwed bodies from 25 mm (1") to 80 mm (3")
  • Straight flanged bodies from 25 mm (1") to 350 mm (14") (Flanges are drilled to your requirements)

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

Straight Through Diaphragm Valve

Valve Performance and Valve Application:

The excellent flow characteristics achieved with the “SO” Diaphragm Valve ensures trouble-free performance even when handling thicker fluids, such as sludge and slurries. This proven system of controlling fluids together with a robust and simple construction makes for 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 Designed for easy maintenance, the entire bonnet/diaphragm assembly can be withdrawn by simply loosening the bonnet nuts, thus leaving the valve body and pipe work in place. The “SO” Diaphragm Valve has a wide range of applications in industry some examples are:

  • Foodstuffs
  • antibiotics
  • effluents
  • commercial vacuum duties

All parts are independently manufactured and are interchangeable with other types of diaphragm valves.

Valve Features:

Straight-through passage.
Robust construction.
Minimal resistance to flow.
Positive isolation of valve mechanism.

Glandless construction.


Weir Orifice Diaphragm Valves

Valve Design:

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.

Straight Orifice Diaphragm Valve

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.

Valve Features:

Flexible, reinforced diaphragm.
Operating mechanism protected from corrosion.
Compressor ensures tight closure.
Robust construction.
Positive isolation of valve mechanism.
Streamlined fluid flow.
Parts are interchangeable.

Valve Advantages:

100% SA. Manufacture.
Leak-proof.
Low flow resistance.
Long life.
Easy maintenance.
Sure closure.
