The WM Diaphragm Valve is an outstanding product that has proven its self in the South African Mining industry for the past three decades. We now proudly boast the worlds first 25 bar rated range of Diaphragm Valves for slurry. This outstanding Range of valves is our company’s flagship product. We are the sole Producer of the WM Diaphragm valve and the only licensed repairer of this outstanding range of slurry valves. WM Diaphragm Slurry Valves are of an advanced design (patented) which provides straight-through flow whilst restricting to a minimum the flexing stress imposed on the diaphragm. The internal contours of the body ensure smooth flow and are suitable for all types of protective lining. The greatest advantage of diaphragm valves is their extreme versatility and this is well developed in the WM S type. A wide selection of body materials coupled with a variety of highly developed rubbers and synthetics for the diaphragm enable the valve to handle the widest possible range of duties. The diaphragm is moulded in the ‘open’ state and has therefore no tendency to stick ‘closed’, this increases the life span of the diaphragm as it is only in the working position once the valve is closed which studies show to be ± 20% of the time.

Advantages of a Diaphragm Valve

• A Diaphragm Valve is able to be repaired while online by simply replacing the bonnet assembly.
  This greatly reduces down time, which we all know costs more than any valve ever could.
• Spares are easy to replace which allows for the Bonnet assembly to be repaired on site.
• Valve stock is kept to a minimum as spares are kept instead of complete valves.
• Valve costs are radically reduced due to the above-mentioned advantages.
