Diaphragm Valves are designed and manufactured
according to BS 5156. They are extensively
used in water treatment plants, fertilizer &
petrochemical industries, chemical process units,
refineries and power plants. They are suitable
for positive pressure and high vacuum applications.
Due to wide range of material options it is
suitable to handle almost all applications within
its pressure-temperature limitations.
wet area and working parts are isolated from
the working media by suitable lining with various
qualities of Rubber, PTFE/PFE etc. ensures handling
of highly corrosive fluids in efficient and
of these Valves are made very simple. By dismantling
the Bonnet from the Body, the entire Trim Assembly
can be taken out for maintenance and the Body
remains in the Pipeline. Thus the design permits
online maintenance and saves time and energy.
It has linear flow characteristics, which makes
it well suited to throttling or modulating duties.
On/off and control automation is provided with
Pneumatic Actuators or Cylinders.
Diaphragm Valves are available in varied
material like Cast Iron, S.G. Iron, Cast Carbon
Steel, Stainless Steel of all grades, High Alloy
Steels like Ally-20, CD4MCu., Hastelloy etc.
Manufacturing range starts from 15NB through
200NB and pressure rating in ANSI 125/150#.
