Weir Type Diaphragm Valve

Rubber Lined Diaphragm Valve – Weir ‘A’ Type

MVS Weir Type Rubber Lined Diaphragm Valve are manufactured in accordance with international standards. Available with a wide range of construction materials and lining options, the quality of MVS Rubber Lined Diaphragm Valve helps to deliver the full potential of a simple yet versatile and effective flow control design concept.

Valve bodies, linings and diaphragms in hundreds of different combinations offer tailored solutions to suit almost any corrosive or abrasive fluid. As the flowing media does not come into contact with the working components of the weir diaphragm valve, so total service life is dramatically increased.
