Since the valves are provided with diaphragm there is no stuffing box. Absence of the stuffing box with the provision of leak tight bonnet diaphragm assembly eliminates leakage of fluids and gases. Thus it prevents corrosion (ultimately destruction) of other metal parts of the valve body.

* Reliable & Desired Closure : By provision of resilient Diaphragm, which is under the support and the pressure of compressor plate, seats against the weir, ensures leak proof closure even under the line pressure. It also facilitates desired throttling and smooth opening by handwheel operation.

* Low Pressure Losses : The design of the Valve Body is so streamlined that it permits optimum flow and hence ensures minimum pressure losses.

* Quick Maintenance : Due to versatile design the replacement of a Diaphragm is possible without disturbing pipe line, which saves valuable time.

* Easy Operation : The design of operational parts permits lubrication without opening the valve body. The Bi-metal use in operational parts and provision of thrust bearing in sizes above 50mm facilitates closure and opening very smoothly.
