Salient Features

• Meet design specification as per BS 5156 / B 16.34 / Flange dimensions as per B 16.5

• Testing Standard as per BS - EN 12266 - 1 / DIN – EN - 588 – 1

• Lining Standard as per ASTM F 1545

• The Weir type top entry Diaphragm valves provide tight shut-off with comparatively low operating force.

• A simple and reliable weir design valve is better throttling flow or block flow at valve fully open it offers a self cleaning design. It is the best choice for dirty, contaminated and powder media. Specifically suited to handle erosive and abrasive application

• When require to the replacement of the Diaphragm, the bolted bonnet design permits the dismantling of the valve without removing the valve body from the pipe joint.

• Convection Isolating valve would require expensive exotic materials to resist the effects of sever corrosion.

• High permeation resistance lining.

• Soft – sealing, gas tight shut – off.

• Vacuum proof anchored.

• Hermetic – Gland less sealing against the valve bonnet.

• The quality and functionally of the diaphragm are crucial for greater Fatigue strength under reversed bending stresses and dimensional stability even after many switching cycles and at fluctuating temperatures.

• Higher density and lower permeability.

• Travel position indicator gives clear and positive from any angle.

• PTFE Bearing: Minimizes friction between stem and compressor.

• Exclusive sealing bead design prevents best seal and reducing thermal stresses on the sealing surface.

• cavity free, poke less design ensures unrestricted flow and low pressure drop.

• Floating tube diaphragm Nut design ensures uniform distribution of the stem closing force and the PTFE Diaphragm reducing cold flow.
