BUTTERFLY VALVE

Special Purpose Rubber Lined

Butterfly Valve

Key Features

Full PN 10 pressure rating for the entire range of DN 50 to DN 350.

Bi-directional valve with sealing capability to hold rated shut-off

pressure in either direction.

A unique triple sealing system for shaft sealing eliminates any

fugitive emission or secondary leakage.

Self-lubricating shaft bearings (PTFE coated stainless steel) for
both drive end and non-drive end shaft ensures minimum

bearing friction torque.

The square coupling disc drive arrangement eliminates the need
for taper pins and exposure of metal parts to media.

Spherically profiled seat and disc shoulder contact area ensure
perfect sealing around the shaft bore and zero leakage.

External locking arrangement for the top shaft to make it

blow-out proof.

Excellent adaptability for actuated operation through standardized
top flange dimensions for actuator mounting.

Seat liner extending onto the flange contact faces of the body

eliminates the need for separate flange gaskets.

Controlled compression of the gasket sealing face to offer
optimum sealing and prevent gasket face crushing due to

over-tightening.
