Weir valve incorportates a rubber seal clamped to the vane edge
to ensure 360 degrees seal contact in the closed position.
The Steadseal Butterfly Valve incorporates a
rubber seal clamped to the vane edge and is designed to ensure a
uniform 360° seal contact in the closed position. The double
eccentric action moves the vane into and out of the bodyseat with
the minimum of wear and seating torque. This valve is particularly
suitable where both tight shut-off and control is required.
Light Duty series “LD” valves for very low
pressure applications (5psi shut-off), and double flanged valves
are available.
Features / Benefits
- Double eccentric action moves the vane into and out of the seat
with minimum wear and seating torque, giving longer seat life and
reduced overall valve torque.
- Valve Body in either Ductile Iron or Carbon Steel is protected
with a number of different linings to suit each
application.
- Sealing Ring is easily replaceable.
