Batley Valve® BV 20000 Steadseal
This double-eccentric rubber seal butterfly valve is designed to ensure a uniform 360° seal contact in the closed position. The Batley Valve® Steadseal 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 body seat with the minimum wear and seating torque. This valve is particularly suitable where both tight shutoff and control are required. For on/off service, the valve can be operated manually or by an automatic actuator.

- 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. The valve is suitable for through-bolt mounting between flanges to BS4504, BS10, BS1560, ANSI or DIN. The vane’s streamlined design improves the flow line and reduces the head loss.
- PTFE-faced, self-lubricating Glacier DU bearings are normally fitted and adequately provide for the high-loading, low-friction requirements.
- Stainless steel seat is provided for general applications but for strictly non-corrosive services such as clean air; body bore is coated with an anti-corrosive surface treatment. The resilient seat has a high-quality nitrile rubber ring attached with the vane edge with a steel clamping ring.
- Alternative seals are Viton, Butyl, Neoprene and Ethylene Propylene.
