Batley Valve® BV 18000 PTFE Lined Batseal
The Batley Valve Batseal valve design incorporates PTFE to obtain maximum corrosion resistance for both shutoff and control of line fluids. This valve has bubble-tight shutoff up to 10 bar, depending upon operating temperature. Disk and spindle are normally manufactured as a one-piece unit. Lining-molded Teflon FEP or virgin PTFE liner protects the body from the line fluid. Resilient silicone rubber backup strips between body and lining ensure positive contact with disc at all times.

- Use of PTFE (FEP) for body lining and vane/spindle coating negates the need for costly corrosion-resistant alloys.
- Bubble-tight shutoff up to 10 bar, Viton seal is used to prevent ingress of dirt or corrosive gases from the atmosphere and acts as a secondary gland.
- Self-lubricated, PTFE-faced Glacier Du bearings combine low friction with high load bearing properties.
- Resilient silicone rubber backup strips between body and lining ensure positive contact with disc at all times.
- A stainless steel tapered plug backed up by a resilient silicone rubber ring ensures positive contact and sealing among lining, disc and spindle.
