Batley Valve®
BV 34000 Vulcanised rubber lined
Vulcanised rubber lined butterfly valves developed to address a high quality, low cost valve, for use on corrosive line fluids such as seawater and brine.
The Batley Valve® BV 34000 vulcanised rubber lined butterfly valve incorporates a liner that is bonded to the valve body, allowing this to have higher closed differential pressures from full vacuum up to 20 bar g and the potential for higher fluid velocities up to 8 metres per second. The valve body incorporates a small raised spigot that prevents the body liner from being over compressed during installation.
KEY FEATURES/BENEFITS
- The valve is ideally suited to the dual role of process isolation and control and as such can be fitted with a wide range of manual and powered operators.
- The design is such that the body and shaft material is fully isolated from the line fluid and as such lower specification materials such as Cast Iron & Carbon Steel can be used in lieu of the more expensive AL Bronze and Stainless Steel.
