Stainless steel two way high pressure ball valves
Holmbury’s BVS 2 Series two way stainless steel, high pressure ball valves are designed to suit a wide range of applications. These valves should not be used as flow control valves and should therefore always be fully open or closed.
- Floating ball design maximises sealing
- Full bore valves provide unrestricted flow path for negligible pressure drop
- Open to close in 1/4 turn
- Cranked handle allows clearance for easy operation. Handles can be replaced.
- Valve Locking Kits (carbon steel) and Valve Handles are available for the BVS 2 Series
- AISI 316 stainless steel
- Fitted with Viton seals
- Also available in carbon steel (See BVC 2 Series)
- Metric and flanged available on request
- Handle zinc alloy (stainless steel available on request)
- Designed for usage in marine, offshore/onshore, pharmaceutical, power generation and offshore industries
