BVS2 (Integrated SAE Flanged Port - Flange Head 61/62)
Holmbury’s BVS2 Series two-way 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.
Features
• Floating ball design maximises sealing • Full bore valves provide unrestricted flow path for negligible pressure drop • Open to close in 1/4 turn • Offset handle allows clearance for easy operation • Rotating flange
Accessories
• Valve locking kits and valve handles are available for the BVS2 Series
Construction
• AISI 316 stainless steel body (Some internal components carbon steel) • Zinc alloy handle • Forged steel option available • Fitted with FKM and POM seals as standard • Also available in carbon steel (See BVC2 Series)
Applications
• Marine • Offshore • Pharmaceutical • Power Generation
AVAILABLE SEALS AND TEMPERATURE RANGE
All carbon steel products have Nitrile Butadiene Rubber seals fitted as standard. All stainless steel products have Fluoro-elastomer Rubber (Viton®) seals fitted as standard. Special seal materials available on request.
