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. 
Stainless Steel Materials

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
