BVS2 Series (Limit Switch)

BVS2 (Limit Switch)

Holmburys’s BVS2 Series two-way high-pressure ball valve
with an integrated positional detection device. When closed,
a limit switch will send an electrical signal to a remote display
to monitor the “open” or “closed” state.

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
• Positional Switch: AC 380V DC 220V 5A

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
