BUTTERFLY VALVE

BUTTERFLY VALVE (with tamper supervisory switch)

MODEL: SDBV-W, SDBV-W300 & SDBV-WTEC-175/200/250/300

Description:
Butterfly valves are rotary quarter-turn valves that use a circular disc as the closing element to regulate or isolate flow. Depending on design requirements, they can be concentric (symmetric) or eccentric (double or triple offset), offering reliable performance in various flow control applications.

Features:

• Versatile Design: Available in wafer, lugged, and double-flanged body types for easy installation and compatibility with different piping systems.
• Compact & Cost-Effective: Short face-to-face dimensions ensure space-saving installation and reduced material costs.
• High Performance: Offers excellent tight shut-off and smooth operation for both on/off and throttling control applications.
• Durable Construction: Designed for long service life under demanding industrial and fire protection conditions.
• Flow Control Efficiency: The modified equal-percentage flow characteristic makes them suitable for precise control.

Supervisory Switch Butterfly Valves:
These valves are equipped with a gear-operated hand wheel and supervisory switch for zone separation and monitoring in fire protection systems. They provide real-time position feedback for automation and safety systems and are suitable for both indoor and outdoor installations.

Advantages:

• Compact design requiring minimal installation space
• Easy operation and low maintenance
• Reliable tight sealing and corrosion resistance

Compliance:
In accordance with NFPA standards, indicating butterfly valves are used on the fire protection system side of the pump discharge check valve. Placement and installation requirements follow NFPA Clause 4.14.5.2, ensuring optimal safety and performance.

Applications:
Ideal for fire protection systems, HVAC, water distribution, industrial processes, and other fluid control applications.
