Description

Product Overview

The Lockable Butterfly Valve is a key control valve used in fire protection pipelines, industrial water supply systems, and various pressurized networks. It features an integrated locking mechanism that allows the valve to be secured in either the open or closed position, preventing accidental or unauthorized operation. Built with high-strength cast construction, it is ideal for long-term use in high-pressure and high-flow environments, commonly functioning as a main control valve in fire protection systems.

Key Features

1. Secure Locking Mechanism

Allows the use of padlocks to secure the valve position, preventing accidental or unauthorized operation—ideal for fire protection systems requiring strict operational control.

2. High-Strength Valve Body

Manufactured with pressure-resistant cast materials, offering excellent mechanical strength and impact resistance for demanding and long-term applications.

3. Fast Operation with Low Flow Resistance

The rotating disc design enables fast and light operation while maintaining low fluid resistance.

4. Corrosion-Resistant Coating

Coated with corrosion-resistant epoxy or fire-protection red coating, making it suitable for humid environments and outdoor applications.

5. Compatible with Alarm Valve Assemblies

Frequently used as a primary control valve in wet alarm valve assemblies and general fire pipelines.
