Wafer-Type Butterfly Valve with Signal Device

Description

Product Overview

The Wafer-Type Butterfly Valve with Signal Device is a key valve used in fire protection systems, industrial fluid pipelines, and automated control networks. Equipped with an electrical signal feedback device, it provides real-time status monitoring (open/close) to the control panel, ensuring operational safety and reliable system management.
Its wafer-type design allows easy installation between standard flanges, offering fast operation, low flow resistance, and stable sealing performance, making it a preferred control valve in modern fire protection systems.

Key Features

1. Valve Position Signal Feedback

Built-in micro switch device outputs open/close status signals for fire control panels or automation systems.

2. Wafer-Type Structure for Easy Installation

Compatible with various standard flanges and requires minimal bolts, reducing installation time and space.

3. Superior Sealing Performance

Uses high-quality rubber seals and corrosion-resistant disc materials for reliable sealing under high pressure and flow.

4. Clear Manual Wheel Indicator

Equipped with a manual wheel and clear position indication to assist visual inspection and maintenance.

5. Corrosion-Resistant Coating

Coated with corrosion-resistant epoxy for long-term durability, especially suited for wet fire system environments.
