Electric wafer butterfly valve consists of a high-precision electric actuator and a wafer-type butterfly valve. The actuator features an integrated structure. The on-off type is powered by AC220V with passive contact signal output (or open/close indicator signal). The modulating type can be controlled by DC4-20mA or DC1-5V control signal plus single-phase power supply.

Electric wafer butterfly valves feature good functionality, compact size, lightweight, cost-effective, reliable performance, simple configuration and large flow capacity. They are suitable for viscous, particulate and fibrous media. They are widely used in automatic control systems for food, light industry, petroleum, chemical, educational equipment, paper making, power and other industries.

Features

• Remote control is available. The butterfly valve can be controlled by electrical signals via the electric actuator.

• Available in on-off type and modulating type, supporting both open/close control and flow regulation.

• Among all valves, wafer butterfly valves have the shortest face-to-face dimension, smallest space occupation and low cost.

• Soft seat is usually made of elastic material, embedded in the groove of the valve body to ensure bubble-tight sealing, ideal for zero-leakage applications.

• The soft seat features high elasticity and strong sealing performance, and is replaceable to reduce cost.

• CF8 (304 stainless steel) disc provides oxidation resistance, corrosion resistance and good performance in most mildly corrosive media.
