Description
Overview
The KNKE Electric Butterfly Valve is designed for both on-off and modulating control. The valve features an integrated structure that connects directly to a 220VAC power supply. When equipped with a control module, the valve can regulate based on 4-20mA or 1-5VDC input signals. With a compact design and reliable performance, the KNKE Electric Butterfly Valve is ideal for systems requiring precise control of temperature, pressure, flow, and level, particularly in industries such as food, environmental protection, chemical, and power.
Key Features
- Dual Eccentric Design: Ensures a tight shutoff with reliable sealing properties that improve over time.
- Long Service Life: Features durable sealing materials, including stainless steel and nitrile rubber for extended valve life.
- Flexible Sealing Options: Can be customized with soft seals for clean media or hard seals for high-temperature, high-pressure applications.
- Compact and Lightweight: Easy to install and maintain, saving space while offering large flow capacity.
- Bidirectional Sealing: Installation is not affected by the flow direction or position, providing flexibility in use.
- User-Friendly: Offers easy operation and low maintenance requirements.
