Description
The KLD200 motorized wafer butterfly valve (metal) is constructed with a die-cast aluminum body and a disc made of 304 or 316 stainless steel, providing reliable performance and good corrosion resistance. It features a fail-safe function and offers the option for normally open or normally closed operation, making it a robust alternative to solenoid valves. The valve is electrically driven and includes a manual override via a hex key for safe and convenient operation during power loss. With its compact design, it is ideal for integration into small equipment and supports remote control automation. The valve also boasts an IP67 protection rating, ensuring excellent waterproof and dustproof performance.

※2 It needs to add high-temperature bracket if medium temperature is over 100℃.
Notes: Type S adopts micro-motion feedback, which can maintain the signal status after power failure with a slight delay relative to the valve position action. If synchronous feedback signal with the valve position is required, the 200C-J relay feedback solution is recommended, and detailed technical parameters can be obtained by consulting our customer service.
