Electric Single-Seat Control Valve

The electric single-seat control valve consists of two components: the DKZ series linear-travel electric actuator and a straight-through single-seat valve. Powered by single-phase 220V AC, it receives 0-10mA or 4-20mA DC signals to automatically control the valve opening, achieving continuous regulation of process parameters such as pressure, flow rate, and liquid level within pipelines. This product features responsive operation, convenient power sourcing, and rapid signal transmission. It is widely used in industrial automation control systems across power generation, metallurgy, chemical processing, light industry, textiles, and other sectors.
