Overview

The commonly used structural forms of steam automation control valves include straight through single seat valves, straight through double seat valves, sleeve valves, eccentric rotary valves, butterfly valves, fully functional ultra light control valves, and ball valves. Based on different usage situations and the characteristics of different structural forms of valves, the structural form of the control valve should be evaluated from the aspects of control performance, applicable temperature, applicable diameter, pressure resistance, applicable medium conditions, cut-off differential pressure, discharge rate, pressure loss, weight, appearance, cost, etc.

Product Details

Steam automatic control valveIt uses compressed air as the power source, cylinders as actuators, and accessories such as electrical valve positioners, converters, solenoid valves, and security valves to drive valves, achieving on/off or proportional regulation. It receives control signals from industrial automation control systems to adjust various process parameters such as flow rate, pressure, and temperature of pipeline media. The characteristics of pneumatic control valves are simple control, fast response, and inherent safety, without the need for additional explosion-proof measures. Regulating valves have the characteristics of simple structure and reliable operation, but due to their direct contact with process media, their performance directly affects system quality and environmental pollution. Therefore, pneumatic regulating valves must be regularly maintained and inspected, especially in harsh and important environments where maintenance work should be emphasized.
