Single-seated Control Valve
The single-seated control valves have a top guiding structure. The valve body flow path is in the S type which provides a lower pressure loss, larger flow capacity, wider control range, higher control accuracy and offers a better performance in resistance to vibration.
The single-seated control valves have a top guiding structure. The valve body flow path is in the S type which provides a lower pressure loss, larger flow capacity, wider control range, higher control accuracy and offers a better performance in resistance to vibration. Valves are usually equipped with a pneumatic diaphragm actuator with a compact whole structure, high anti-pressure ability and can be applied to control different pressure and temperature fluid.
