Pneumatic Single Seat Regulating Valve

S J Pneumatic Control Valve series Pneumatic Single Seat Regulating main functions include regulating flow, controlling pressure and liquid level. The design of the pneumatic flow control valve plug allows equal amount of flow control required for the required Kv factor. This type of pneumatic manual control valveis recommended for systems with increased flow or pressure differential. Positioning can be controlled manually or using process parameters via positioning sensors.This SJ valve is a pneumatic control valve designed for accurate flow regulation in industrial piping systems. Combining a blue pneumatic actuator, positioner, pressure gauge, and robust valve body, it supports reliable pneumatic flow control and pneumatic manual control valve functions. It is suitable for process control, fluid regulation, and industrial automation applications.
