FAPL-310N butterfly valve position feedback head solenoid valve 4V310-08B

Butterfly valve position feedback head solenoid valve, the solenoid valve can meet the two assembly requirements of plate connection type and pipe connection type, and has the functions of two-position five-way and two-position three-way. It can directly control single-acting and double-acting pneumatic actuators, and is equipped with a safe and reliable manual device on the pilot. It is a truly universal solenoid valve. Due to its unique air path structure, all breathing holes on the solenoid valve body are connected to the exhaust holes. There are no breathing holes on the surface of the valve body that are connected to the atmosphere. This can effectively prevent external liquid dust and impurities from entering the valve body. It is especially suitable for outdoor use. Or used in working environments with serious dust pollution. Air source working pressure. Explosion-proof junction box valve position switch valve replyer
Three-position control module, three-position control is widely used in the valve position control of three-way ball valves or plug valves. Most of the current solutions use three-position pneumatic actuators plus three solenoid valves to implement decentralized control, but the cost is high and installation is difficult and on-site adjustments are troublesome. A series of three-position valve controllers are installed on two-position pneumatic actuators, which can be adjusted The controllable and stopable zero position, neutral position and off position provide a three-position control solution easily and have the function of delaying and resisting water hammer. Features Accurate positioning error + degree, accepts low-frequency pulse signals, zero-to-full-scale middle position, can feedback accurate signals of three positions, simple and convenient installation, can be directly installed on ordinary two-position cylinders, meeting the requirements of three-position control, and can Set the delay, clockwise and counterclockwise are optional.
