Solenoid

A solenoid is an essential electrical control device that responds to an electrical signal (typically a 4- to 20-mA signal) by directing air supply to an actuator. There are two common types of solenoids: three-way and four-way, both widely used with actuators and positioners.

Three-way solenoids are suitable for operating single-acting actuators, such as diaphragm actuators, as they direct air to one chamber of the actuator. In double-acting actuators, three-way solenoids can interrupt or override an instrument signal to a pneumatic positioner. … actuators, three-way solenoids are used to interrupt or override an instrument signal to a pneumatic positioner.

Four-way solenoids are used in lieu of positioners to provide on-off operation of double-acting actuators, providing a positive two-direction action. Upon deenergization the four-way solenoids send full air supply to one side of the actuator, while exhausting the other side to atmosphere.

Actuators equipped with solenoids offer rapid response times, reliability, and cost-effectiveness for flow control solutions. Valveindo offers a comprehensive range of high-quality solenoid valves designed for reliability, efficiency, and seamless integration into various industrial processes.
