The electrical control box is composed of electrical converter, flow amplifier, main line pressure regulating valve, precision pressure regulating valve, filter and so on. Due to the use of a bifurcated circuit, 40 adjustable pneumatic actuators can be controlled at the same time, which saves a lot of components and greatly reduces the cost.

Integrated switch type pneumatic actuator

The pneumatic actuator is composed of a large-diameter stroke adjustable cylinder body, a mechanical position feedback, a special large-flow position-holding valve, a filter pressure-regulating valve, a solenoid valve, and a speed-regulating valve. The stroke can be adjusted according to the needs of the site, and the position can be automatically maintained in case of failure.

The pneumatic actuator is composed of a cylinder body, an intelligent positioner, a position feedback device, a position retaining valve, and a filter pressure regulating valve. It has the function of three-break protection (automatic position retention function when power off, signal off, and gas cut off), automatic adjustment of the position of the damper (electrical signal control: 4-20mA with 4-20mA feedback)

The pneumatic actuator is composed of an angular stroke cylinder body, an intelligent positioner, a position feedback device, a position retaining valve, a filter pressure regulating valve, and a balance valve. It has the function of three-break protection (automatic position retention or designated position when power is cut off, signal cut off, and gas cut off), and it can also be equipped with manual operation system. mechanism.
