02250049-634 Sullair Genuine Original BLOWDOWN VALVE

Overview

Sullair’s automatic basic components used to control fluids belong to actuators, not limited to hydraulics and pneumatics. Used in industrial control systems to adjust the direction, flow, speed, and other parameters of the medium. The INLET/BLOWDOWN VALVE can cooperate with different circuits to achieve the desired control, and the accuracy and flexibility of the control can be guaranteed.

There are many types of Sullair INLET/BLOWDOWN VALVE. Different solenoid valves play a role in different positions of the control system. Commonly used are check valves, safety valves, directional control valves, speed control valves, etc.

Sullair IR air compressor solenoid valve selection basis: according to the pipeline parameters to select the solenoid valve: diameter specification (namely DN), interface mode.

1) Determine the diameter (DN) size according to the pipe inner diameter size or flow requirements on site;
2) Interface mode, generally >DN50 should choose flange interface, ≤DN50 can be freely selected according to user needs.

When the coil is energized or de-energized, the operation of the magnetic core will cause the fluid to pass through the valve body or be cut off to achieve the purpose of changing the direction of the fluid. The electromagnetic components of the Sullair solenoid valve are composed of a fixed iron core, moving iron core, coil, and other parts; the valve body part is composed of the spool valve core, spool valve sleeve, spring base, and so on. The solenoid coil is directly installed on the valve body, and the valve body is enclosed in a sealed tube, forming a simple and compact combination. The solenoid valves commonly used in our products include two-position three-way, two-position four-way, two-position five-way, etc.

Let’s talk about the meaning of the two positions: for the Sullair solenoid valve, it is charged and de-energized, and for the controlled valve, it is open and closed. In the oxygen generator instrument control system, the two-position three-way solenoid valve is mostly used. It can be used to connect or cut off the gas source in production, thereby switching the pneumatic control membrane head gas path. It is composed of a valve body, a valve cover, an electromagnetic component, a spring, and a sealing structure. The sealing block at the bottom of the moving iron core closes the air inlet of the valve body by the pressure of the spring. After energizing, the electromagnet attracts and the sealing block with a spring on the upper part of the moving iron core closes the exhaust port, and the airflow enters the membrane head from the intake port, which plays a control role. When the power is lost, the electromagnetic force disappears, the moving iron core leaves the fixed iron core under the action of the spring force, moves downwards, opens the exhaust port, blocks the air intake, the airflow of the membrane head is discharged through the exhaust port, and the diaphragm recovers Original location. In our oxygen production equipment, it is used in the emergency shut-off of the membrane regulating valve at the inlet of the turboexpander.
