Description

Pneumatic Solenoid Valve 070131 pilot Operated Solenoid Control Valve 24V Laminating Machine Two Position Three-way Vacuum

Working Principle:

The pilot – operated three – way vacuum valve controls the opening and closing of the pilot valve through electromagnetic force or other external forces, thereby affecting the working state of the main valve. In a vacuum system, when it is necessary to change the gas flow direction, adjust the gas flow rate, or cut off/connect the pipeline, a signal is applied to the pilot valve. The pilot valve opens or closes, guiding the control gas flow into different chambers of the main valve, pushing the main valve core to move, and realizing different connection states among the three channels, so as to meet the vacuum control requirements of the system.

Structural Design

Valve Body Material: It is made of anodized aluminum, which is lightweight and corrosion – resistant. It can adapt to a variety of working environments, prolonging the service life of the valve.
Valve Core Components: The two valve cores are made of Vulkollan® and installed on a stainless – steel rod. This material has good wear – resistance and sealing performance, which can effectively reduce internal friction and dynamic stress, ensuring the stable operation of the valve.
Diaphragm and Spring: It is equipped with a diaphragm made of special material for servo – control and a thrust spring for the reciprocating motion of the valve core. The diaphragm can accurately control the movement of the valve core, and the thrust spring ensures the rapid reset of the valve core after action, enabling the valve to respond quickly.

Technical Parameters

Working Pressure: 0.5 to 3000 mbar abs, which can work stably within a wide pressure range.
Servo – Control Pressure: There is a specific table for reference, and the appropriate parameters need to be selected according to the specific working conditions.
Suction Fluid Temperature: – 5℃ to + 60℃. There are certain restrictions on the temperature of the suction fluid to ensure that the performance of the valve is not affected within this temperature range.
Valve Port Diameter: The port size is G1/4", and the throttle hole size is 8.5 mm.
Flow Rate: The maximum flow rate is 3.5 scfm (cubic feet per minute) or the equivalent flow unit.
Vacuum Level: It can reach a vacuum degree range of 0.39 – 29.91 (1000 – 0.5).

Features

Fast Response: The unique structural design enables the valve to open and close quickly, realizing the rapid control of the vacuum system, and meeting the system's requirements for quickly introducing air or cutting off the air flow.
Long Service Life: Due to the reduction of internal friction and dynamic stress, the wear of each component of the valve is small, which prolongs the overall service life of the valve and reduces the maintenance cost.
Good Sealing Performance: High – quality sealing materials and advanced sealing structures are adopted to ensure that the valve can maintain good sealing performance under different working conditions, prevent gas leakage, and ensure the stability of the vacuum system.
Compact Structure: The overall structure is designed compactly, occupying a small space, which is convenient for installation and integration into various vacuum systems, improving the space utilization rate of the system.

Application :

It is mainly used in occasions where a rapid exchange between the suction port of the vacuum pump and the loop intake is required to quickly restore atmospheric pressure, such as vacuum coating equipment, vacuum drying equipment, semiconductor manufacturing equipment, laboratory vacuum systems, etc. In these fields, it can accurately control the vacuum degree and gas flow direction, ensuring the normal operation of the equipment and the stability of the process.
