Easy to operate: the manual control mode is adopted, without complex electrical equipment or air source treatment device, the staff can directly realize the on-off control of the gas path through manual operation, and can flexibly control the flow direction and on-off state of the gas according to the actual needs, the operation process is simple and intuitive, which is convenient for on-site personnel to operate and adjust, especially for the occasion that frequent manual control of the gas path is required.
Compact structure: the overall structure design is relatively small and lightweight, which will not occupy too much space during installation, and can well adapt to a variety of different installation environments, especially suitable for equipment and places with relatively compact space, which is convenient for installation, layout and use, can effectively save installation space, improve space utilization, and is also convenient for layout and installation in some complex pneumatic systems.

Strong versatility of specifications: The specification design of "1212" enables its interface size to be well matched with a variety of common pneumatic lines and components, and has strong versatility. This makes the hand valve can be easily used in all kinds of pneumatic systems, can be combined with other pneumatic equipment, to meet different pneumatic control needs, whether in small pneumatic devices or large industrial pneumatic systems, can play a good role, reduce the installation and use of trouble caused by the mismatch of different equipment interfaces.

Excellent material: generally made of high-quality materials, such as nickel plating on the surface of copper. This material has good anti-corrosion and anti-pollution performance, can maintain stable performance in different working environments, and is not easily affected by corrosion and pollution, thereby prolonging the service life of the hand valve, reducing maintenance costs, reducing downtime and economic losses caused by equipment failure and maintenance, and can be applied to some harsh working environments.

Good sealing: The threaded end comes with PT thread glue, which can effectively seal the threaded connection and prevent gas leakage. Good sealing performance is the key to ensure the normal operation of the pneumatic system, which can reduce the energy loss and system failure caused by gas leakage, improve the stability and reliability of the system, ensure the stable and efficient operation of the pneumatic system, and reduce the safety hazards and production costs caused by gas leakage.
