The 4H series hand-operated valve is a manual directional control component designed specifically for industrial pneumatic systems, mainly used for precise switching of the supply and exhaust paths of double acting cylinders or other actuating components
Its core functional features are as follows:
Reliable and precise operation
Adopting an intuitive manual driving method, the valve stem actuation process is smooth, with clear and precise positioning, ensuring the accuracy of switching actions and a sense of operational reliability
Flexible hand response, suitable for situations that require frequent manual control
Compact sealing structure
The core sliding column valve core design combined with a refined sealing scheme effectively isolates internal leakage, and the sealing ring adopts high-quality products to ensure product sealing.
The overall structural layout is exquisite, lightweight, and convenient for daily maintenance and disassembly
Long term low resistance operation
The key inner hole channels are treated with specific surface treatment methods, significantly reducing the frictional resistance of internal moving parts
Aluminum alloy valve body is wear-resistant and has a long service life. The resistance between the axis and the valve body is small, and the service life can reach 5 million times
Maintenance free oil supply
In terms of design, there is no need to rely on external oil supply, simplifying the usage process and reducing the requirements for subsequent maintenance
Convenient installation and adaptation
Providing panel installation function simplifies the series integration process and makes installation simple and stable.
Diverse interface sizes (such as G1/8, G1/4, etc.), suitable for different application scenarios
Application scenarios
Widely used in industrial fields such as food machinery and equipment, fire-fighting equipment, and automated production lines
Some models (such as 4H230C-06) support three position five way function, suitable for more complex control requirements
