## Product Summary

HVFF pneumatic hand valve is a **push-to-connect 2-way manual air shut-off valve** designed for airflow control and pressure release in pneumatic systems.

Unlike standard shut-off valves, the HVFF series features a **venting (exhaust) function**, allowing residual air pressure to be released when the valve is turned off. This improves system safety and maintenance efficiency.

With a compact structure and quick push-in connection, it is widely used in industrial automation, air control systems, and pneumatic pipelines.

**OEM and ODM customization services are available** for tube size, structure, sealing materials, and branding requirements.
