## Product Summary

HVSS pneumatic hand valves are manual control valves designed to switch airflow on and off in pneumatic systems.

With an inline structure and push-to-connect design, HVSS valves allow quick installation directly into tubing lines, making them ideal for compact pneumatic layouts and easy operation.

The valve uses a simple handle mechanism to control airflow, enabling fast shut-off and system isolation during maintenance, testing, or emergency situations.

Nickel-plated brass construction and internal sealing components ensure corrosion resistance, durability, and long service life in industrial environments.

OEM and ODM customization services are available for thread type, tube size, and branding requirements.

### Key Features

- Manual handle for airflow ON/OFF control

- Inline structure for direct installation in tubing

- Push-to-connect quick connection

- Available in 2-way and 3-way configurations

- Nickel-plated brass body for durability

- O-ring sealing ensures leak-resistant performance

### Applications

Pneumatic automation systemsUsed for manual control of air supply and actuator operation

Air supply shut-off systemsProvides quick isolation of airflow for maintenance

Industrial machineryEnsures safe operation and emergency stop capability

Testing and maintenance circuitsAllows temporary control of air flow during system checks

Compact pneumatic installationsIdeal for inline installation in limited spaces

### Product Function

HVSS pneumatic hand valves are used to manually control airflow in pneumatic systems.

- **ON state:** Allows air to pass through the system

- **OFF state:** Blocks airflow

For 3-way valves, the system can also **release residual pressure**, improving safety during maintenance and repair.

Compared to automatic valves, HVSS provides simple, reliable, and direct manual control for air circuits.
