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.

FAQ
Q1: What is an HVSS pneumatic hand valve?
It is a manual valve used to control airflow on and off in pneumatic systems.
Q2: What is a pneumatic hand valve used for?
It is used to start, stop, or isolate air flow in pneumatic circuits.
Q3: What is the difference between 2-way and 3-way hand valves?
2-way valves only open/close airflow, while 3-way valves also release residual pressure for safety.
Q4: Can HVSS valves release pressure?
Yes, 3-way HVSS valves can discharge residual pressure when turned off.
Q5: What tubing is compatible with HVSS valves?
HVSS valves are suitable for PU and nylon tubing.
Q6: Can HVSS valves be customized?
Yes, OEM/ODM customization is available for size, thread type, and configuration.
