For automatic and remote control of high-pressure fluid systems in extreme working environments.
The High Pressure Pneumatic Needle Valve is an automatic control valve designed for precise opening and closing of high-pressure fluid or gas pipelines. Powered by a pneumatic actuator and controlled via an electromagnetic directional valve, it enables reliable remote or automated operation in high-pressure and ultra-high-pressure systems.
This valve is widely used in high-pressure equipment where safety, stability, and precise flow control are required.
The Highlight high pressure pneumatic needle valve integrates a high-performance pneumatic actuator with a straight-through needle valve structure. The actuator cylinder is driven by an electromagnetic directional valve, allowing the valve needle to move vertically in a straight line to open or close the flow path.
Designed for automated and remote control applications, this pneumatic needle valve is suitable for both high-pressure and ultra-high-pressure operating conditions. It delivers long service life, simple operation, and a high safety factor, even in extreme environments such as ultra-high pressure, low temperature, or fluctuating working conditions.
Available interface specifications include ZG1/4 and M14 × 1.5, making it compatible with various high-pressure systems.
| Rated Working Pressure PSI (bar) | Interface Specification | Diameter (mm) | Control Mode | Driven Air Pressure PSI (bar) | Through Valve Model |
| 10,000 (690) | ZG1/4″ | 2.7 | Double-acting pneumatic control | 40–116 (2.75–8) | GCHV70M1S |
| 60,000 (4140) | ZG1/4 × 1.5 | 2.7 | Double-acting pneumatic control | 40–116 (2.75–8) | GCHV400M1S |
The pneumatic needle valve can be installed in panel-mounted or system-integrated configurations. It is designed for easy connection with pneumatic control systems and high-pressure pipelines, allowing seamless integration into existing automated equipment.
For instrument and process systems requiring controlled pressure venting, safe isolation, and reliable atmospheric discharge during maintenance or calibration procedures.
For precision pressure isolation, flow control, and instrument protection applications requiring reliable shut-off performance and long-term sealing integrity under high pressure and wide temperature ranges.
For precise flow control and reliable shut-off in ultra-high pressure gas and liquid systems, suitable for extreme pressure and temperature operating conditions.
