High Speed 200 Bar Proportional Control Valve
Pressure Balanced Motor Actuated Valve – DN25 & DN40
This new generation 200 bar proportional control valve has been engineered for high-speed, high-pressure applications where precise and rapid control is critical.
Designed with a pressure-balanced piston system to reduce mechanical stress during operation, this valve delivers exceptional performance in demanding environments such as aerospace testing, high-pressure gas systems and advanced industrial process control.
Available in DN25 and DN40 sizes, the valve combines 316L stainless steel construction with PTFE sealing materials and a high-speed motor actuator capable of extremely fast response.
Why this valve is different
→ Pressure-balanced piston design for reduced stress and improved durability
→ Ultra-fast response time – full stroke in approx. 150 ms
→ Rated for pressures up to 200 bar
→ Motor actuated for proportional control
→ 316L stainless steel body
→ PTFE valve and seal materials
→ Designed for dynamic, high-performance applications
→ Suitable for test environments and advanced control systems
Ultra-fast proportional control – 150 ms response
This valve is designed for applications where response speed matters.
With a full stroke time of approximately 150 milliseconds, it enables rapid adjustment of flow or pressure, making it ideal for:
→ Aerospace testing facilities
→ Dynamic pressure control systems
→ Gas flow simulation and control
→ High-speed test rigs
→ Research and development environments
This level of response is significantly faster than typical motor actuated valves, placing it in a specialist performance category.
Pressure-balanced design for reduced stress
The internal piston is being optimised with a pressure-balanced design to:
→ Minimise actuation forces
→ Reduce internal stress during opening and closing
→ Improve reliability and service life
→ Deliver smoother proportional control
This is especially important in high-pressure systems, where conventional designs can suffer from uneven loading and accelerated wear.

316L stainless steel and PTFE construction
The use of 316L stainless steel provides excellent resistance to corrosion and mechanical stress, while PTFE sealing materials offer chemical compatibility and low friction performance.
Together, these materials ensure reliable operation in demanding conditions.
DN25 and DN40 options
Two sizes are available to suit different system requirements:
→ DN25 – compact high pressure control
→ DN40 – increased flow capacity for larger systems
Engineered for precision and speed
This is not a standard isolation valve.
It is a high-performance proportional control solution designed for:
→ rapid response
→ precise control
→ high pressure environments
If your application requires fast, accurate control under demanding conditions, this valve offers a unique solution.
