Proportional valves: dynamic flow regulation
Proportional valve solutions go beyond simple components. They respond dynamically to input signals and maintain stable
performance, even under changing pressure. Perfect for precise dosing for oxygen delivery in medical devices, or stable sampling in gas analysers. We can deliver customised valve solutions that make
your product smarter and more competitive. We deliver complete systems, such as valves, driver electronics, and
sensors, that enable closed-loop flow regulation for unmatched accuracy.
P447HF _Hi Flow Proportional Valve : The P447HF has been designed for mixing oxygen, air or other gases with high precision. High speed and sensitive regulation of the valve make it ideal for gas dosing up to 200 l/min @ 2.4 bar
P447BP Proportional Mixing Valve : P447BP is a proportional valve with a venturi for mixing applications. It is ideal for applications with high back pressure, such as mixing gases in a tank, piloting venturi injectors for high-flow applications, and regulating pressure membranes.
Flow rate :- up to 140 l/min @ 2.4bar
P337CFR Precision Proportional Pilot Dosing Valve : The P377CFR is the perfect choice for precision blending, CPAP or ventilation valves with high back pressure. The P337 can pilot a pressure regulator valve or generate an air jet to create the required lung pressure. Due to its small footprint and accurate, fast response time (<5ms), it is a versatile solution. Available in flows from m1/min up to 80l/min range, supporting pressures up to 12 bar.
P261 High Flow Ventialor Valve : The P261 delivers upto 300 l/min flow. The robust construction is ideal for forced ventilation delivering a repeatable flow profile.
P357 Proportional Dosing Valve : 2/2NC valve for 02 valve block. This valve is a perfect solution for dosing in either forced or assisted mode, extra O2 for patients requiring extra 02 dosage higher than air. The valve can be mounted onto a manifold in series to limit the number of 02 bottles. The flow rate matches the required need of 02.
Constant Flow Regulators (CFR)
The constant flow regulator is designed to deliver consistent flow or pressure in demanding environments, without the complexity or cost of traditional mass flow controllers. Developed for design engineers in the medical and analytical device industries, the CFR offers a streamlined solution that combines high performance with ease of integration.
The CFR merges a precision proportional valve, a high-accuracy pressure sensor, custom control electronics and an advanced control algorithm. This synergy enables stable flow regulation across varying conditions, while maintaining the accuracy and responsiveness expected from far more elaborate systems.
By simplifying the control architecture, the CFR reduces system complexity and cost, while enhancing reliability. Its compact design and integrated functionality make it ideal for OEMs seeking to optimise space, performance and interface simplicity.
