Electrically-actuated valve WL2832

electricflow controlpressure-reducing

Product Summary
The WL 2832 proportional air valve is engineered for precise airflow and pressure control in medical devices. Adjustable via solenoid current, it provides smooth, infinitely variable regulation with fast response and consistent repeatability. Designed for respiratory systems, diagnostic equipment and medical automation, WL 2832 units are available in standard and customized configurations to support OEM integration and regulatory compliance.

Product Overview
Proportional valves convert an analog electrical signal into a proportional pneumatic output, enabling fine control of flow and pressure. In medical air management, this capability improves patient ventilation profiles, testing accuracy and automated system stability. The WL 2832 bridges binary solenoid control and high-end servo valves, offering precise control with simplified installation and tuning for compact medical equipment.

Main Features

• Infinite positioning: stepless modulation of flow and pressure.
• Electro-proportional control: output follows an analog input signal.
• Reduced mechanical shock: smoother actuator acceleration and deceleration.
• Energy efficiency: delivers only required flow/pressure to optimize power use.
• Integrated electronics: available onboard or as a separate control module for easy setup.
• Multiple functions: options for directional, pressure relief, flow control or combined functions.
• Compact design: suited to confined spaces in medical devices.

Advantages / Disadvantages

• Advantages: improved control of flow/pressure for better clinical performance; consolidates functions to simplify system architecture; energy and noise reduction; programmable response for OEM applications; cost-effective alternative to servo valves for many tasks.
• Disadvantages: higher cost than on/off solenoids; requires clean air (filtration often 10 µm or finer); needs driver/amplifier and signal conditioning; continuous power may generate heat; performance below that of high-end servo valves in specific precision or dynamic-response cases.

Applications

• Medical: ventilators, anesthesia machines, respiratory therapy devices, diagnostic systems, medical automation and OEM assemblies.
• Industrial: hydraulic and pneumatic motion control, test stands, injection molding (where applicable).
• Mobile & OEM: compact proportional control for mobile equipment and bespoke OEM solutions.
