Proportional Valves | Flow & Pressure Control Valves

Proportional pressure control valves, including directly or indirectly controlled and pilot valves, are crucial for managing and compensating for dynamic variations in the control chain. They ensure that pressure remains below the upper operational limit, featuring short response times and adjustable parameters to meet specific media or application requirements. Additionally, they support low energy consumption to align with efficiency and sustainability goals.

Proportional control valves regulate and adjust fluid flow, pressure, and direction in hydraulic systems. These valves respond to changes in electrical input, modifying output accordingly. They use a closed-loop system managed by electrical inputs from sensors, functioning as direction control valves or pressure control valves.

Working Principle

When an external signal reaches the device, electrical currents flow to the valve drive, ultimately moving the spool and creating a fluid path. The coils within the valve carry varying voltages, producing a proportional force that shifts the spool accordingly.

Proportional valves provide a smooth and continuous variation in flow or pressure in response to electrical input, delivering high-performance, precise, and stable pressure adjustments quickly.

Applications

Proportional valves are utilized in various applications, including:

• Basic machinery processes
• Hydro-pneumatic systems
• Tensioning and spraying
• Analytical instrumentation
• Spot welding, tire balancing, PET blowing
• Press systems and molding machines
• Flight simulators, airframe testing, etc.

• Directional control valves
• Pressure control valves
• Flow control valves

At Shri Ank Enterprise, we provide hydraulic proportional valves from the Hydrank brand, serving as direct replacements for Yuken brand valves. Contact us to discuss your requirements for the tubular check valve. Our experienced sales team is ready to help you identify the best options for your needs.

These valves utilize dual electrical loops to control system pressure and flow, using minimal pressure drops to monitor load pressure, thus conserving energy and managing pump pressure effectively. They are interchangeable with Yuken’s EFBG valves and offer two pressure settings for precise operations.

The Hydrank EDG series excels in managing hydraulic system pressure, replacing Yuken EDG valves. Available with two pressure settings, these valves operate with high accuracy and stability.

When selecting proportional control valves, consider factors such as flow and pressure, system operating temperature, and required reverse sensitivity. By choosing Shri Ank Enterprise, you can trust in the quality, standards, and cost-effectiveness of our products.
