Understanding proportional flow control valves for water systems

A proportional flow control valve for water systems is an electronically controlled, normally closed 2-way valve that continuously adjusts water flow rather than simply switching it on or off. Dolphin Fluidics valves use closed-loop regulation: flow rate is measured in real time and compared against the target set point, so dosing and dispensing remain accurate even under high pressure and varying conditions.

Each valve can interface directly with external pressure, flow or temperature sensors, and consumes up to 20 times less energy than a traditional solenoid valve of equivalent performance.

Need valves for a challenging environment?

Advantages of Dolphin Fluidics proportional valves

Dolphin Fluidics proportional valves are built to outperform conventional solenoid valves on every parameter that matters for water applications: power consumption, noise, precision and integration.

Technical characteristics

The Smart HP Liquid valve is the core Dolphin Fluidics solution for water applications, built around a shape memory actuator and a 32-bit microprocessor for onboard closed-loop control.

• Shape memory actuator for accurate, silent control of valve opening and closing
• 32-bit microprocessor with built-in memory for closed-loop proportional control
• Full-seal gasket ensuring complete medium separation and a high level of hygiene
• Hardware interface for external pressure, flow or temperature sensors

Applications for water-related industries

Proportional water valves from Dolphin Fluidics are used wherever water flow needs to be dosed, mixed or monitored with precision:

• Water treatment — dosing of treatment chemicals and precise flow regulation in filtration and purification systems
• Humidification — accurate water dosing for industrial and HVAC humidification systems
• Food & beverage water dosing — hygienic, drift-free dosing for water-based beverage dispensing and process water
• Medical devices — precision water and liquid handling for diagnostic and medical equipment, supported by NSF/FDA-compliant wetted materials
