Proportional Solenoid Valves

The Proportional Solenoid Valve offer the same On/Off control as standard Pilot-Operated Solenoid Valves but with the added functionality to control the flow of water passing over the valve orifice. Proportional control is offered across hot and cold water supplies from 0.5 up to 12 litres per minute within dynamic pressure range from 0.5-10 bar.

Benefits of Proportional Solenoid Valves

Proportional valves are ideally suited for applications in domestic and commercial electrically heated showers for gravity and mains fed water systems, BEAB CARE shower systems, thermostatic mixing valves for gravity and mains fed water systems, and digital thermostatic valve systems for showers and faucets.

The unique features offered by Hydralectric are derived from the use of a pre-tension spring to manage effective opening and closing and larger main spring to provide proportional control. The valve can be controlled using 24VDC power supply or pulse width modulated signal to provide variable control when used in closed loop systems.

Approved to EU Standards

The proportional solenoid valves are approved to EU standard for electrical and safety standards applicable, plus Hydralectric proportional solenoid valves are approved to potable water standards including WRAS (UK) and  ACS (France).

Hydralectric’s range of proportional is extensive with single, double and triple valves supported by single standard plumbing inlet connection. The compact and robust construction using technical polymers to provide safe conveyance and control of water services has been tested up to 50,000 operations in hot and cold water supplies up to 85°C.
