Tameson has numerous options for proportionally controlled solenoid valves. A proportional solenoid valve allows a user to accurately control the fluid flow rate with a very fast response, rather than just completely open or close the valve. By continuously regulating the fluid flow rate, you can subsequently adjust process parameters, such as fluid level, pressure and temperature. Proportional control solenoid valves have a slightly different design compared to standard solenoid valves to enable precise and stable positioning of the plunger. The preferred method to control a proportional solenoid valve is by utilizing a pulse width modulation (PWM) signal, which controllers like the Burkert 8605 and 8611 are capable of. By utilizing a controller designed for usage with proportional solenoid valves, you have greater control, less hysteresis, and the ability for a closed loop feedback system (depending on controller inputs) compared to other control methods. Our range of proportional controlled solenoid valves include a wide size selection, multiple options for housing and seal material, and varying pressure ratings. It is important to ensure that the material can withstand the media characteristics and that the valve is sized properly from a pressure and Kv standpoint.
