Model E40W – Actuated – Hot/Cold Water Mixers – Emech™ Digital Control Valves


The 3-port
mixing valve utilizes ceramic shear action disc technology to provide
tight shut-off, high pressure differential capability, and long life
integrity. Fitted with the electronic actuator and integrated
temperature sensor, the system delivers high performance stand-alone
closed-loop temperature control.

With the temperature feedback signal, the actuator provides
temperature control accuracy to ± 1°F (± 0.5°C) over a 32°F – 212°F (0°C
– 100°C) control range, capable of blending from 0% to 100% of either
inlet temperature. Even with sudden changes of inlet pressure and
temperature to the valve, the actuator controller aggressively minimizes
outlet temperature variations, making the system ideal for use in
industrial applications as a simple stand-alone or integrated mixing
