The ESVB is a direct driven expansion valve that uses a stepper motor to actuate the valve pin. The stepper motor uses a voltage pulse to move the valve either open or closed, one step for each pulse. The ESVB has the ability to be interfaced with a variety of control electronics. The ESVB is useful in a variety of applications ranging from case control to subcooler applications, truck/trailer refrigeration, and heat pump/air conditioning applications.

• Hermetic construction eliminates external leakage

• Bi-Flo capability allows one valve to control the superheat in both cooling and heating modes for heat pump applications

• Stepper motor moves in discrete "steps" allowing for precise digital control

• Voltage is required only when moving the valve increasing energy efficiency

• Removeable external connector for easy replacement

• Contains internal strainer in both the inlet and outlet connections to protect the valve from contamination in both forward and reverse flow modes

• Solenoid-tight shut off eliminates the need for both a traditional TEV and a solenoid valve in the liquid line

• Stainless steel housing minimizes corrosion over the life of the valve

• 2-phase bi-polar, linear actuating stepper motor, direct drive

• Two motors available 24 volt or 12 volt alternating square wave
