DAC Worldwide’s ACR Thermostatic Expansion Valve Cutaway, Fixed-Type (373-521) is a professionally-crafted, sectioned example of a common fixed, externally-equalized, thermal expansion valve used in refrigeration and air-conditioning systems for basic metering applications.

The ACR Thermostatic Expansion Valve Cutaway, Fixed-Type is only one of DAC Worldwide’s expansive HVAC training cutaways, which includes an ACR Solenoid Valve Cutaway (373-502), a Heat Pump Reversing Valve Cutaway (373-505), and ACR Magnetic Check Valve Cutaway (373-510), a Condenser Pressure Control Valve Cutaway (KVR) (373-519), and more!

2017年12月15日 · A thermostatic expansion valve (TXV) (see Figure 1) is a refrigeration and air conditioning throttling device that controls the amount of refrigerant liquid injected into a system’s evaporator—based on the evaporator outlet temperature and pressure—called the superheat.

Long lasting and field proven stainless steel diaphragm and welded element construction. Large flat diaphragm permits precise valve control. Field replaceable elements on all standard …

how a TXV regulates flow in response to changing superheat. Starting from the origin, no change in valve stroke occurs as the superheat slowly increases. It is not until the static setpoint is reached that the valve begins to open. From this point forward, further increase in superheat results in a proportional Figure 1 In a TXV, the forces
