FAQ– Reversing Valve for Heat Pump
Q1: What is a 4-way reversing valve in HVAC systems?
A: It’s a directional control valve that switches refrigerant flow between heating and cooling cycles in a heat pump. The 4-way design allows efficient flow reversal with minimal pressure loss.
Q2: What does a reversing valve do in a heat pump? A:
A: The reversing valve allows a heat pump to reverse the refrigerant direction, turning the system from cooling to heating mode or vice versa.
Q3: Does KAK provide custom reversing valve solutions?
A: Yes. KAK specializes in OEM and custom-designed reversing valves. We can adjust specifications such as connection sizes and capacities to meet your specific system requirements.
Q4: Do you offer solenoid coils with reversing valves?
A: Yes, KAK supplies reversing valves with integrated or separate solenoid coils and contactors for OEM heat pump applications.
Q5: Are KAK valves compatible with different HVAC systems?
A: Our valves are designed with versatility in mind. Beyond standard models, we offer extensive customization services to ensure perfect integration with various industrial and residential HVAC/R configurations.
