Product Name：York 025-40900-001 Expansion Valve
Core Features
1. Advantage：
This YORK expansion valve (P/N 025-40900-001) is a thermostatic expansion valve that meters liquid refrigerant into the evaporator based on superheat at the outlet. The brass valve body carries the inlet/outlet ports and the adjustable superheat setting, while the capillary tube connects the remote sensing bulb to the diaphragm. The bulb must be strapped firmly to the evaporator suction line for accurate superhead control. A failing TEV causes either starved evaporators (high superheat, poor cooling) or flooded evaporators (low superheat, compressor floodback).

3.Our Advantage
TEV replacement requires matching the correct capacity, refrigerant, and superheat setting-using the wrong valve causes poor evaporator performance regardless of how well installed it is. We supply the original YORK valve matched to your chiller circuit. When installing, strap the bulb to a clean horizontal suction line, insulate it well, and set superhead per the manual. If your chiller shows errating superheat or poor capacity, this valve is a prime suspect.

Q: 2 Q: How do I install the remote bulb?
A: A:Strap the bulb firmly to a clean, horizontal section of the suction line near the evaporator outlet, insulate it from ambient temperature, and orient it per the service manual. Poor bulb contact is the most common cause of inaccurate TEV operation.
Q: 3.: What refrigerant does this valve work with?
A: This valve is factory-charged and calibrated for the specific YORK circuit it was ordered for. Confirm your chiller's refrigerant type matches before ordering.
