Van Wezel 82001325 Regulator: Precision Expansion for Modern HVAC Systems

The Van Wezel 82001325 Regulator is a high‑performance expansion valve designed to deliver optimal refrigerant flow and pressure control in air conditioning and refrigeration applications. Engineered with advanced materials and precision manufacturing, this component ensures reliable operation across a wide range of temperatures and pressures.

Key Functional Characteristics

• Type: Thermodynamic expansion valve (TEV) – automatically adjusts refrigerant flow based on evaporator temperature.
• Operating Range: Suited for low‑pressure systems, typically from -10 °C to +30 °C operating temperatures and pressures up to 4 bar.
• Flow Capacity: Adjustable between 0.5 kg/h and 3.5 kg/h, allowing fine tuning for varying system loads.
• Control Mechanism: Internal diaphragm and spring assembly provide precise pressure differential control.

Construction & Materials

The regulator features a stainless steel body (316L) to resist corrosion in humid or chemically aggressive environments. The internal components are fabricated from phosphor bronze, offering excellent wear resistance and dimensional stability under thermal cycling.

Sealing & Gaskets

All connections employ PTFE (Teflon) gaskets to ensure leak‑free performance. The valve body incorporates a rubber O‑ring seal that maintains integrity over extended service periods.

Installation Guidelines

1. System Preparation: Ensure the refrigerant circuit is depressurized and all safety protocols are observed before handling the regulator.
2. Mounting Orientation: Install with the valve body facing upward to facilitate proper refrigerant flow; verify that the inlet and outlet ports align correctly with the system piping.
3. Tightening Sequence: Use a torque wrench set to 0.8 Nm for all threaded connections, preventing over‑tightening which could damage seals.
4. Leak Testing: After installation, perform a pressure test at the specified operating pressure and inspect for any signs of leakage around the valve body and gasket interfaces.

Compatibility & Application Scope

The Van Wezel 82001325 Regulator is engineered to work seamlessly with a variety of refrigerants, including:

• R-134a
• R-410A
• R-407C
• R-32

Its compact design makes it suitable for residential, commercial, and automotive HVAC systems. The valve’s robust construction also allows integration into high‑efficiency heat pump units and industrial refrigeration loops.

Performance Benefits

• Energy Efficiency: By maintaining optimal refrigerant flow, the regulator reduces compressor cycling, leading to lower energy consumption.
• System Longevity: Precise pressure control minimizes wear on downstream components such as condensers and evaporators.
• Thermal Stability: The valve’s materials retain dimensional accuracy across temperature swings, ensuring consistent performance.

Troubleshooting & Maintenance Tips

1. Reduced Cooling Capacity: Check for refrigerant leaks or blockage in the inlet line; verify that the regulator is not stuck in a closed position.
2. Unusual Noise: Inspect the valve body for debris or foreign objects that may interfere with diaphragm movement.
3. Frequent Pressure Fluctuations: Ensure the spring tension has not been altered; replace if necessary to restore proper pressure differential.
