CVP-L Pressure Control Pilot Valve for Industrial Refrigeration Systems
The ACVP-L pressure control pilot valve is a reliable mechanical control component designed for industrial refrigeration systems. It is used to regulate and maintain constant pressure on the inlet side of a main valve, ensuring stable system operation and preventing pressure fluctuations.
This pilot valve is commonly installed on the top cover of main valves such as AM3A and ICS3, providing precise pressure regulation in refrigeration systems using ammonia, Freon, CO₂ and other refrigerants.
With a wide adjustable pressure range and strong resistance to low temperatures, the ACVP-L valve is widely used in cold storage, food processing plants, and large-scale refrigeration installations.
What Is an ACVP-L Pressure Control Pilot Valve?
Pilot Valve for Refrigeration Pressure Control
The ACVP-L pilot valve is a mechanical pressure control device that regulates the opening and closing of a main refrigeration valve.
Its main purpose is to:
Maintain stable inlet pressure
Automatically regulate system pressure
Protect refrigeration equipment from pressure fluctuations
When the system pressure exceeds the preset value, the pilot valve activates the main valve to adjust flow and restore the desired pressure level.
This makes the ACVP-L an important component for safe and efficient refrigeration system operation.

Key Features of ACVP-L Refrigeration Pilot Valve
1. Mechanical Control for Main Valves
The ACVP-L pilot valve is designed for mechanical control of refrigeration main valves, ensuring reliable performance without complex electronic systems.
2. Direct Installation on Main Valve Cover
The valve can be installed directly on the top cover of main valves such as AM3A and ICS3, allowing easy integration into existing refrigeration systems.
3. Constant Pressure Regulation
The pilot valve maintains stable pressure at the inlet side of the main valve, helping prevent system instability caused by pressure fluctuations.
4. Multiple Functional Applications
When installed in an ACVH valve housing, the ACVP-L can be used as:
A constant pressure valve
A pressure relief valve
This versatility allows the valve to adapt to different refrigeration system designs.
5. Wide Adjustable Pressure Range
ACVP-L pilot valves are available with adjustable pressure settings ranging from:
−0.65 bar to 10 bar
This makes the valve suitable for various industrial refrigeration applications.
