Hydraulic Pressure Regulator Pilot Valve – Differential Pressure Control for Refrigeration Systems

Introduction:

The ACVPP series hydraulic pressure regulator pilot valve is engineered for precise differential pressure control in refrigeration systems. Designed to maintain a constant pressure difference between the AM1 or AM3 main valves and the ACVPP reference pressure, ensuring optimal system performance.

Features:

• Material: Carbon Steel

• Temperature Range: -50°C to +120°C

• Pressure Range: 0–10 bar

• Mounting Options: Directly over AM1 or AM3 main valves; externally on CVH housing valves

• Adjustment: Manual spindle for precise differential pressure setting

• Standards Compliance: DIN, GB, ANSI

Applications:

• Industrial refrigeration systems

• HVAC systems

• Ammonia and fluorine-based refrigeration circuits

• High-temperature and high-pressure environments

Advantages:

• Enhanced system stability and efficiency

• Durable construction for extended service life

• Easy integration with existing valve setups

• Reliable performance across a wide temperature and pressure range

Technical parameters：

Nominal pressure: 2.8MPa    Applicable temperature:-50℃～+150℃

Test pressure: 4.2MPa            Applicable medium:ammonia,fluorine,etc.

Characteristics:

- The Pilots ACVPP are used as differential pressure regulators, mounted directly  over main 

   valves AM1 or AM3. They can be also mounted on a housing valve

   CVH in an external line to control one or more AM or RAK valves.

- The Pilots ACVPP working by differential pressure with a range of 0 Bars to 10 Bars.

- Turning the regulating spindle clockwise to increase the opening differential
   pressure of the pilot,(thus the evaporating pressure and temperature)and it 

   decreases when we turn the spindle anticlockwise.

- Pilot valve is used to keep the difference between AM inlet pressure and 

   ACVPP reference pressure constant.
