Our Butt Weld Steel Pilot Valve is designed for precise control in ammonia and Freon-based refrigeration systems. Engineered with high-strength steel and built to withstand harsh industrial environments, this pilot valve offers superior durability, corrosion resistance, and leak-tight performance.
Material: High-grade carbon or stainless steel (customizable)
Connection Type: Butt welding for permanent, high-pressure applications
Medium: Compatible with NH₃ (ammonia), Freon (R22, R134a, R404A, etc.)
Application: Cold storage, industrial refrigeration, HVAC, chemical processing
Temperature Range: -50°C to +150°C
Pressure Rating: Up to 4.5MPa (customizable options available)
Certification: CE, ISO9001 (on request)
Precision flow control for refrigeration systems
Designed for high-efficiency cooling performance
Reliable sealing and low maintenance
Suitable for continuous operation in demanding environments
Technical parameters：
Nominal pressure: 2.8MPa Applicable temperature:-50℃～+150℃
Test pressure: 4.2MPa Applicable medium:ammonia,fluorine,etc.
Characteristics:
- The Pilots ACVC are used as downstream 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 valves.
- The Pilots ACVC working by a range of pressure regulation of 0.5 Bars to 7 Bars.
- Turning the regulating spindle clockwise to increase the opening pressure of the
pilot,(For exmple the suction pressure) and it decreases when we turn the spindle
anticlockwise.
- ACVC combines AM main valve to regulate maximum suction pressure,such as
crankcase pressure of compressor.
- The reference pressure must be connected to the low pressure side of the system.
