Steel Ammonia Refrigeration Compressor Control Valve

Product Overview

The Steel Ammonia Control Valve (J65F/JH65F/L65F Series) is a heavy-duty fluid control solution engineered exclusively for ammonia-based refrigeration systems. Manufactured by Liyongda, this through-way globe valve adheres to ANSI standards, featuring a robust cast steel construction designed to withstand high pressure (PN40) and extreme temperatures. With a diameter range of DN15 to DN300, it caters to diverse system sizes—from small commercial units to large industrial facilities. The valve’s specialized design ensures precise ammonia flow control, critical for maintaining safety, efficiency, and stability in refrigeration applications where ammonia is the primary refrigerant.

Core Features

ANSI-Standard Construction for Global Compliance

Built to ANSI standards, the Steel Ammonia Control Valve meets strict international quality and safety requirements for ammonia refrigeration. This compliance simplifies regulatory adherence and ensures compatibility with global refrigeration equipment.

Durable Cast Steel Material

Crafted from high-grade cast steel, the valve offers exceptional corrosion resistance and structural integrity under PN40 pressure. Cast steel’s durability minimizes wear in continuous operation, extending service life and reducing replacement costs.

Through-Way Globe Valve Design for Precision Control

The through-way structure enables accurate modulation of ammonia flow, preventing surges and maintaining stable system pressure. This precision optimizes refrigeration efficiency, making it ideal for temperature-sensitive applications like food processing and cold storage.

Wide Diameter Range for Versatility

Available in DN15 to DN300, the series covers flow requirements from small restaurant refrigerators to large industrial cold storage facilities, eliminating the need for multiple valve types across projects.

Ammonia-Specific Sealing Technology

Engineered with leak-proof seals tailored for ammonia, the valve prevents hazardous gas leakage, ensuring workplace safety and environmental protection while preserving system pressure integrity.
