Products
The RVSF-22C300T Series Safety Valve is designed to protect refrigeration and HVAC systems from excessive pressure by automatically releasing pressure when it exceeds the preset limit. This ensures safe and reliable operation of compressors, pipelines, and other system components. The valve features a durable HPb59-1 brass body, PTFE sealing components, and a high-strength 50CrVA spring, providing excellent sealing performance, corrosion resistance, and long service life. With a nominal pressure of up to 5.0 MPa and a working temperature range of −40°C to 150°C, the valve is suitable for various working media such as refrigerants, oil, and water. The RVSF-22C300T series offers stable pressure relief performance and is widely used in refrigeration units, air-conditioning systems, heat pumps, and industrial cooling equipment where reliable pressure protection is essential.
