The RVSF-22C300P Series Safety Valve is designed to provide reliable over-pressure protection in refrigeration and HVAC systems. It automatically releases excess pressure to prevent damage to pipelines, vessels, and system components, ensuring safe and stable operation. The valve features a durable CF8 stainless steel body, PTFE sealing components, and a high-strength 50CrVA spring, offering excellent corrosion resistance and long service life. This safety valve supports nominal pressures up to 5.0 MPa and is suitable for a wide range of refrigerants, oil, water, and other compatible media. It operates effectively within a temperature range of −40°C to 150°C and provides accurate pressure relief with minimal leakage. The RVSF-22C300P series is widely used in refrigeration units, air-conditioning systems, heat pump equipment, and industrial cooling systems where dependable pressure protection is required.
