The RVSF-42F25C Industrial Refrigeration Safety Valve is designed to provide reliable over-pressure protection for industrial refrigeration systems. It automatically releases excess pressure when the system pressure exceeds the preset limit, protecting compressors, pipelines, and other equipment from potential damage while ensuring safe and stable operation. The valve is constructed with a WCB body, stainless steel internal components, PTFE sealing parts, and a high-strength 50CrVA spring, providing excellent durability, corrosion resistance, and long-term sealing performance. It supports nominal diameters from DN15 to DN50 and operates effectively within a temperature range of −40°C to 150°C. The RVSF-42F25C series is suitable for working media such as refrigerants, oil, and water, and is widely used in industrial refrigeration plants, cold storage systems, and large-scale cooling equipment where dependable pressure relief and system safety are essential.
