Disco non-return valve for high pressure
The RV120 high-pressure non-return valve from FERGO is specially designed for reliable backflow protection in industrial high-pressure applications. This high-performance check valve has an overall length in accordance with DIN EN 558 series 52 and is designed for installation between flanges PN63/PN100 and ANSI 600/900. With its corrosion-resistant construction, available in stainless steel or super duplex, the high pressure check valve is suitable for tight installation spaces and demanding environments.
The high pressure non-return valves are available with different sealing materials, including NBR, EPDM, FKM, PTFE and even metallic options. The valves fulfil numerous international approvals and conformities such as DVGW, FDA, REACH, RoHS and WRAS. Depending on the material and design, they can withstand temperatures from -200 °C to +450 °C. Thanks to their impressive performance, they are ideal for applications in the chemical, food, water and energy industries.
