Flowserve Atomac ARV/SG PFA lined check valve with sight glass DN 25

PFA lined ball check valve with sight glass DN 25

The ARV/SG sight glass with an integrated check valve is designed for reliable flow control in horizontal and vertical piping systems, offering maximum compatibility and easy installation with a DIN EN 1092-2, PN16 flange connection and face to face length per DIN EN 558 (Series 1). Its PFA-lined ductile iron EN-JS 1049 (GGG40.3) body and flange provide exceptional chemical resistance and corrosion protection. The borosilicate glass (DIN 7080) ensures high transparency and long-term durability, while the PTFE solid ball effectively prevents backflow, ensuring a safe and efficient flow process.

Also available with flange connection acc. to ASME Class 150 on request.
