VALFTEK Brass Disc Check Valve DN50 PN16
Zero-leak backflow protection with a compact, maintenance-free brass body.
VALFTEK Brass Disc Check Valve DN50 PN16 stops reverse flow in industrial piping with a zero-leak guarantee and a long-life brass body. Moreover, this valve is an ideal solution for preventing backflow in industrial installations. In addition, its DN50 nominal diameter and PN16 pressure class deliver superior performance in hot water, superheated water and compressed air lines.
A metal-to-metal sealing principle provides zero-leak performance even at high temperatures. Furthermore, the compact body and spring-assisted disc mechanism close instantly when flow stops, which raises safety. The brass (CW617N) body resists corrosion, and every unit is tested to EN 12266 for confirmed 100% sealing. Therefore, it works for years without maintenance. Threaded connections (ISO 228/G1) simplify assembly and allow horizontal or vertical mounting.
