AYVAZ ÇV-25 Double Plate Check Valve DN400 PN16
Instant backflow protection with silent, low-loss performance for large-diameter lines.
The AYVAZ ÇV-25 Double Plate Check Valve delivers an advanced solution for preventing backflow in industrial lines. In addition, its DN400 nominal diameter and PN16 pressure class suit large-scale applications. Moreover, the double spring mechanism closes the plates instantly when flow direction changes, therefore protecting line integrity.
A rubber-sealed disc structure minimizes pressure loss, and the GG25 cast iron body with GGG 40 ductile iron disc offers superior wear resistance. Furthermore, the double spring design ensures silent operation and minimizes vibration. Consequently, it is fully compatible with DIN, ANSI, JIS and BS flange standards for fast and safe installation. In particular, horizontal and vertical mounting options maximize efficiency from the installation space.
