The 161369112 is a wafer check valve in the 369 PVC-U series with a Hastelloy C spring, designed for use in piping systems with up to PN16 pressure rating. It has a nominal diameter of DN250, weighs 3.500 kg, and supports vertical and horizontal mounting. The valve requires a stabilizing zone of at least five times the nominal diameter before and after installation, and is intended for use with flange adaptors adhering to ISO/DIN or ANSI/BS standards. Sealing is achieved with a special flange gasket. The valve has a minimum opening pressure of 20 mbar horizontally and 30 mbar vertically, and requires a minimum water column height of 2 meters for sealing. It is suitable for installation only where direct connection to pump flanges or bends is avoided.
