Description

Water hammer phenomenon occurs in closed pipes when the fluid is accelerated or decelerated very quickly, due to the rapid closure of valves or taps or as a consequence of a circulation pump stopping. The effect consists in the propagation of over- and underpressures along the pipes, which may result in noise and damage to the whole system. The water hammer arrester, when installed close to single-lever mixing taps, solenoid valves, ball valves, etc., prevents such negative effects. The use of water hammer arrester is recommended in particular by UNI 9182 regulation “Cold and hot water supply and distribution systems. Design, testing and management criteria”. 15mm brass body chrome plated Max working pressure 10 bar Max working temp 90°C
