Tilting Disc Check Valves

SIERRA model 5400 is a swing type tilting disc check valve that is a development of the traditional type swing check valve that has been designed to allow for frequent flow reversals without causing wear in the shaft seat which is a common feature of the swing check. The compact body of the tilting disc saves space during installation hence reducing construction cost. The disc is pivoted in the upper one third of the valve body; hence the disc eccentricity is much smaller than that of the conventional swing check. Due to the shorter distance travelled by the disc the tilting check valve closes more rapidly hence resulting in less slam and water hammer Tilting disc check valves can be supplied with counter weights or springs to assist closure hence reducing shut off time. They can also be equipped with a double stage hydraulic damper (oil dashpot) for slow closure requirements.
