American standard folder lug double check valve Structural characteristics:

A, the folder lug double check valve structure, small size, light weight, great convenience for the valve installation, handling, storage and piping layout, and can save costs. 
 B, to reduce the line vibration, in order to reduce the line vibration to a minimum or to exclude line vibration, must be closed as soon as possible before the liquid flow counter-flow check valve. Each of the double-leaf check valves, which have half the size of the full-size check valve, experience reduced fluid resistance and faster movement to the closed position. Their radius of rotation is only half that of conventional check valves. Its halfway distance from the open position to its closed position halves the stroke time to 50% 
 C, double-check valve reduces water hammer, contrasts with full swing check valves, double-check valve The flap has been greatly reduced in weight, which can slamming and water hammer phenomenon to a minimum.

Clamp lug double-check valve structure, small size, light weight, for the valve installation, handling, storage and piping layout brings great convenience, and can save costs. American standard double-lobe check valve reduces the line vibration, in order to reduce the line vibration to a minimum or to exclude line vibration, it is necessary to close the check valve as soon as possible before the liquid flow has the opportunity to reverse flow.
