Silent Check Valve

Silent check valve disc is round, disc rotates around the axis of the seat, due to the channel into a streamline in the valve, flow resistance is smaller than lift butterfly check valve, suitable for low flow velocity and large diameter, which flow does not change a lot.

We strictly performance the hydraulic test for each valve according to the worldwide standards and customer requirements.

Features:

(1)The most reas onable and streamlined design;

(2)The MIN. Noise while direct flow or back flow;

(3)Head loss only 0.18bar with velocity of 2m/s;

(4)Shut off speed is only 0.2s;

(5)Integral body and flow guide design , full rubbercoated disc;

(6)FBE coating inside and outside Min 250 u .
