 The structure characteristics of Empty row check H48H H48Y

1, the valve is consist of the check valve, Recycling bypass control valve and throttle device.

2, work with recirculation bypass valve, this valve can prevent the high pressure water hammer damage to the water supply system, to maintain the safe operation of the system.

3, the main valve disc with pipe flow or pressure change and mobile, with the help of medium pressure and spring force close the main valve mouth, then drive the bypass valve open, keep pump minimum allowed flow automatically. When the main valve fully open, the bypass valve is closed.

4 streamline structure design, the use of special valve core, with functions of accurate control flow, under the condition of high pressure difference have cavitation abrasion resistant and not easily get the characteristics of the noise and vibration.

5, the valve sealing surface using cobalt-based hard alloy surfacing and become, wear-resisting, scouring resistance, cavitation resistance, reliable sealing, long service life.

6, maintenance and maintenance convenient and quick

7, the valve is suitable for vertical installation.
