300X slow shut-off check valve

300X slow shut-off check valve

300X slow shut-off check valve is used at outlet pipe of pump, with its open and close speed adjustable , and also used at high building for reducing water hammer and water slamming.

300X slow shut-off check valve is an intelligent valve intended for installation in the pump outlet of a high-rise buildings water supply system. When uses it effectively prevents the reverse flow of a medium, as well as water hammer-type phenomena. This valve utilizes a motorized valve, check valve and water hammer eliminator at the same time and can effectively increase the safety and reliability of a water supply system .It integrates such functions as slow opening, fast and slow closing in order to eliminate water hammer, so as to prevent the occurrence of pump-on water hammer and pump-off water hammer. The valve can automatically realize turning on/off according to the operation specification of the pump. By pressing the On/Off button of the pump motor; a large flow and small pressure loss can be achieved. The slow shut-off check valve is suitable for use with pipes of 600 caliber and below. Pressure Rating: PN10. PN16. PN25/Class150Size Range: DN20mm-DN800mm (3/4" - 32") Test and inspection: GB/T 13927 API598.
