300X Flow Control Check Valve, 300X Flow Control Check Valve Manufacturer,300X Flow Control Check Valve Manufacturer, 300X Flow Control Check Valve Supplier,Products,Export,Facotry.

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