FLOWSPEC intelligent water meter control valve depends on the water self pressure in the pipeline to achieve in the valve open and close. Electric phase converter overcomes the problem of easy blocking of pilot hole, providing direct, quick and accurate control. FLOWSPEC intelligent water meter control valve body is designed according to fluid dynamics theory, with advantages of big flow and low resistance. Double chamber actuating device features with slow operation and tight closing. FLOWSPEC intelligent water meter control valve slow operation can prevent of water hammer and vibration effectively. Resilient and flexible disc make sure on the valve perfect sealing performance. The disc is separated from the bottom guidance support, easy for exchange.
