CE Certification Energy-Saving Silencer Check Valve Suppliers, Supplier

Energy-saving silencer check valve has two connection modes: flange connection and clamp connection. The valve disc adopts the central guide shaft at both ends of the inlet, which is flexible to open and close and accurately positioned. It can be installed horizontally or vertically. The valve disc is spring-loaded, and its rapid closing can effectively reduce water hammer pressure. The sealing surface adopts a combined sealing structure of O-ring elastic seal and metal hard seal, which has good sealing performance and no noise when closed. It also has small size, light weight, and small fluid resistance. It can be installed at the outlet of the water pump in fire protection and HVAC systems to prevent backflow and damage to the water pump.
