LHS745X low resistance backflow prevention device is mainly used for urban water supply pipe network pipe network with all kinds of users, or between the drinking water and in water, fire water, air conditioning, water, green water, water systems and other heterogeneous cross-connection between the effective partition, or vacuum equipment supporting installation, can strictly prevent backflow contamination. LHS745X low resistance backflow prevention device-in-one, in addition to ultra-low resistance, safe and more reliable performance, the body design expansion joint device and filter devices, reduce installation length dimensions, reducing the size of the installation, to bring customers a great convenience and benefits of a, LHS745X low resistance backflow prevention device Features: 1, low water loss, significant energy saving: the economic flow rate (velocity 2 m / s), the head loss is less than 3 meters; 2, the air partition, auto drain: The main valve is closed, the drain open automatically, intermediate chamber pressure relief to zero, the main valve between the upstream and downstream partition or zero air pressure cut off, cut off the safe and reliable performance. 3, land and materials, flexible installation: small size, light weight, the valve comes with filter and expansion joints, structural length of only 30% of existing similar products. 4, easy to maintain, automatic alarm: Detected no special pressure detector can be configured to automatically leakage alarm. Two, LHS745X low resistance backflow prevention device product specific parameters: Model: LHS745X-10Q LHS745X-16Q Nominal Diameter: DN65-DN400 Nominal pressure: 1.0Mpa 1.6Mpa opening pressure: ≤ 0.03Mpa local head loss: ≤ 0.03Mpa partition forms: partition partition or zero air pressure Body material: Ductile iron trim Material: 304 stainless steel Suitable temperature: ≤ 65 ℃ LHS745X low resistance backflow prevention device goole valve large number of companies have production, welcome customers to our consulting LHS745X low resistance backflow prevention The related matters, if the customer for LHS745X low resistance backflow prevention device products have special requirements, you can also contact the company directly for your order.
