Feature:1. Perfect Sealing: The return main has a double EPDM O ring to reduce noise to a very low level and double protection for safety performance.2. Individual Control: Each branch of the return water main is equipped with a temperature control valve that can be switched on and off via a handle for the branch in which it is located.3. Stainless Steel: The stem of the return main is made of stainless steel, which effectively reduces friction and prevents scaling.4. Easy Installation: Smooth inner wall with no roughness, main pipe diameter G1in, easy and quick installation with its own thickened bracket.5. High Accuracy: Our valves are highly accurate flow meters with scale display, stable quality and long service life.Specification:Item Type: Radiant Heat ManifoldMaterial: Stainless steelSurface Finish: Brushed finishNominal Pressure: PN≤1.2MpaHigh and Low Temperature Resistance: -20℃-110℃Forming Process: Using 1700/T forging and tempering processIntelligent Structure: Visible adjustable upper flow meter, lower intelligentProduct Thread: Thread standard in line with ISO228 standardWorking Medium: Water, non corrosive liquidsTest pressure: Mpa0.8-1.0Product Structure: Inlet water is spiral soft EPDM seal, return water is intelligent temperature control valve spoolBranch Pipe: 1216.Package List:2 x Radiant Heat Manifold4 x Valve2 x Pressure Watch10 x Fixing Accessory8 x Screw1 x Instruction
