A coupling manifold valve is a control component used for flow isolation and regulation in underfloor heating and water distribution systems. The body is typically manufactured from forged CW617N brass with tensile strength between 350 and 500 megapascals. Allowable working pressure ranges from 10 to 16 bar, and test pressure reaches up to 24 bar. Operating fluid temperature varies from 5 to 95 degrees Celsius with peak tolerance up to 110 degrees Celsius. The coupling connection usually supports 16 to 20 millimeter pipes with 3 4 inch eurocone thread. Permissible leakage rate is defined below 0.1 milliliter per minute at nominal pressure.
The structure includes a brass machined stem, EPDM O rings, and a brass compression nut. Handle rotation angle is typically 90 degrees with operating torque below 5 newton meters. Pressure drop in fully open position remains below 0.3 bar at 2 cubic meters per hour flow rate. Stem sealing uses dual O rings for enhanced safety. Nickel surface plating with thickness from 10 to 20 microns improves corrosion resistance. Quality control includes hydrostatic testing, 5000 cycle endurance testing, and precise dimensional inspection.You can order and buy Ball valve from Iran by contacting us through whatsaap and email.

Guide to Selecting the Proper Size of Compression Manifold Valve in iran
Selecting the correct compression manifold valve size must be based on pipe diameter, design flow rate, and allowable pressure drop. First measure the outer diameter of the PEX or multilayer pipe common sizes are 16×2, 20×2, and 25×2 mm. The manifold inlet thread is typically 1/2 or 3/4 inch and must match the outlet connection precisely. Each heating circuit usually requires 1 to 3 liters per minute flow, and the internal valve diameter should limit pressure drop to below 0.1 bar. Standard brass compression valves operate at 10 to 16 bar and temperatures up to 95 degrees Celsius. High temperature resistant O rings improve sealing durability. In larger systems, sizing should ensure flow velocity remains below 1.5 m/s to control noise and pressure loss.
