Air conditioning valve - pole special ball valve air-conditioning ducts and valves factory wholesale price direct three specifications: Nominal pressure: 2.0 MPa Working medium: water, non-corrosive liquid, saturated steam Working temperature: -20 ° C ≤ t ≤ 110 ° C pipe thread to ISO 228 standard valve body brass CW617N European standards of production, greatly improve product tensile, compressive and impact strength. Ball Valve Installation Instructions: 1. Ball is the piping system can be quickly ended, connected to control unit media, to ensure personal and property safety, we must correctly select the appropriate valve shall regulate the installation, use and maintenance. 2, the application installation wrench tighten the screw on the same side of the hexagonal or octagonal parts, hexagonal or octagonal wrench should be part of the other side of the valve to avoid valve distortion, you must use Teflon tape or thread sealing glue sealed. 3, the installation tighten the valve to choose the appropriate torque wrench or pliers, screw effective thread length can be, do not lead to excessive top end face pressure sphere surface damage caused by leaks, to ensure the normal use of the valve in the pipeline as imports installed at the filters. 4, ball valve handle is based on use of the environment and the environment and corresponding torque two design alternatives do not switch to increase the arm, in order to avoid excessive operating torque and damage to the valve closed while excessive speed will produce water hammer effect instantaneous pressure doubled. Pipeline pressure or frequent temperature fluctuations will reduce its life, preventive measures should be designed accordingly. 5, stem seal PTFE packing, such as corrosion leak may tighten when packing gland to compensate shall replace the packing shed media pressure.
