Haiqiao Yap Valve Manufacturing Co. [VB7000 electric pressure bypass valve / control valve / Valves] manufacturer, has substantial cash to ex-factory sales! Adhere to the "quality first, integrity management" purposes, to provide customers with affordable products and perfect service, welcome to buy! VB7000 electric pressure bypass valve _ _ electric electric pressure control valve pressure balance valve VB7000 electric pressure bypass valve role VB7000 electric pressure bypass valve / control valve / balancing valve is suitable for central air conditioning chilled water / hot pressure bypass water system control applications. Pressure bypass the main role is to maintain the chilled water / hot water system can be at a lower end of the load, to ensure the normal operation of the chiller / heat exchangers and other equipment. VB7000 electric pressure bypass valve works differential pressure controller DPC-1 is detected by the pressure supply / return main difference compared with the set value by controlling the opening of the electric two-way valve, so that between the water supply and return water achieve bypass, in order to maintain the desired pressure difference. When the pressure difference increases, red and yellow contacts connected contacts, pressure reduction, red and blue contacts connected contacts, red contacts can stay in the middle position, with no electrical connections to other contacts. Differential pressure bypass valve VB7000 VB7000 electric electric pressure bypass valve pressure bypass valve use VB7000 electric central air conditioning is suitable for chilled water / hot water system, bypass control purposes. The main role of electric pressure bypass that maintain chilled water / hot water system can lower end of the load, to ensure the normal operation of the chiller / heat exchangers and other equipment. Electric pressure bypass valve installation instructions Figure A, a differential pressure controller detects that the supply / return manifold pressure difference, so the control is accurate. Panel b, the pressure difference is detected for the controller / bypass valve pressure difference across the return manifold, detected only supply / return water partial pressure difference, the control is not accurate.
