Flange Type Static Balancing Valve

Product Description

Performance and characteristics:
Nominal diameter:DN50...DN500;
Good flow character,the relative flow and a linear relationship between the relative opening;
The precise valve opening direction, can be accurate to fully open the valve 1% degrees;
Lock opening - reliable memory function;
The best cut-off function;
The EPDM seal, reliable sealing performance;
The valve body, valve stem, valve core can provide GJL250, ductile iron GGG450-10 according tothe different requirements of users, choice of stainless steel or brass material;
The threaded and the flanged connection is in compliance with EN10226 and EN1092-1/2;
We go with PED and valve manufacture license of special equipment.
Purpose:
1, Building air conditioning or heating pipe networkBuilding air conditioning and heating pipe network system, in order to meet the requirements ofenergy conservation, it is required to ensure that all the competent and branch are in line with thedesign flow. This should be in the main, dry pipe, balancing valves are installed on riser and branch.
2, District heating pipe network
3, Heat exchanger group cargo water chillerIf the flow rate of each unit is not consistent with the rated flow, the heat exchange unit or the coldwater unit is not in line with the rated flow, so that the unit can't run efficiently. In this case, should beinstalled in each heat exchanger unit or chiller at the balance valve, so that each unit can reach thedesign flow, to ensure the safety of each unit, normal operation.
4, Thermal power stationIn the thermal power station or boiler room to a number of hot water or steam stations for the system,in order to make the heat station to obtain the required flow, should be in the thermal station of a loopside of the installation of the balance valve. In order to ensure that the two loop flow for the design flow,the thermal station of the two loop should also be installed on the balance valve.
