Differential pressure control valve

product manual
800X differential pressure bypass balancing valve is used to balance the pressure difference between the air conditioning system and the return water, which can improve the utilization of the system, maintain the accurate and constant value of the differential pressure, and minimize the noise of the system. Damage caused by large pressure difference to the equipment. The 800X differential pressure bypass balancing valve is superior to other balancing valves. It does not require other mechanical functions. It relies on the pressure difference of the medium itself to achieve the function of system balancing, saving energy and installation space.
Structural features
1. The pressure difference between the two ends of the differential pressure bypass valve and the controlled system supports the variable flow operation of the user system.
2, relying on the pressure difference to work automatically without external power.
3. The control pressure difference can be directly displayed.
4, you can directly set the control pressure difference.
5, control differential pressure adjustment is sensitive, easy to operate.
6, medium temperature: 0 ~ 150 ° C.
7, control pressure difference adjustable range: 0.05~0.6Mpa
8, control differential pressure error ≤ ± 5%.
