Flange static balance valve is a main hydraulic balancing product used to ensure high precision flow pre-regulation of hvac water system, to ensure that the whole water system is in static hydraulic balance.

BCD series balancing valve through a dedicated flow test instrument, at the beginning of the air conditioning water system commissioning, the scene to forecast water system flow adjustment, ensure all equipment and piping at the end of the flow after adjusting the qualified and meet the design flow.

BCD flange static balance valve series, widely used in hvac water system of supervisor, branch pipe, and terminal equipment in the water, and at the same time can also be applied to other same or similar functional requirements.

The structure is briefly

1. Simplified pipeline design and resistance calculation;
2. Quick and convenient installation;
3. Measuring and pre-adjusting flow in the field through the convenience of special instruments;
4. Convenient to measure differential pressure on site;
5. With clear opening instructions and digital display, it can be conveniently opened
To regulate and limit;
6. Achieve the pressure difference measurement through the built-in test pressure joint;
7. Non-lifting handwheel is easy to operate;
8. Protective cap of travel limit nut;
9. Stem is 416 stainless steel, body cast iron surface spray corrosion resistant epoxy resin.
