Product introduction
The imported automatic exhaust valve produced by Breel can be driven by automatic mode, threaded or flanged by connection method, float type or spiral type by sealed structure, PTFE by sealed structure, PN1.0-2.5MPa pressure range , The nominal diameter is 10mm-300mmmm, the material can choose brass, stainless steel, cast iron. Because the valve is used in a very wide range, the same valve has different combinations in different situations and working conditions.
Product Details
Operation principle of imported automatic exhaust valve: When the pipe starts to fill with water, the plug stays in the open position for a large amount of exhaust. When the air is exhausted, water accumulates in the valve, the floating ball is floated, and the plug is driven to the closed position. Stop a large amount of exhaust.When the water in the pipe is normally transported, if a small amount of air collects in the valve to a considerable extent, the water level in the valve drops, and the float drops with it.At this time, the air is discharged through the small hole. When the pump stops, the water flow in the pipe When empty or when negative pressure is generated in the tube, the plug is quickly opened at this time to suck air to ensure the pipeline is complete.

Spiral exhaust valve, micro bubble exhaust valve, slag exhaust valve, degassing decontamination device
1. Energy saving;
2. Save maintenance work;
3. Maximum protection of air conditioning water system;
4. Improve the efficiency of the system;
5. Reduce failures;
6. Significantly reduce test run time;
7. Optimize heat transfer efficiency;
8. Extend the service life of parts;
9, no oxidation corrosion and cavitation;
10. Quiet operation;
11. No bypass or shut-off valve is needed to maintain the minimum pressure loss (about 0.5 ~ 5Kpa), the pressure remains constant and will not block the fluid.
12.Three-year guarantee
Unique design of spiral exhaust valve, micro-bubble exhaust valve, slag exhaust valve, degassing and decontamination device;
1. The unique valve structure ensures that it will not leak and be blocked. Standard thread can be connected to exhaust pipe or check valve
2. Lifting rings make installation easier;
3. The specially designed and large-capacity air chamber ensures that it will not be blocked by dirt even when the pressure fluctuates greatly;
4, used to discharge a large amount of gas when adding water, also used to discharge floating objects;
5. There are many different pipe diameters to choose from, and the standard product is up to 300mm. Optional welding or flange connection;
6. The slag comes out of the water channel without affecting the pressure drop or flow;
7, thick shell guarantees durability;
8. The patented special pipe is the core of the Spirax exhaust gas slag remover, which is designed to separate large, small and tiny bubbles and slag, and has only a small water resistance;
9. Large capacity slag bin reduces the frequency of manual sewage;
10.Manual blowdown valve
