Rebreather

Rebreather is a high-tech diving equipment. Its unique gas circulation system can filter the exhaled gas and supply it to the diver again, which greatly prolongs the diving time, and can also reduce the weight of the gas cylinder and improve the diving efficiency. The product also has relatively low noise and water resistance, making the diving experience more comfortable. The Rebreather is popular with diving enthusiasts as it is an important tool for deep sea diving and scientific expeditions. With the increasing demand for research and development of deep sea environment, Rebreather will become an important trend in the diving industry.

How Breather Valves operate? How Breather Valves operate?

However, when deciding on a set pressure, the weight-loaded Valve operation MAWP should be at least twice the required set pressure to obtain optimum flow. If the MAWP is less than 100% above the required set, the Valve could be larger in size than normally required. The possibility of Valve chatter and accelerated seat and diaphragm wear will exist if less than 20% over pressure is allowed. Simply stated, a Pressure/Vacuum Valve is not exactly like a high pressure safety Relief Valve and should not be sized at 10% or 20% over pressure. When sizing a Pressure/Vacuum Valve, consult the manufacturer flow curves and allow sufficient overset pressure.
