Product Description

DYP4X roll-type composite exhaust valve application range:
This series of exhaust valve is suitable for clean water, raw water, drinking water system, suitable for temperature -20ºC~90ºC
 
DYP4X rolling shutter compound exhaust valve features:
1 Fast, large amount of exhaust. The exhaust port adopts a permeable structure, when the pipeline begins to water, it can quickly discharge the gas in the pipe, and the design of the valve channel structure uses the principle of aerodynamics to ensure that the float will not be blown up when the high-speed exhaust, so as to achieve the exhaust under the full pressure condition.
2 Trace exhaust. When the tube is filled with water, the main exhaust port is sealed, and a small amount of gas generated during operation will be discharged through the roller shutter micro-exhaust valve to avoid the accumulation of gas in the tube; The roller shutter micro-exhaust valve adopts the roller shutter sealing structure, sensitive action can quickly discharge the accumulated small amount of gas and can be quickly sealed, greatly reducing the possibility of being blocked by debris, the same exhaust port can adapt to a large exhaust pressure range, and has the function of self-purification.
3 Quick suction. When the flow of water in the pipe is interrupted or negative pressure is created, the main float ball will fall, open the main exhaust port, and quickly inhale the gas and replenish it into the pipe to protect the pipe from damage. At the same time, through the best design of the flow channel structure in the valve, the intake volume and intake speed can be controlled.
4 Valve body, valve cover and other parts using special anticorrosive paint, float ball using stainless steel, trace exhaust valve using non-metal anti-corrosion materials, so that the small size of the best performance greatly improved, the entire exhaust valve both in line with the drinking water system standards and suitable for other water systems.
5 Antifreeze, anti-theft structure. Valve design with antifreeze, anti-theft structure, roll-type micro-exhaust valve built-in installation, effectively protect the safety of micro-exhaust valve, micro-exhaust structure is not from the top of the valve to exhaust (such as the country is used in the south, you can dismantle the internal exhaust pipe, so that the micro-exhaust valve top began to exhaust), to ensure that the top of the valve always has a section of air, Effectively protect the valve body from freezing and cracking.
