What are the main types of ATOS pressure reducing valves? Description

ATOS Atos is a leading manufacturer of electro-hydraulic components and systems: integrated hydraulic and electronic advanced technology to enhance the performance of modern machinery Atos ATOS headquarters - 21018 Sesto Calende, Italy near the Alps, at Lake Maggiore The town on the shore is 15 km from Milan Malpensa Airport. Total turnover: 60 million EUR, total staff 400, annual production of components: more than 1 million pieces. What are the main types of ATOS pressure reducing valves?
1, ATOS pressure reducing regulator
Main features: 1. Piston type above DN65. For the diaphragm to improve the life of more than 3 times; 2, DN50 or less, with a nylon reinforced rubber flat diaphragm instead of the original diaphragm, also increased the life of more than 3 times. Applicable medium: water, air. Medium temperature: 0~90 °C.
2, bellows ATOS pressure reducing valve
This valve is used on steam, air and other non-corrosive gas pipelines with a temperature below 180C. It is adjusted to reduce the pressure of the medium passing through the valve to a required outlet pressure and keep the outlet pressure of the medium relatively stable. However, the difference between the inlet pressure and the outlet pressure must be greater than or equal to 0.5 bar.
3, branch pipe ATOS pressure reducing valve
I. Use The ATOS pressure reducing valve for water produced by our factory is mainly used in various building water supply systems, fire protection systems, central air conditioning systems, heating systems, etc. It is used for branch pipe decompression, which can make the water supply pressure distribution more balanced, avoid partial water supply overpressure, and optimize the water supply partition of high-rise buildings. It can replace the zone-controlled variable frequency water pump, and can replace the zoned water pump in the fire water supply system for the household water supply system, which can protect all the faucets and other water appliances.
Second, the characteristics of the direct-acting diaphragm structure, the internal structure is very simple, no jamming, reliable performance, durable. It is resistant to dirt and scale, does not require a filter, does not require a bypass pipe, and the piping is extremely simple, saving a lot of space and piping costs. The outlet pressure is precisely adjustable. Under normal circumstances, the outlet pressure can be considered to be unaffected by the inlet pressure (the change in outlet pressure is 8% of ΔP1). Excellent hydraulic characteristics, low pressure loss, and a pressure reduction ratio of 10:1 or more. It can meet a variety of decompression requirements, especially for branch pipe decompression systems.
Third, the working principle The outlet pressure acts on the bottom surface of the diaphragm and the bottom surface of the valve flap. When it exceeds the set value of the spring, the spring is compressed to close the valve flap. As long as there is no downstream flow, the outlet pressure will remain at the set value (the amount of change is only 8% of the inlet pressure change); when the downstream water is used, the outlet pressure drops, the spring pushes open the diaphragm, and the ATOS pressure reducing valve is opened. After the water flow is continuously circulated for a while, the opening of the ATOS pressure reducing valve produces a self-damping effect, which makes the opening and closing action tend to be stable. Fourth, the possible causes of failure 1. Frost damage, should pay attention to heat preservation in cold areas. 2. The direction of water flow is wrong, the ATOS pressure reducing valve becomes a check valve, and the outlet pressure is 0. 3. The spring is tightened too tightly to close, and the ATOS pressure reducing valve will pass through P2=P1. 4. The bypass pipe leaks. Deviating from the set value of P2, in view of the superior reliability and durability of the ATOS pressure reducing valve, it is recommended not to install a brightness tube.
4, steam ATOS pressure reducing valve
The steam ATOS pressure reducing valve is suitable for use on steam lines. Through the adjustment of the ATOS pressure reducing valve, the inlet pressure can be reduced to a certain required outlet pressure. When the inlet pressure or flow rate changes, the ATOS pressure reducing valve can automatically keep the outlet pressure fluctuating within a small range by relying on the energy of the medium itself.
