The pressure reducing valve is a valve that adjusts the inlet pressure to a certain outlet pressure and depends on the energy of the medium to automatically maintain the outlet pressure stable. From the point of view of fluid mechanics, a pressure reducing valve is a throttling element whose local resistance can be changed, that is, by changing the throttling area, the flow velocity and the kinetic energy of the fluid are changed, causing different pressure losses, thereby achieving the purpose of decompression. Then rely on the adjustment of the control and adjustment system to balance the fluctuation of the pressure behind the valve with the spring force, so that the pressure behind the valve remains constant within a certain error range.
1. The direct-acting piston structure is adopted, the internal structure is very simple, no jamming, reliable performance and durable.
2. Resistant to dirt and water, no need for filters, no need
Bypass piping, piping is extremely simple, can save a lot of space and piping costs.
3. The outlet pressure can be adjusted precisely from 1 to 5.5 bar. In general, the outlet pressure can be considered regardless of the influence of the inlet pressure.
4. Excellent hydraulic characteristics, small pressure loss, decompression ratio can reach more than 10:1
