German Rieger valves Rieger models Rieger prices

Rieger valves are valves that reduce inlet pressure to a required outlet pressure through regulation and rely on the energy of the medium itself to automatically maintain stable outlet pressure. From a fluid mechanics perspective, a pressure reducing valve is a throttling element with variable local resistance; it changes the throttling area to alter flow velocity and fluid kinetic energy, creating different pressure losses to achieve pressure reduction. Then, through the adjustment of the control and regulation system, the fluctuation of downstream pressure is balanced with the spring force, keeping the downstream pressure constant within a certain error range.
