GR Series Regulator;
GR Series Regulator is a valve that reduces the inlet pressure to a required outlet pressure by adjusting it and relies on the energy of the medium itself to keep the outlet pressure stable automatically. From the point of view of fluid mechanics, pressure reducing valve is a local resistance that can change the throttling element, that is, by changing the throttling area, the flow rate and fluid kinetic energy change, resulting in different pressure loss, to achieve the purpose of decompression. Then, the fluctuation of the pressure after the valve is balanced with the spring force by the control and adjustment system so that the pressure after the valve is kept constant within a certain error range.
