German AZ GASTECHNIK valves, AZ GASTECHNIK models, AZ GASTECHNIK prices

AZ GASTECHNIK valves are valves that reduce the inlet pressure to a required outlet pressure through regulation and rely on the energy of the medium itself to automatically keep the outlet pressure stable. From the perspective of fluid mechanics, a pressure reducing valve is a throttling element with variable local resistance, i.e., by changing the throttling area, the flow velocity and kinetic energy of the fluid are changed, causing different pressure losses, thereby achieving pressure reduction. Then, through the adjustment of the control and regulation system, the fluctuation of the pressure after the valve is balanced with the spring force, keeping the pressure after the valve within a certain error range.
