Product performance and uses: RVG series relief valve guide design, low noise, the pressure in the system can be stable, remote control and unloading. , Product technical parameters: 1, adjust the pressure, relax the lock nut and slowly turn the handle clockwise elevated pressure, counterclockwise pressure drop callosum, the adjustment is completed, do not forget to tighten the nut, the pressure by installing stalls circle limit, when a working pressure can not be reached, you can remove some of the stalls circle. 2, a direct-acting return pipe may not be connected to the return pipe and other valve should be directed back to the tank, and back to the tank internal volume is too large frequency vibration is likely to occur. Therefore, shall be able to reduce the length and the diameter of the pipe.
