Highest adjustment pressure 100 = 9.8MPa (100kgf/cm 2 ) 315 = 30.9MPa (315kgf/cm 2 ) Precautions in use ● Make the vent conduit as short as possible and the inside diameter of piping as small as possible. If the inside volume of the vent conduit is large, control may become unstable. ● Do not connect the tank piping to other tank piping but connect it directly to the tank. ●For the pressure increase value per turn of the adjust thread, refer to the section of the type number index “RD6 to 30”.
