Abstract
PURPOSE: To enable to regulate arbitrarily for the maximum valve opening of the pressure control valve, by providing the bleed set bleeding the operating fluid fed to the drive section of the pressure control valve via the pilot vlave externally.
CONSTITUTION: Between the pressure control valve 4 and the pilot valve 5, the movable bleed valve 9 is provided so that the amount of bleed of the bleed valve can be made variable through the operation section 10. For example, to a district many in general livings in city gass supply, a signal is fed to the operation section 10 at night to greatly set the amount of bleed of the bleed valve. Thus, a part of gas fed from the valve 5 to the drive section 8 is bleed to down stream much than usual via the branch pipe 6. Accordingly, the gas supply amount to the drive section 8 of the valve 4 is decreased as the bleed amount increases to limit the maximum opening of the valve 4. Thus, to the district less in gas consumption, inconvenience supplying excessive amount of gas can be avoided. on the other hand, to the districts much in gas consumption even at night, the bleed amount of the valve 9 is set at small position.
