Medium Pressure Gas Combination Valve【Japan only release】

Model No.


【NEW】A hydrogen gas compatible option is added to the working fluid to guarantee use with hydrogen gas. In order to identify the hydrogen gas line, the dedicated color (red) is used on the bonnet, etc., and the hydrogen nameplate is attached.
The medium pressure (0.3MPa) governor is integrated with the secondary side shut-off valve to significantly reduce pressure loss. Compared with the conventional product (TAC-25), the flow rate at the same differential pressure is increased by 300%! Stable pressure control is realized even at high flow rates.
