What is the maximum supply pressure for the Compressed air shut-off valve V3V, NEW DEAL series?

The maximum supply pressure for the Compressed air shut-off valve V3V, NEW DEAL series is up to 18 bar.

How does the triple locking mechanism on the Compressed air shut-off valve V3V, NEW DEAL series enhance safety during maintenance?

The triple locking mechanism on the Compressed air shut-off valve V3V, NEW DEAL series significantly enhances maintenance safety by providing three independent positive locks that prevent accidental re-opening of the valve while work is carried out. This redundancy ensures the working system stays reliably isolated from supply air even if one locking element fails or is improperly engaged. Combined with the pushâbutton opening design and mushroom actuator (ensuring clear tactile control and high flow capability), the triple lock minimizes the risk of unintended pressurisation, protecting personnel and equipment during maintenance.

Can the Compressed air shut-off valve V3V, NEW DEAL series be operated while system pressure is present?

No. the Compressed air shut-off valve V3V, NEW DEAL series is designed as a manual shut-off that separates the working system from the supply air and features a triple locking mechanism; it must be operated (opened) by pressing the button and is intended to isolate the downstream system. Because it provides positive isolation and is rated for supply pressures up to 18 bar, it should not be operated (i.e., disassembled or manipulated beyond normal button actuation) while system pressure is present except for normal opening/closing by the button. Follow safe work practice: depressurize the downstream system before maintenance or removal. The valveâs mushroom opening mechanism supports high flow (1500â2900 l/min depending on port size at 6 bar inlet and Îp=1 bar), but this does not imply safe operation under pressurized maintenance conditions.
