  • Document GB-A-2111154 describes a gas passage control valve with a screwed pressure gauge of this type.
  • said pressure gauge is first screwed with sufficient torque to ensure the tightness, then with an additional torque intended to deform the aforementioned washer, so as to reach the angular position required for reading, that is to say the indexing of said pressure gauge.
