Minimess® Gas Charging Valves

Hydrotechnik offers a range of high-quality gas charging valves and test points suitable for use with most gases in the Minimess® 1615 series design.

Our Minimess® gas charging valves are manufactured with precise internal tolerances to give maximum sealing integrity, which is impossible with standard Minimess® test points.

Manufactured in 1.4571 (316Ti) or 1.4104 stainless steel grades with special compound Viton or Buna Nitrile sealing gives high performance, even in the harshest of environments.
