Minimess® 1615 Series Gas Charging Valves

Hydrotechnik offer a range of high quality gas charging valves and test points for use with most gases, standardising on the Minimess® 1615 series design.

Minimess® 1615 gas charging valves are manufactured with very precise internal tolerances to give maximum sealing integrity, not possible with standard Minimess® test points. Manufactured in 1.4571 (316Ti) or 1.4104 stainless steel grades and special compound Viton or Buna Nitrile sealing gives high performance, even in the harshest of environments.

Production screw-in threads include ISO228-G1/4" BSP, 1/2"-20 UNF and M14x1.5, with other threads available on request.

Optional Product Testing Includes:

• 100% pressure testing
• 100% helium odour test
• 100% cryogenic testing at -40°C
• 3.1B certificates included
