GEMÜ has introduced the new GEMÜ 537 manually operated globe valve to its product range. The new valve type uses the same valve bodies as the GEMÜ 534 and 532 actuated designs.

Valve bodies in nominal sizes DN 15-50 in cast stainless steel 1.4408 and SG iron GGG 40.3 (EN-GJS-400-18-LT) are available. The maximum operating pressure for nominal sizes DN 15 - 40 is 25bar, for DN 50 16bar.

The standard version of these valves can be used up to 18C and the PTFE gland packing is suitable for steam. Versions for higher temperatures and with other seals are available on request. Connections available are flanges to EN 1092/PN 16 and PN 25 form B, length EN 558, series 1.

The new manual valves can also later be retrofitted with the pneumatic actuators of types 534 and 532, if required. An ATEX version of these valves is also available on request.
