Automatic Pump-trap Stations UNA PK Station and UNA PK HK Station
The GESTRA UNA PK Station/UNA PK HK Station automatic pump-trap stations are plug in systems specifically designed to remove condensate from plant under ‘stall’ conditions. The whole system is capable of handling capacities up to 2 800 kg/h pumping and 9 000 kg/h trapping, depending on available differential pressure.

Purgeurs à flotteur UNA 45 MAX, UNA 46 MAX, UNA 46A MAX PN 40 / Class 300 DN 40, 50, 65
Les appareils des types UNA 45 MAX, UNA 46 MAX et UNA 46A MAX servent à évacuer le condensat provenant de la vapeur d’eau des appareils consommateurs chauffés par la vapeur. En fonction du niveau, un flotteur commande l’ouverture de l’organe de fermeture. Ceci permet de réguler l’écoulement. Lorsque l’ouverture est maximale, l’écoulement dépend du diamètre de l’organe de fermeture (OF) monté. Lorsque le flotteur est soulevé au fur et à mesure que le niveau augmente, l’aiguille de buse sort d’abord de la soupape pilote. Une faible quantité de fluide traverse alors la soupape pilote. Le fluide comprime le soufflet de l'unité de réglage. Ceci entraîne l’ouverture complète de l’organe de fermeture.

Non-Return Valve for Sandwiching between Flanges PN 10/16/25/40, ASME Class 125/150/300 RK 86, RK 86A, DN 15-200, NPS 1/2-8 RKE 86, RKE 86A, DN 15-100, NPS 1/2-4
RK and RKE non-return valves are used to prevent the return flow of fluid in pipes. Only RKE non-return valves may be used as end valves (e.g. vacuum breakers). This equipment has passed the appropriate tests and bears the relevant markings, and must not be used with safety-relevant functions (e.g. safety valves). RKE non-return valves are only available with a metal valve disk.
