500 Series

ITA500 series

Valvola di sicurezza ASME. Disponibile in bronzo, acciaio al carbonio o acciaio inox. Adatta per una vasta gamma di applicazioni come vapore, aria, gas e liquidi. Elevata capacità di progettazione degli ugelli, disponibile a passaggio totale con sede metallica, PCTFE o O-ring. La regolazione degli spurghi e la tenuta del corpo alla contropressione riducono al minimo le fuoriuscite e le perdite di prodotto quando la valvola sta funzionando.

ASME Section VIII Aria, vapore e liquido da 1/2 a 2 NPT. Gamma standard di pressione da 5 a 1200 psig ad un massimo di 426°C (800°F)
