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)
-------------------------------
Versatile safety relief valve available in bronze, carbon steel or all stainless steel construction, suitable for a wide range of steam, air, gas and liquid applications. High capacity full nozzle design is available with metal to metal, PCTFE or elastomer O-ring seating. Short tuned blowdown and backpressure tight body minimizes fugitive emissions and product losses in the event of valve operation.
