PN16~40 DIN Bellows Globe Valve

PN16~40
size:DN15 ~ DN400
Material: WCB 304 316 316L

Bellows welded to the stem parts and connecting pad provide a continuous metallic barrier between the process fluid and the atmosphere to achieve zero emissions
For added security there is also a stuffing box above the bellows for secondary sealing
The metal bellows are hydroformed multi walled structure which ensures them of 10000 full cycles at the maximum pressure for the valve
