structural characteristics

● Various actuators can be equipped according to requirements to set adjustment functions.

● The bellows assembly has a minimum of 15 '000 full-stroke open/close cycles at the maximum pressure level. Generally, HAC276 material is used, which has excellent corrosion resistance.

● Fully automatic surfacing welding allows the valve stem, bonnet, and valve body to form a barrier between fluid and the atmosphere to ensure zero leakage.

The sealing surface is made of cemented carbide surfacing and has excellent partition properties.

Seat sealing class

Class 1: Class IV ASTM/ANSI B16.104
