Features
-
The actuator/valve assembly can easily switch between push-down-to-open and push-down-to-close operation—no additional parts required, making it highly adaptable.
-
Both metal and soft seal rings feature pressure-assisted sealing, guaranteeing leak-tight shutoff under any pressure differential.
-
Standard conductive packing ensures proper electrical bonding, a critical safety feature for hazardous area applications.
-
With the right trim components, the valve reliably operates even in high-temperature environments, expanding its suitability for demanding conditions.
-
For precise travel indication, the shaft’s reference line aligns with the disk position markings on the packing follower, providing clear visual feedback.
-
Redundant shaft retention—via the packing follower, anti-blowout ring, and shaft groove—secures the shaft firmly within the valve body, adding an extra layer of operational safety.
