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.
