1-5.3 Seat Protection
Electro-hydraulic actuation, such as the Hawk, can create extremely high seating thrust or torque. In some
cases, applying excessive actuator force while in the seated position can permanently deform the seating
surface, which may lead to process fluid leak by. The Hawk’s Safe Seat feature protects the valve in two
ways, by hydraulically limiting the maximum force the actuator applies to the valve in the seated position
and by maintaining a constant force on the seated valve. Since the Safe Seat is a hydraulic system it is
precise, adjustable, and rugged.
