Approximately linear flow characteristic— An approximately linear flow characteristic provides precise throttling control.
Global Standards— The valve meets API, ASME, and EN standards, making it suitable for use in all world areas.
PEEK/PTFE bearing as standard— The PTFE-lined PEEK bearing is a patented low friction, low wear bearing. It allows the valve to operate under high pressure drops for a high cycle life while maintaining low torque. The "drop-in" bearing design enables fast, easy maintenance.
Spline-ended Shaft— The splined shaft with clamped lever and single-pivot linkage reduces lost motion between the actuator and the valve shaft.
Improved shaft-disk pinning— The improved expansion pin system ensures there is a positive, durable connection between disk and shaft. This connection reduces backlash and wear in the drive system, optimizing long-term performance. It also makes disassembly for maintenance quick and simple with no need for special tools.
New Spring-Loaded Shaft— The spring in the outboard shaft provides support to the drive train and disk, enabling the shaft to be installed in both horizontal and vertical orientations with no detriment to performance or cycle life. This complements the ability to mount the actuator on the left- or right-hand side, enabling access for any installation. |
