        • 产品型号: FisherA81
        • 产品类别: FisherA81旋转型调节阀

         

        Quarter-turn performance— The valve has a square shaft-to-actuator connection and offers automated on-off, quarter-turn performance.

        Global Standards— The valve meets API, ASME, and EN standards, making it suitable for use in all world areas. An optional mounting bracket provides ISO 5211 actuator mounting capability.

        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.

        Improved shaft-disk pinning— The improved expansion pin system ensures there is a positive, durable connection between disk and shaft. This 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.

        Excellent Emissions Capabilities— The optional ENVIRO-SEAL® packing systems, are designed with very smooth shaft surfaces and live-loading to provide improved sealing, guiding, and loading force transmission. The seal of the ENVIRO-SEAL system can control emissions to below 100 ppm (parts per million).
