July 23, 2012 - GF Piping Systems introduced Type 523 Metering Ball Valve. The Type 523 features a V-notch ball with 180 degree turn rotation capability. This provides excellent flow control characteristics and better resolution than standard ball valves with only 90 degree rotation. The design also includes a circular scale that makes it extremely easy to read from all possible angles. The enhanced scale comes with a high contrast display that allows easier valve position reading.
The 523 Valve Series is available in a wide range of materials to meet the requirements of many different chemical applications. Materials include PVC, Polypropylene (PROGEF Standard) and PVDF Standard (CPVC and ABS are available on request) in 3/8" and ½" sizes. The valve can be easily actuated with GF Piping Systems EA21 Actuator and positioner to fully automate the user's flow control system. Other attributes of the micro-doser valve include integrated stainless steel mounting inserts, PTFE ball seals, and built-in threaded inserts for facilitating quick and easy installation. With valve ends the same for all 5-series valves and a wide range of available connections, users are assured of maximum flexibility.
Standards are available for ASTM, ISO, JIS, and BS.
