GF Piping Systems has introduced the new Metering Ball Valve Type 523, completing the company’s 5 Series Generation of Ball Valves. The new series incorporates a number of unique features that include improved flow control, easy actuation, new scale and display, and large material range for application versatility. The 523’s design makes it especially suitable for metering tiny media quantities and sampling. The Type 523 Valve Series’ completely new design features a special 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.
