Improved throttling now available in more sizes

| By Chemical Engineering

Emerson Process Management

This firm has extended line sizes for the Fisher Control Disk valve (photo), which offers excellent throttling performance and is suitable for applications that involve fast processes and varying pressure drops. The valve’s control range is said to be twice that of traditional butterfly valves for better adherence to set point. The new sizes are designed for installation between ASME Class 150 or Class 300 raised-face flanges with flangless (wafer) or single flange (lugged) body designs. Face-to-face dimensions are in compliance with API 609 and MSS SP-68 standards. — Emerson Process Management, Baar, Switzerland
