Welker JET® Control Valves
Welker began with control valves and is still recognized for control valve designs that offer unlimited flexibility. The Welker Jet® Control Valve offers a design that fits into conventional piping configurations, an insert style that fits between two standard pipe flanges and a new top-entry style that provides ease of maintenance while leaving the valve body in the pipeline. The straight through flow path and high-recovery design make
the Welker Jet® applicable in all types of gas control installations. Download Welker Jet Handbook. More information.
