Mueller 4 Bolt Check Valves

Four-bolt check valves feature forged brass bodies that exceed the most stringent quality standards in the industry.

The four-bolt flanges allow easy removal and reassembly of internal components. Suitable for either horizontal or vertical installation, the “Y” type design provides increased flow capacity and minimal pressure drop.

The non-asbestos gasket material and O-ring seal ensure absolute seal integrity while heat-stabilized PTFE seats provide a positive seal across wide temperature ranges.

Our four-bolt check valves also feature back pressure shutoff at low pressure differentials and special springs for various differential applications.
