Mueller's 4-bolt check valves feature forged brass bodies that exceed the most stringent quality standards in the industry. The 4-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 4-bolt check valves also feature backpressure shutoff at low pressure differentials and special springs for various differential applications.
