Parker Wafer Style Valve - Monoball Series

Parker’s wafer style valve Monoball series either isolates an instrument or sits between two process flanges to isolate a process line. It offers multiple advantages over traditional flange-to-flange single isolate ball valves such as space and weight saving.

Many applications use a large process valve to isolate an instrument valve such as a monoflange, which requires additional support and increases installation costs. A wafer style  valve can provide exactly the same function, but without these disadvantages.

All Parker wafer style monoball valves offer the option of captive studding, allowing the instrument valve to be removed for maintenance or replacement without shutting down the process line. The wafer style valves are available in four sizes, with 10, 15, 20 or 25 mm bores.
