ST – RAISED FACE PADDLE PLATES

6” 600# RF PLATE | 1” 1500# RF PLATE

Raised Face Paddle Plates

Raised Face Paddle Plates are used for flow metering or restriction applications, where the orifice plate is installed between ASME B16.36 flanges for flow metering applications or ASME B16.5 flanges for restriction applications. The assembled units are referred to as Orifice Flange Unions.
