Rotofold Ball Valve ManifoldThe Hoke Rotofold ball valve manifold has a unique design that utilizes quarter turn ball valves for blockingprocess impulse lines and performing equalizing functions. They also provide easy rod though of all passageswhen clean-out is necessary. PCTFE seats and Teflon® stem packing are easily replaced if maintenanceis required. The pipe by flange Rotofold design allows the manifold to be directly mounted to integral orificetransmitters by simply reversing the flanges and flange fittings. The pipe by pipe Rotofold design allows themanifold to be remotely mounted separately from the process.Technical DataMaximumOperating PressureOperatingTemperature Range6000 psig (414 barg)-65° F to +150° F (-54°C to +66° C)400 psig @ +300° F (28 barg @ +149° C)0° F to +300° F (-18°C to +149° C)Pressure Temperature CurvesPSI (BAR)Rotofold Pressure Temperature Curve6000 (414)5000 (345)4000 (276)3000 (207)2000 (138)1000 (69)00 50 100 150 200 250 300(-18) (10) (38) (66) (93) (121) (149)Fahrenheit (Celsius)HOKE, Inc.405 Centura Court • PO Box 4866 (29305) • Spartanburg, SC 29303Phone (864) 574-7966 Fax (864) 587-5608www.hoke.com • sales@hoke.comFeatures & Benefits• Flange can be reversed for direct mounting to anintegral orifice type transmitter• Connections on instrument side of block valves forbleeding and venting.• Replaceable PCTFE seats on all valves providelonger service life.• All media passages can be rodded for easycleaning.• ¼ turn handle provides visual indication of valvemode.• Mounting bolts and TFE gaskets are standard withflange models.• Cam handles provide error-proof sequencing ofvalves.• Mani-Mount mounting kit available for NPT pipestyle (see Mani-mount mounting system, page 17)Cam-Valve Interlocking Sequencing HandlesThe correct sequencing of opening and closing manifold valvesis critical to eliminating pressure transmitter damage due to overranging. By attaching cams to the equalizing and block valve handles,the inter-locking design assures proper initial service and transmitterzeroing during calibration.Cam kit 8200K5 can be field installed or factory assembled to themanifold at time of order. For factory assembled, add part number8200K5 to the end of the manifold part number.instrument manifolds
