Features/Benefits

Union Bonnet Design Ensures High Integrity Seal Under Severe Service Applications; Packing Below the Power Threads Protects Thread Lubricants from Media and Isolates the Lubricants from the Media; Dust Seal in the Packing Nut Protects Stem Threads from External Contamination; Stem Swivel Above the Packing Eliminates Entrapment Area and Increases Packing Life; 100% Factory Tested

Series/Model Information

Parker's U Series Union Bonnet valves are engineered for use at pressures up to 6,000 (414 bar) and temperatures as high as 1,200°F (649°C). The heavy duty design has a non-rotating lower stem that helps to extend packing life by removing stem rotation through the packing area. Stem packing below the threads isolates the thread lubricant from the flow, ensuring adequate lubrication regardless of the media.
