Parker Hannifin U Series Union Bonnet Valves

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.
