U Series Needle Valves Introduction Parker U Series Union Bonnet Valves have been engineered for use at pressures up to 6,000 (414 bar) and temperatures as high as 1,200°F (649°C). A non-rotating lower stem helps to extend packing life by removing rotation from the packing area. Stem packing below the threads isolates the thread lubricant from the flow, ensuring adequate lubrication regardless of the media. 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...
