Union Bonnet Needle Valves, NU and NUH Series

Feature a one-piece forged body

NU and NUH Series Union Bonnet Needle Valves feature a one-piece forged body with a working pressure of up to 10,000 psig. The union bonnet design prevents accidental disassembly. The two-piece stem design includes cold-rolled upper stem threads and a hardened lower stem for strength and smooth operation. The upper stem thread lubricant is isolated from system media. The non-rotating lower stem moves linearly up and down instead of rotating, minimizing packing abrasion and reducing friction between the seat and tip. A safety back-seating seal is provided in the fully open position. Available in various connection types, sizes, and handle colors. The handle is securely fastened with double lock-pins.
