NOSHOK 400 Series - Hard Seat Standard Needle Valves

NOSHOK STANDARD NEEDLE VALVES are the workhorses of the industry. The 400 Series’ metal-to-metal hard seat design is pressure rated to 10,000 psi @ 200 °F and helium leak tested to 1x10-4 ml/s for guaranteed performance and reliability. The all 316 stainless steel blow out proof stem provides greater service life and provides a secondary stem seal in the full open position. The stem and one piece bonnet threads are rolled for greater strength and ease of operation. The 400 Series feature stem seal below the threads to protect against corrosion and galling.
