Noshok 400 Series Hard Seat Needle Valve
400 series standard needle valves have a hard seat and blow-out proof stem that provides a secondary stem seal in the full open position. All stems are 316 stainless steel and all stem threads are rolled for strength and ease of operation. Other features for the 400 series include a one-piece bonnet with a metal-to-metal seal to the valve body below the bonnet threads and a slotted spring pin to prevent accidental loosening.
