Noshok 600 Series Hard Seat Block & Bleed Needle Valve
600 series block & bleed needle valves have a hard seat and allow pressure to be bled off without disturbing the permanent piping installation. This feature allows for quick and easy removal or replacement of instruments. The 600 series has a 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 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.
