Noshok 700 Block & Bleed Needle Valve
Noshok® type 700 block & bleed soft seat needle valves allow pressure to be bled off without disturbing the permanent piping installation, allowing quick and easy removal or replacement of instruments. They have 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.
