NoShok 2070 Series 2-Valve Block & Bleed, Hard Seat Needle Valve
The NOSHOK 2070 Series 2-Valve Block and Bleed Hard Seat Needle Valve is a specialized instrument manifold designed to combine isolation and venting into a single, compact unit. This design eliminates the need for extra tubing and fittings, reducing potential leak points while allowing instruments to be safely removed or calibrated without disturbing the permanent piping installation.
Key Features:
High-Pressure Reliability: Features a 10,000 psi pressure rating at 200 F for the standard hard seat design.
Dual Valve Function: The block valve isolates the downstream process, while the bleed valve exhausts upstream fluids for safe instrument maintenance.
Bubble-Tight Integrity: Each unit is 100% helium leak tested to 1 x 10-4 ml/s to guarantee field performance.
Robust Stem Design: All stems are 316 stainless steel with rolled threads for high strength and smooth, gall-resistant operation.
Safety Engineering: Includes a blow-out proof stem for a secondary seal in the full open position and a slotted spring pin to prevent accidental bonnet loosening.
