2603/2703/2604/2704 Series Manifold Valve
Brand: Noshok, IncSpecifications
- Combines isolating and venting in a single valve, eliminating the need for tubing and fittings
- Block valve isolates the downstream process fluids and the bleed valve exhausts upstream fluids enabling static pressure transmitters, switches or gauges to be removed without disturbing the permanent piping installation
- Block valve is located on the right and the bleed valve is located on top in a 90° orientation, venting is to the left
- 100% helium leak tested to 1 x 10-4 ml/s for guaranteed performance and reliability

- 2603/2604 series hard seat valves have 10,000 pressure rating at 200° F
- 2703/2704 series soft tip valves have 6,000 psi at 200° F
- Blow-out proof stem provides a secondary stem seal in the full open position
- All stems are 316 stainless steel
- All stem threads are rolled for strength and ease of operation
- One-piece bonnet with a metal-to-metal seal to the valve body below the bonnet threads
- Slotted spring pin to prevent accidental loosening
- Vinyl dust caps for bonnets and stems (non-packing)
