2602/2702 Series 2-Valve Mini Block & Bleed Manifold Valves
2602/2702 Series 2-Valve Mini Block & Bleed Manifold Valves
Key Features
- 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 - Valves are located on the top to fit into compact spaces and two holes are
provided for mounting, venting is to the left - 100% helium leak tested to 1 x 10-4 ml/s for guaranteed performance
and reliability - Soft tip valves feature a patented Delrin® non-rotating soft tip stem, and a
back-up metal-to-metal seal (U.S. Patent 6,820,857) - 2602 Series hard seat valves have 10,000 psi pressure rating @ 200 °F
- 2702 Series soft tip valves have 6,000 psi pressure rating @ 200 °F
- Blow-out proof stem provides a secondary stem seal in the full
open position - FKM o-ring seal and PTFE back-up ring below the stem threads to protect from
corrosion and galling; PTFE or Grafoil® packing optional - All stems are 316 stainless steel
- Stem and bonnet 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)
- Patented body-to-bonnet, metal-to-metal seal is designed to significantly
increase the pressure range of the valve (U.S. Patent 7,758,014)
