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
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)
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)
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)
