- Compact design is ideal for installations with limited space, such as
behind panels or in cabinets - Designed for use with differential pressure transmitters incorporating
two isolation valves and an equalizing valve in differential pressure
measurement - 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) - 3610 Series hard seat valves have 10,000 psi pressure rating @ 200 °F
- 3710 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
- 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
- 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)
*If a packing option is chosen, maximum pressure rating is 6,000 psi. Refer to the "Pressure vs. Temperature: Packing Style with Compatible Fluid" .pdf on the right-hand side of this page.
