Valv Technologies - Model V1-R -5/8"-4" Metal Seated Valve

• Sizes: 5/8” – 4”
• Pressure Classes: ASME / ANSI Class 3100
• Materials of Construction: Carbon steel (A105) – Standard, Alloy steel (F22, F91) – Standard
• In Compliance: ASME B16.34
• PED: Nuclear ASME III Class 1, 2 and 3
• Nuclear Safety Related – 10CFR50 Appendix B: SIL
• End Connections: Socketweld, Buttweld – Standard
• Shutoff: Absolute Zero-Leakage Shutoff

1. Simplicity of design: 4-piece valve assembly designed for ease of removal while connections remain inline. Field testable after repair, prior to insertion
2. Through conduit design: No tortuous flow path. When open it has the highest possible Cv’s
3. Fixed position: Quarter turn: no seating torques required.
4. Hardened blowout proof stem: One piece, inserted through the body & shouldered
5. Metallic body seal ring: Increases body integrity by eliminating external leakage.
6. Live load packing gland: Minimum four bolt configuration with shallow stuffing box. Ensures consistent torque at variable pressures & temperatures
7. Hard coated & mate lapped seats: High Velocity Hydrogen Fuel (HVHF) chrome carbide hard coating with Rockwell C of up to 72. Mate-lapped seats
8. Seat designs: Hard coated, both ball and integral downstream seat to the end-cap to eliminate a potential leak path
9. Stringent testing: Every valve is tested, documented, and serialized
10. Four-year warranty: The very best in the industry. Covers internal seat leakage as well as external through the packing and/or body seal.

• 4-piece assembly that allows for removal, while end connections remain in-line. Maintenance can now be made without the need for cutting or welding. Benefit: Increased efficiencies, ease of use, reduced maintenance costs
• Through conduit design: No tortuous flow path. When open it has the highest possible Cv’s. Minimized wear & tear. Benefit: Minimized wear & tear, reduced vibration, reduced maintenance
• Fixed position – quarter turn: No seating torques required. Benefit: Improved safety
• Hardened blowout proof stem: One piece, inserted through the body & shouldered. Eliminates the weak link of collared & pinned designs. Benefit: Improved safety
• Metallic body seal ring: Increases body integrity by eliminating external leakage. Benefit: Improved reliability, zero-leakage shutoff
• Live-loaded packing gland: Minimum four bolt configuration with shallow stuffing box. Ensures consistent torque at variable pressures & temperatures. Benefit: Increased reliability
• Hardcoated & mate lapped seats: High Velocity Oxygen Fuel (HVOF) RiTech® chrome carbide hardcoating with a Rockwell C of up to 72. Mate-lapped seats.
  Benefit: Wear & corrosion resistant, increased reliability, zero-leakage shutoff
• Seat designs: Hardcoated, both ball & integral downstream seat to the end-cap to eliminate a potential leak path. Benefit: Increased reliability
• Stringent testing: Every valve is tested, documented & serialized. Benefit: Increased reliability, increased safety, total traceability
