Introducing a new addition to our V Series – the V1-R:
Our trusted V Series valve, now with ease of maintenance.
ValvTechnologies V Series valves are engineered to be leak-free and have a position-seated design, ensuring optimal flow while reducing overall cost of ownership. The new V1-R valve has a 4-piece assembly that allows for removal of the valve body and end cap, while the end connections remain in-line. Maintenance can now be made without the need for cutting or welding.
The new V1-R: experience enhanced performance, reduced downtime, and seamless service, all in one innovative solution.
- Simplicity of design: 4-piece valve assembly designed for ease of removal while connections remain inline. Field testable after repair, prior to insertion
- Through conduit design: No tortuous flow path. When open it has the highest possible Cv’s
- Fixed position: Quarter turn: no seating torques required.
- Hardened blowout proof stem: One piece, inserted through the body & shouldered
- Metallic body seal ring: Increases body integrity by eliminating external leakage.
- Live load packing gland: Minimum four bolt configuration with shallow stuffing box. Ensures consistent torque at variable pressures & temperatures
- Hard coated & mate lapped seats: High Velocity Hydrogen Fuel (HVHF) chrome carbide hard coating with Rockwell C of up to 72. Mate-lapped seats
- Seat designs: Hard coated, both ball and integral downstream seat to the end-cap to eliminate a potential leak path
- Stringent testing: Every valve is tested, documented, and serialized
- 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
