150-600#

Flexibility in Action Get outstanding flexibility and reliability in the lower pressure class rage. Eraway's V1-2 flanged valves come in more sizes – you can put superior performance and long life where they are needed, in virtually any cast or forged material. Specify them with special end connections. Order them with the purge ports you need – and cavity fillers, cryogenic stem extensions, fugitive emission bonnets…all these options can be added to the valves that feature HVOF RiTech® hard coatings as standard – and absolute zero-leakage warranty.

- Integral metal seat. With our proprietary HVOF RiTech® coating technology, the integral seat in Eraway's’ valves is resistant to the attack of abrasive magnetite and ferrous oxides that may be seen in the steam flow.
- Body seal ring. Eraway's employs a field proven seal ring technology to ensure sealing under all operating conditions, up to 1400°F. The body seal ring is loaded at a pressure higher than 20,000 psi. In addition, valves sized three inch and above contain a secondary Grafoil seal to further guarantee reliability
- Patented coating process. The sealing surfaces are overlaid with tungsten or chromium carbide using our exclusive HVOF RiTech® process. These surfaces have a hardness of 68 – 72 Rc to allow long periods of operation in the most severe conditions.
- Live-loaded gland area. The V Series’ sealing design features a four stud, live-loaded assembly designed for heavy industrial applications. The sealing material is high purity Grafoil® surrounded by stainless steel wire mesh anti-extrusion rings. The six Belleville® springs (per stud) provide constant load pressure through extreme thermal shocks and prevent wear leaks in high-cycle service.
- Blow-out proof stem design utilizes a one piece, hard-faced, blow-out proof stem that is inserted through the inside of the body cavity eliminating the possibility of blow-out through the gland area.
- Through conduit design: No tortuous flow path. When open it has the highest possible Cv’s. Minimized wear & tear. Benefit: Eliminated vibration, reduced maintenance
- Fixed position – quarter turn: No seating torques required. Benefit: Minimized stem wear, lower cost of ownership
- 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
- Simplicity of design: Designed for ease of installation & maintenance. Benefit: Easily actuated, increased system reliability, increased efficiencies, ease of use, reeduced maintenance
- Stringent testing: Every valve is tested, documented & serialized. Benefit: Increased reliability, increased safety, total traceability
