Longer Service Life. Absolute Zero-leakage Eraway's’ investment cast version of the V1-1 severe service isolation valves pay off in low-pressure drain applications with the elimination the typical high-maintenance linear valves and allows the customer to take advantage of the benefits that come standard with the zero-leakage warranty, ensuring long service life. The V1-3 is available in both full and reduced-port models and, like all of our V series products and just as important, our HVOF RiTech® hard coatings enables the same critical mate lapped sealing surfaces – making it impervious to erosive, corrosive and abrasive services.

- 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, reduced maintenance
- Stringent testing: Every valve is tested, documented & serialized. Benefit: Increased reliability, increased safety, total traceability
