Standard ValvTechnologies’ 4yr zero leakage warranty in steam and water applications

Longer Service Life - Absolute Zero-leakage

ValvTechnologies’ 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.

Features

  • Integral metal seat. With our proprietary HVOF RiTech® coating technology, the integral seat in ValvTechnologies’ valves is resistant to the attack of abrasive magnetite and ferrous oxides that may be seen in the steam flow.
  • Body seal ring. ValvTechnologies 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.
