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

Longer Service Life - Absolute Zero-leakage

Designed for severe service applications, V1‑1 valves are engineered to meet each customer’s specific requirements.

As the flagship of the ValvTechnologies product line, the V1‑1 sets the standard for metal‑seated ball valve performance. Its design features integral seats, RiTech® hard coatings, a blowout‑proof stem, and live‑loaded packing for long‑term reliability.

The V Series’ proven seat‑supported design delivers superior flow performance compared to linear‑operated valves with restrictive, complex flow paths. This robust construction provides the added safety margin needed to improve reliability, reduce downtime, and lower maintenance demands.

Engineered for leak‑free operation, optimized flow, and reduced total cost of ownership, V1‑1 valves are backed by an industry‑leading four‑year, zero‑leakage warranty.

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.
  • Backpressure protected sealing. Standard with the V1-1 valves, the design prevents the upstream spring from collapsing in a reverse flow condition, protecting the internals from damage and guaranteeing shutoff in the reverse direction.
  • Zero-leakage shutoff. ValvTechnologies tests every valve according to ANSI procedures, however, we toughen the standard and define zero-leakage as no detectable leakage of gas or a liquid for a period of three minutes or greater. The ValvTechnologies’ standard is zero drops and zero bubbles, guaranteed.
