✔︎ Integral Metal Seat
With our exclusive HVOF RiTech® coating process, the integral seat in ValvTechnologies’ rotary operating valves are resistant from the attack of abrasive magnetite or ferrous oxides 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 3″ 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.

✔︎ The Xactrol® product group unites ValvTechnologies’ zero-leakage technology with special designs that allow rotary modulating control. From the Mark I’s design that features a characterized upstream seat to the Mark III’s precision engineered stacked disks, the Xactrol® allows the customer to combine precise flow control with tight shut-off. The Xactrol® is typically used in applications where minimum flow and relatively high differential pressures are required.
