1. Integral Metal Seat. With our patented 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.
2. Body Seal Ring. ValvTechnologies employs a field proven seal ring technology to ensure sealing under all operating conditions, up to 1400o F. The body seal ring is loaded at a pressure higher than 20,000 psi. In addition, valves sized 3 inch and above contain a secondary Grafoil seal to further guarantee reliability
3. 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.
4. Live Loaded Gland Area. The V1 Series gland packing design features a four stud, live-loaded assembly designed for heavy industrial applications. The packing material is high purity Grafoil® surrounded by Carbon Fiber / Inconel anti-extrusion rings. The six Bellville springs (per stud) provide constant load pressure through extreme thermal shocks and prevent wear leaks in high cycle service
5. Blow-out Proof Stem. ValvTechnologies 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
