Valvtechnologies' flanged ball valves have a bubble-tight shut-off to ANSI FCI 70-2. This is achieved with an integral downstream seat, which is completely protected from the flow path. Seat testing is 100% on all valves. The valves are designed to operate in high temperatures, under high pressures, in corrosive environments. Due to their robust design, the valves are supplied with a 4-year guarantee.
Rocket applied metallic hard coatings make the valves highly resistant to corrosion and abrasion, even in temperatures up to 965°C. Each valve is serialised and has identity marks on all pressure containing parts and material certificates and test results are maintained.
A variety of pneumatic double-acting and spring return types, electric motors or hydraulic actuators in addition to gear operators are available, all sized, mounted and tested to meet the required specifications.
Various options are available including bi-directional sealing, control trims, special end connections and hard coatings, various materials of construction and pressure classes above ANSI 600. If required, wafer styles and sizes larger than 400 mm can also be supplied.
