PENTAFITE Seat technology

It is a metallic compound with metallic matrix and fine dispersion of solid lubricant inside. It is obtained by manufacturing process similar to sintering with which is possible to produce the metallic rings that form the seat insert for our metal seated ball valves.

Most important properties of PENTAFITE metal seats

1. Perfect Tightness: elastic properties of PENTAFITE seat material allow the automatic adaptation of seats against ball shape, eliminating machining imperfections. This way it is possible to eliminate any possible leak-point and to meet the perfect tightness.

2. Low valve torque: the presence of the solid lubricant dispersion inside the metallic matrix, reduces the seat to ball friction factor and also the valve torque. For the same reason seizure or galling between seat and ball surfaces are eliminated even when the working temperature is high.

3. Easy maintenance: because it is not necessary for additional machining to adapt seats against the ball (You do not have to lap the seat against to the ball) valve assembly and maintenance are very easy when PENTAFITE metal seats are used.

4. Gas tightness: the presence of the solid lubricant inside allows the PENTAFITE material to reach very high working specific pressures resulting in perfect tightness when high pressure gases must be stopped.

This material is the strength of Penta and allows us to be competitive on metal seated ball valves market with a unique solution for services with high temperatures, high pressures or combination pressure/ temperature higher than tolerable limits for polymeric materials.
