PENTAFITE SEATTECHNOLOGY

PENTAFITE is a metallic compound with metallic matrix and fine dispersion of solid lubricant in-side. It is obtained by a manufacturing process similar to sintering with which, starting from fine powders of the single componenet, is possible to produce the metallic rings that form the seat insert for our metal seated ball valves for services with high temperature, high pressure or with combina-tion pressure/temperature higher than tolerable limits for polymeric material.

What matters is inside

PERFECT TIGHTNESSElastic properties of PENTA-FITE seat material allow the automatic adaptation of seats against ball shape, eliminating machining im-perfections. This is the way to eliminate any possible leak-point and achieve the per-fect tightness.

LOW VALVE TORQUEThe presence of the solid lubri-cant dispersion inside the me-tallic matrix, reduces the seat to ball friction factor and also the valve torque. For the same reason seizure or galling be-tween seat and ball surfaces are eliminated even when the working temperature is high.

EASY MAINTENANCEBecause 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.

GAS TIGHTNESSThe 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.
