Metal seated ball valve for high temperatures (up to +720°), 2 or 3-piece body constriction available with Floating or Trunnion ball.
Metal seated ball valve for high temperature from -100°C up to +720°C
The SAT model is the PENTA valve construction that best suits a wide range of uses. The first aim of the design philosophy is to achieve maximum reliability, through the implementation of technical solutions that still today are unique on the market.

STEM TIGHNESS Unique stem seal design realized in Penta. The spring placed at the stem top gives the contact load for low pressure tightness and the adjustment for wearing and clearance for different dilatation between stem and cover.
GASKETS Only Grafoil® gaskets are used, inherently resistant to high temperatures.
STEM Stems are 100% oversized against expected torque at max. rating DP.
BOLTING AND FLANGES All flanges connections are designed according to ASME VIII Div.1 and ANSI B16.34.
BALL Very high precision grounded balls are produced inside and then they are hard coated with most advanced systems.
SEATS Metallic seats are pre-loading with springs for a perfect low pressure bubble tightness and to recuperate life wearing and different thermal dilatation between internals.
UPPER COVER All SAT/APT3 valves are provided with bolted upper cover for quick and easy stem assembly maintenance.
Like all Penta production, SAT valves are design to be equipped with metal seats in PENTAFITE allowing the creation of metal seat valves with ZERO LEAKAGE suitable for a wide range of services with working temperatures up to 720 ° C in continuous operation or 420 bar pressure. The typical elastic properties of Pentafite seats and the sully bolted construction allow an easy maintenance without necessary of additional lapping of the seats against the ball. Hard coated seats are also available. SAT valves are available with Floating or Trunnion mounted ball, with reduced or full bore and all valves are provided with automatic body cavity pressure relief arrangement.
