Split body ball valve for mild-high temperatures from -50°C to +400°C with soft or metal seats.
The AP ball valves are designed to be used in a wide range of applications and for temperatures from -50°C to +400°C.
The AP series provides some design solutions adopted for the most performing models of our production, such as SAT and 3W series, that today are still unique on the market: the self-lubricated metal seats in PENTAFITE, pre-loaded with springs, the special expanded graphite seals and the “live loaded” stems.

The double ring system with loading nuts allows the correct stem gasket pre-loading and the adjustment to recuperate wearing and clearance for different thermal dilation between stem an body
Only Grafoil® gaskets are used, inherently resistant to high temperatures: no polymers are used
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.
Very high precision grounded balls are produced inside and then they are hard coated with most advanced systems
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.
Over the years Penta has managed to maintain these product qualities even making the AP model available on a larger scale through the mass production of some components, such as the metal seats in Pentafite, which make the AP model ball valves the most competitive on the market.
The use of metal seats in PENTAFITE allows the creation of ball valves with metal seats with ZERO LEAKAGE, easy to maintain, without the need of adaptation between seats and balls and with 40% reduced operating torques compared to standard metal seats solutions.
The same attention is paid to verifying the degree of tightness towards the outside through the TUV certification of compliance with the limits imposed by the German TA-LUFT regulation and ISO 15848-1 certification.
