Ball valves for cryogenic services, available with metal or soft seats, for temperatures down to -200°C, 2 or 3-piece Split body construction with Floating or Trunnion ball.
Ball valves for cryogenic services available with metal or soft seats for temperatures from -200°C to +700°C.
The SAT CRIO model is the extension of the SAT model down to the low temperature.
The design philosophy involve unique tecnica solutions to meet the best reliability as many field applications have demonstrated.

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.
Only Grafoil® gaskets are used, inherently resistant to high temperatures.
The backseat springs allow automatic body cavity pressure relief.
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 hard coated with most advances system, if necessary.
Metallic or polimeric seats are loaded with springs on both valve sides, also in floating ball construction for a full bi-directionality and automatic body cavity relief.
All valves are provided with stem cryogenic elongation communicating with valve body.
Like all PENTA production, SAT CRIO valves can be equipped with metallic seats in Pentafite or with polymeric seats, for lower working temperature, in both cases pre-loaded with springs, allowing the creation of valves with ZERO LEAKAGE.
SAT CRIO valves are available with Floating or Trunnion mounted ball, with reduce or full bore and all valves are provided with automatic body cavity pressure relief arrangement as like as cryogenic stem elongation.
