Why Sesto?

Precision Machined Forged Body
The forged body eliminates the possibility of leakage due to poor castings. Precision finish machining keeps tight tolerances to ensure secure assembly for high pressure,critical applications.

Ball/Seat Lapping
Lapping seats to the ball ensures tight tolerances, improving shut-off sealing capability while lowering torque requirements.

Guided Seat Design
The guided seat design allows for flexibility in materials of construction (end closures vs. seats vs. body), customizable spring configurations for specific pressure relief set points, and ease of maintenance. This design also ensures better concentricity between sealing components to improve sealing performance.
