Cryogenic Ball Valves

Parker Bestobell’s cryogenic ball valves are specially designed for use in liquefied gas production, transportation and storage. These valves are ideal where the customer requires excellent full flow characteristics and long term performance. The innovative design of the valve allows for full flow of media from filling stations and portable delivery systems with low pressure loss, resulting in no delay in filling time.

These ball valves feature an innovative free floating ball design that allows the force of upstream pressure to push the ball hard against the downstream seats.  The higher the pressure, the more seating force and torque is required to operate the valve.  

Available in Bronze and Stainless Steel, the ball valves feature a spring-loaded gland seal, which provides low torque level under both ambient and cryogenic conditions.  

Parker Bestobell’s cryogenic ball valves are designed to eliminate leakages, maximise lifetime operation and reduce maintenance costs.
