Features of High Quality Cryogenic Ball Valves

Durable

High-quality cryogenic ball valves use 316L or cryogenic alloy bodies with a service life exceeding 10 years.

Precision Sealing

Valve core and seat tolerance ≤0.05 mm, lip seal achieves zero leakage.

High Pressure Resistance

Valve body can withstand pressures up to 25 MPa, three-piece structure ensures long-term safety under high pressure.

Easy Maintenance Design

Side-entry structure facilitates valve core and seal replacement, making installation and maintenance more convenient.

FAQ

Q: How to clean?

A: High Quality Cryogenic Ball Valves can be cleaned using a low-temperature compatible cleaner to rinse the valve body and ball.

Q: Installation Precautions?

A: Keep the pipeline horizontal to avoid stress concentration.

Q: Are the parts replaceable?

A: Yes. The ball, seat, and seals are removable and replaceable; parts are available from the factory.

Q: Maintenance Frequency?

A: We recommend checking the seals and lubrication every 6-12 months. We provide a detailed maintenance guide.
