Why Choose A CNG LNG LPG 3-Piece Cryogenic Floating Ball Valve?

The CNG LNG LPG 3-piece cryogenic floating ball valve is specifically designed for low-temperature gas applications requiring safe and reliable shutoff. Its floating ball design provides excellent sealing by allowing the ball to press against the downstream seat under pressure, ensuring tight closure. The 3-piece construction offers significant advantages in terms of maintenance—users can easily remove the center section for internal inspection or replacement without disturbing the pipeline. This design is ideal for cryogenic services like LNG terminals, CNG fueling systems, and LPG storage, where downtime must be minimized. The valve features extended bonnets to protect stem packing from cold temperatures and ensure operational integrity at temperatures as low as -196°C. Constructed with materials suitable for cryogenic conditions and tested to stringent standards, this valve ensures superior safety, easy servicing, and long-term durability in demanding gas service environments.
