Reliable & Efficient Cryogenic Valve Solution

The NG Series check valves are crafted for optimal performance in LNG and cryogenic industrial systems. With a polished 316L stainless steel body and robust PTFE and metal-to-metal sealing, these valves offer low pressure drop and leak-free operation. Their compact, spring-loaded design makes them suitable for challenging environments, ensuring safety and efficiency during tanker loading, piping, and storage operations.

Versatile Installation Options

Whether your system requires threaded or welded end connections, the NG Series adapts seamlessly thanks to its flexible connection types: Female NPT and socket weld. Designed for use in horizontal or vertical positions, the valves support easy integration into existing cryogenic piping infrastructures, offering reliable isolations and backflow prevention for LNG and other industrial gases.

FAQ's of Rego LNG Check Valves NG Series:

Q: How do I install the Rego LNG Check Valves NG Series in my cryogenic system?

A: The NG Series check valves can be mounted in either horizontal or vertical positions and support threaded (Female NPT) or welded (socket weld) end connections. Ensure correct port size selection and align the valve with flow direction, following uni-directional flow requirements for optimal performance.

Q: What makes these valves suitable for LNG and cryogenic gases?

A: Constructed from 316L stainless steel with Inconel springs and PTFE/metal-to-metal sealing, these valves withstand extreme temperatures from -196C to +60C, providing bubble-tight shutoff and corrosion resistance essential for safe cryogenic service.

Q: When should I use a spring-loaded check valve in LNG applications?

A: Spring-loaded check valves like the NG Series are recommended when you need automatic backflow prevention, reliable sealing, and low pressure drop in LNG transfer, tanker loading/unloading, and cryogenic piping systems.

Q: Where are these check valves commonly installed?

A: These valves are typically used in LNG transfer systems, cryogenic distribution piping, tanker loading and unloading facilities, and other industrial gas applications requiring secure and efficient flow control.

Q: What is the process for ensuring a bubble-tight seal?

A: Each NG Series valve is designed and tested to meet ANSI/FCI 70-2 Class VI standards, ensuring bubble-tight leak rates with their PTFE and metal-to-metal sealing technology, suitable for high-integrity gas containment.

Q: How does using this valve benefit my system?

A: The NG Series offers reliable automatic operation, minimizes pressure drop, resists corrosion, and prevents leakage, enhancing operational safety, reducing maintenance, and supporting efficient LNG handling.
