C-Type Valve manufacture

C-Type Valve manufacture

C-Type Valve manufacture


we came across in the specification, the ship owner requirements to "Design pressure of deck piping 40barg and lower design temperature -55°C. All cargo isolation valves shall be top entry cavity free torque seated eccentric c‐type ball valves.
cryogenic applications LNG cargo handling system, understand only one manufacture supplying this type of valves, if anyone knows other european or USA manufacturers , please help to advice me the company to contact them for more details, thank you in advance.


RE: C-Type Valve manufacture

Ship spezifications to be fulfilled for a builder/owner and a specified authority, will, as you presume, be limited to the producers that both comply and will be acknowledged by all as accepted certified valves.

Thus it is more to find the answer to this (easiest is to ask if the owner has prequalified producers or have preferences), more than find a new supplier and try to qualify an earlier untried producer.

But yes, on world-wide basis, there is always competition. Best way is a net or phone search.

RE: C-Type Valve manufacture

Top entry is the tough part. I’ve worked on a lot of projects that had a similar requirement, but ultimately the specifications were changed to accept a 3 piece valve instead of top entry.

White Paper - How ESI is Helping Move New Medical Device Product to Market Quicker & More Cost Effic
Early Supplier Involvement has long been a strategy employed by manufacturers to produce innovative products. Now, it almost seems like a necessity. Because decisions made in the design phase can positively affect product quality and costs, this can help add value to OEM bottom lines. This white paper will discuss many facets of ESI, including why it’s so valuable today, what challenges limit the benefits of ESI, how cost is impacted, and more. Download Now
White Paper - Moving to a Driverless Future
This white paper describes what we see as the best practices to support a sustainable engineering process for autonomous vehicle design. It exposes how to use simulation and testing in common frameworks to enable design exploration, verification and validation for the development of autonomous cars at a system, software and full-vehicle level to drive a mature product development process for automated driving.
