Cryogenic Forged Steel Check Valve

Camtech Cryogenic valves are specially designed for gas treatment processes and storage and transportation of liquefied gasses such as LNG, liquid nitrogen, Oxygen,. Etc. These valves are required to be operated to give assured leakage rates. These valves which are recommended to use below -50⁰C up to -196⁰C.
Camtech manufacturing offers the cryogenic industry the most complete and technically advanced cryogenic forged steel check valves.

Camtech Cryogenic valves are specially designed for gas treatment processes and storage and transportation of liquefied gasses such as LNG, liquid nitrogen, Oxygen,. Etc. These valves are required to be operated to give assured leakage rates. These valves which are recommended to use below -50⁰C are designed with a extended bonnet which separates the operator and stem seal from the cold temperature. 12” gas column is a standard feature for these valves. Extended bonnet as per MESC SPE 77/200 & SPE 77/209 can also be given.

The main pressure containing components are treated with liquid nitrogen to stabilize dimensions and eliminate the stress caused by metal microstructure changes. Lip seals are used as a seals in these valves which are made up of different materials such as PTFE, KEL-F, etc, and it is self energized by an internal spring of stainless or Inconel alloy.

Camtech valves are inspected and tested In-House in accordance with BS 6364 to certify sealing performance in cryogenic conditions, when required by the customer.
