Please introduce some of the more advanced pressure regulating valves used in natural gas stations
Thread Content
The company plans to build a new long-distance transmission station and would like to know what are the most advanced pressure regulating valves available today. The maximum pressure is 6.4 MPa; please give me your advice.
For relatively advanced pressure regulating valves used in natural gas stations, it is advisable to choose imported valves. Brands such as KTM, TYCO, and Gemmi from abroad have a track record of being used in domestic chemical plants. It is important to pay attention to the choice of the valve core and seat material when selecting valves; copper materials should not be used for valve cores in environments where natural gas is present. Secondly, after selecting a manufacturer, ask them to provide records of their use of identical devices under the same operating conditions, and conduct further inquiries; since the operating conditions you have specified are quite special, it is necessary to be cautious.
Pressure regulating valves in natural gas stations generally use self-acting valves for pressure regulation (usually to reduce and stabilize the pressure, thereby maintaining a constant output pressure; I’m not sure if that’s correct?) ), domestic self-acting control valves have a limited range of operational suitability; in situations with high pressure differences, it is advisable to use imported self-acting control valves such as those from Fisher and Metso, which have demonstrated excellent performance in natural gas applications. It is necessary to pay attention to the actual operating conditions of natural gas and make targeted selections.
Thank you for your answers:victory:
Currently, German RMG, Elster, Shanghai Feiao, and Chengdu Fisher Jiuan are quite commonly used in China
Has anyone used Tatarini?
Fisher models are better, offering high stability, but they require specific characteristics; especially for high flow rates, the choice of the main valve element is crucial.
