Customer is asking for a 2" globe valve with ASTM B62 body with Bronze trim. Are there equivalent alternatives to propose? DUPLEX could do?Unfortunately service and fluid are unknown for now. Needle Valves i know it's not a proper question, without knowing what the valve is going to do and which fluid is going to regulate.what i want to know is if there are some materials that are universally considered like good alternatives to bronze.Filter We have found that the pricing for bronze valves for small diameter threaded is high, and for general service (we use for steam and water) we have moved to a forged steel valve with stainless internals. Bellow Seal Valve These valves are rated at a MUCH higher pressure (800 psi vs 300) AND are less expensive. Many manufacturers make both the bronze and forged, we use Powell, but have used Vogt, Velan, etx. Market and application - There is still for instance some producers that are producing low-priced bronze valves for common seawater/ship use; where for larger valaves or valves for higher pressures, requiring special castings or bar-stock, the bronze material could be replaced by other non-corrosive materials, or steel- /nodular iron if adequate.I do not believe there is a single answer to your question without specifying application details. Water Pump Control Valves As above, without further details, it's difficult to spec alternatives, but in general, the only alternatives we usually see for bronze is monel,Water Power Control Valves and we only see that in the trim. Price is obviously a factor. I've never really seen duplex as an alternative to bronze.
