I'm reaching out to inquire about two specific items with a nominal bore size of 50mm and 200mm, both designed to handle a working pressure of 16 Kg/cm2. Could you please provide details on manufacturing and delivery timelines for these items? If these particular models are not available, I would appreciate it if you could suggest any suitable alternatives. Your assistance in this matter would be greatly valued, and I look forward to your prompt response.
