  • The characteristics of Casting valves

    Casting valves are valves made by casting. Generally, the pressure ratings of cast valves are relatively low (such as PN16, PN25, PN40, but there are also high-pressure ones, which can reach 1500Lb, 2500Lb), and most of their calibers are above DN50. Forged valves are forged and are generally u...
