Ball Valves

ball valves sm

Ball Valves are generally a bi-directional valve intended for on-off applications used in a number of different industries.  Some of these include water, oil, gas, chemical, pharmaceutical, mining just to name a few.  Ball valves have many good characteristics such as positive tight shut off, high flow rates, easy to automate, and low maintenance cost.

Ladish Valves ball valve product line are manufactured as full port with flanged ends.  Pressure classes include 150 through 600. From our Houston, Texas manufacturing facility, we manufacture ball valves to be used in severe corrosion resistant services.  These valves are made from bar stock in exotic and high nickel alloys such as hastelloy, inconel, monel and nickel.  Additionally Ladish can supply cast valves in the following materials: CF8M, CF3M, CF8, CF3, CK20, CG8M, CF8C, CN7M, CW12MW, CY40, CW6MC, N12MV, N7M, M35‐1, CZ100, CD3MN and many others.
