Floating Ball Valves Water Transmission - High Pressure Line

Description

Floating valves are designed in accordance with ASME B16.34 and API 6D. Floating valves are available in pressure classes 150 to 2500 ASME, and in sizes ranging from ¼ inch to 10 inches. Available designs include one piece, two piece and three piece body configurations in both Forged and Cast materials with a variety of soft or metal seats. Special configurations which are available include 3-Way and fully jacketed body designs and Cryogenic and High temperature service fire safe capability. Floating ball valves are available in a wide variety of materials of construction including standard carbon and stainless steels, alloy 20, duplex and super duplex and the nickel based alloys such as monel, inconel and hastelloy. Floating ball valves are available with lever and gear manual operation as well as, a wide variety of pneumatic and electric valve automation systems.

Ball valves have many good points and are often considered superior to many other kinds of valves. Ball valves are very easy to use and can both maintain and regulate three things-high pressure, high volume and high flow of temperature.

Floating ball valves are normally seat supported and the seats are not self-relieving. Special designs are available for self-relieving seats.
