Floating Ball Valves – 1/2"–8", 1PC/2PC/3PC Designs
J-VALVES floating ball valves cover 1/2" to 8" (DN15-DN200), Class 150 to 2500, in 1-piece, 2-piece and 3-piece constructions with flanged, threaded (NPT/BSP), socket weld and butt weld ends. Soft-seated designs deliver bubble-tight shutoff for oil & gas gathering, petrochemical, water and HVAC lines; extended-stem and high-platform versions accept pneumatic or electric actuation.

Floating ball valves FAQ
Q1 Floating vs trunnion ball valve - which to choose?
For bores up to 8" and typical class ratings, floating ball valves are the cost-effective choice; above that, or for high pressure, choose trunnion mounted type.
Q2 What end connections are available?
Q3 Are extended stem or high platform versions available?
