Mars “V” port control valves are available with 30 Degree V, 60 Degree V or 90 Degree V Notch Ball. V port ball valves offer better and more consistent control than traditional round ported ball valves. We offer these valves with the control port cast and machined into the ball, not in the seat. This allows for much better flow characteristics and eliminates the need to replace seats. The 30 option allows for finer tapered control throughout the valve rotation and the 60 & 90 offers a larger Cv in addition to controlled flow. The PTFE and Stainless Steel re-inforced seat is standard to our V port ball valves, it offers both strength and superior sealing properties.
