MAXI-Check I (MCI)
Ball Check and Isolation Valve
Shown
MCI150-50-RL-HW-ANSI300
APPLICATION
The UPWEY MAXI‐Check I valves are designed specifically for slurries, dewatering or high pressure applications. The large port design prevents clogging while the HI‐WEAR seat offers a large sealing area.
The valve is normally located on pump discharge. In static situation the ball is held in the seat by back pressure. When the pump starts and pressure equalises, the ball then moves up into the ball bonnet where it is free to move and rotate on the media as it flows through the valve hence the ball will not attract scale build up. As the pump/media stops flowing, the ball falls into the seat and is once again held in the closed position by the back pressure. The hand wheel can then be wound to the closed position where the ball is mechanically held in the seat to create an isolation valve. The ball should show no signs of wear due to the fact it is free to roll or rotate on the flow and the seat is designed with minimum exposure to wear factors.
