Casting Steel Trunnion Flanged Ball Valve
JOXN casting steel trunnion flanged ball valve has a higher pressure rating and is therefore better suited for high-pressure applications. Our trunnion ball valve is a type of valve that uses a ball held in place by two trunnions, whose design allows the ball to be easily opened and closed. A spring holds the seat in place, ensuring a good seal for the flanged ball valve.
