The main characteristics of internal thread gate valves produced by RTV Ruitong Valve, Z15W stainless steel internal thread gate valves, and American standard internal thread gate valves.
The opening and closing part of Z11H internal threaded gate valve is a plug shaped valve disc, with a flat or conical sealing surface. The valve disc moves in a straight line along the centerline of the fluid. The movement forms of the valve stem include the lifting rod type (valve stem lifting, handwheel not lifting), as well as the lifting rotating rod type (handwheel and valve stem rotating together to lift, nut installed on the valve body). The corrugated tube globe valve is only suitable for fully open and fully closed, and cannot be adjusted or throttled.
The opening and closing part of the thread gate valve is a plug valve, the sealing surface is flat or conical, and the valve flap moves straight along the centerline of the fluid. The motion form of the stem has the lifting rod type (the stem lift, the handwheel not lifting), also the lifting and rotating rod type (the handwheel and the stem rotates with the lift, the nut is located on the body).
Design characteristics of internal threaded gate valves
The structure is simple, and manufacturing and maintenance are relatively convenient.
Small work schedule and short opening and closing time.
Good sealing performance, low friction between sealing surfaces, and long service life.
