forged steelFlange globe valveJ41H
forged steelFlange globe valveThe opening and closing component is a plug type valve disc, with a flat or conical sealing surface, and the valve disc moves in a straight line along the centerline of the fluid. According to the movement of the valve disc, the change in the valve seat opening is directly proportional to the stroke of the valve disc. Due to the relatively short opening or closing stroke of the valve stem and its highly reliable shut-off function, as well as the proportional relationship between the change in the valve seat opening and the stroke of the valve disc, this type of valve is very suitable for regulating flow. Therefore, this type of valve is very suitable for cutting off, regulating, and throttling purposes. Forged steel flange globe valves are widely used in industries such as environmental protection, power generation, chemical engineering, petroleum, and heat treatment. They are suitable for a wide range of temperatures and pressures, but are generally more common in medium and small diameter pipelines.

Overview of characteristics of forged steel flange globe valve:
1. During the opening and closing process, the contact area between the sealing surface of the valve disc and the sealing surface of the valve body is much smaller than that of the gate valve, resulting in wear resistance, abrasion resistance, good sealing performance, and long service life.
2. Small work schedule, low opening height, and short opening and closing time.
3. Good process performance, easy operation, maintenance, and installation.
