Forged steel globe valve

Forged steel flange stop valve J41H
Forged steel flange pieces of the gate valve is the valve plug type, sealing surface flat or cone, fluid along the centerline of the valve for linear motion. According to the valve flap in this form of movement, the valve seat through the mouth of the change is proportional to the disc stroke. Because of the valve stem to open or close the trip is relatively short, but very reliable cut off function, and because changes in the valve seat and the valve stroke is proportional, is very suitable for flow regulation. Therefore, this type of valve is very suitable for cutting or regulation and throttle. Forged steel flange valve in the environmental protection, power generation, chemical industry, petroleum, heat treatment and other industries in the use of very common, applicable to a wide range of temperature, pressure, but generally in the medium and small diameter of the pipeline is more common.
Overview of forged steel flange globe valve:
1, in the process of opening and closing, the valve sealing surface and the sealing surface of the body contact area is much smaller than the gate valve, so wear resistance, abrasion resistance, good sealing performance, long service life.
2, the working stroke is small, the opening height is low, the opening and closing time is short.
3, process performance, operation, maintenance, installation is relatively simple.
