Stainless steel bolted bonnet OS&Y butt weld electric straight-through globe valves and flanged gate valves are one type of valve, which consists of five types: 6 inch globe valve, bolted bonnet globe valve, class 800 globe valve, OS&Y globe valve, SS globe valve. It consists of an electric actuator or a pneumatic actuator and a shut-off valve. Its valve body rotates around the center line of the valve body to open and close. The gate valve is mainly used in the pipeline to cut, distribute and change the flow direction of the medium. Structurally, certain measures have been taken to prevent the valve core from being stuck.

The fluid resistance is small, and its resistance coefficient is equal to the pipe length of the same length.
6 inch globe valve, bolted bonnet globe valve, class 800 globe valve, OS&Y globe valve, SS globe valve are easy to operate, quick opening and closing, easy to control over long distances.
The sealing surface material of the gate valve is widely used in plastics and has good sealing properties, and has been widely used in vacuum systems.
Simple structure, small volume, light weight, convenient maintenance, and the sealing ring is generally active, and the disassembly and replacement are relatively convenient.
When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium does not cause erosion of the sealing surface of the valve.
Options: seat: renewable seat available; stem: where contacts disc is hardened; back seat: enable to change packing under pressure; disc: parabolic disc upon request.
6 inch globe valve, bolted bonnet globe valve, class 800 globe valve, OS&Y globe valve, SS globe valve are widely used in different applications, such like, oil & gas field, petrochemical plant, refineries, power generation plant, marine, metallurgy, paper & pulp, water & waste water treatment, etc.
