Cast Steel Globe Valve

A cast steel globe valve is a commonly used pipeline valve used to control the flow of fluid media in pipelines. It typically consists of a valve body, valve cover, valve disc (or valve plate), and valve stem. Its operating principle is to control the flow of media by rotating the valve disc or valve plate to open or close the valve port.

GNEE Group supplies hundreds of valves, including ISO 9001 & API 6D dual-certified valves with a failure rate 75% lower than the industry average!

Cast Steel Gate Valve Product Features

• Simpler structure than gate valve, easier to manufacture and maintain.
• Sealing surface is less prone to wear and scratches, good sealing performance; no relative sliding between the valve disc and valve body sealing surface during opening and closing, therefore wear and scratches are not severe, good sealing performance, and long service life.
• Smaller valve disc stroke during opening and closing, therefore the height of the gate valve is smaller than that of the gate valve, but the structural length is longer.
• Larger opening and closing torque, requiring more effort to open and close, and longer opening and closing time.
• High fluid resistance; due to the more tortuous medium passage within the valve body, fluid resistance is high, resulting in high power consumption.
• Medium flow direction: When the nominal pressure PN≤16MPa, generally co-current flow is adopted, with the medium flowing upward from below the valve disc; when the nominal pressure PN≥20MPa, generally counter-current flow is adopted, with the medium flowing downward from above the valve disc, to increase the sealing performance. During use, the medium in the gate valve can only flow in one direction and cannot change the flow direction.
