Gate Valves- FAQ’s Answered

Gate valves are not recommended for flow throttling purposes, as doing so could potentially cause damage to the seats or wedge. These valves are optimally designed for applications involving complete opening or closing, making them ideal for isolation purposes.
Gate valves should not be employed at the end of a pipeline, commonly known as end-of-line duty. These valves are not engineered to handle the elevated pressure and flow conditions that typically manifest in this position. For end-of-line applications, it is advisable to use suitability-rated blanking flanges, a specialised type of flange designed to block and halt any flow through the pipeline's termination point.
Gate valves are operated using a variety of mechanisms. These include manual operation achieved through a handwheel or stem cap, allowing for remote control using a T-key or extension spindle. Additionally, automated operation is made possible by fitting intelligent actuators to the valve, providing efficient control without the need for manual intervention.
A gate valve, operating through multiple turns, is primarily designed for flow isolation. It utilises a travelling wedge that moves through the media, providing an unobstructed, clean bore when fully open. On the other hand, a butterfly valve, operating with a quarter turn, serves to isolate or regulate flow through a rotating disc in the flow path. Butterfly valves are specifically designed for clean media applications.

To ensure optimal performance and durability of gate valves, adherence to the following maintenance guidelines is crucial:

  • Operate the valve at least once a month, especially if it's not in frequent use, to maintain functionality and prevent potential issues.
  • Before commencing any maintenance, ensure the system's pressure is fully relieved to conduct safe servicing.
  • During valve removal from the pipework, meticulously reverse the installation steps, following the correct sequence to prevent damage.
  • When replacing the valve gate, carefully disassemble the top body (bonnet) and stem. Replace the existing gate with a new part, and securely reinstall the top body before refitting the valve into the pipeline.
