Gate, Globe & Check Valves
Gate, globe & check valves are some of the most widely utilised valve equipment within pipeline arrangements.
Commonly gate & check valves are used to prevent flow. Check valves being specifically utilised to prevent backflow in a system and provide protection to pipeline equipment whose flow preference may be in one direction only. Gate valves are generally utilised as an isolation valve to prevent or allow flow through a pipeline. Gate valves are commonly used within low pressure applications as they do have a tendency to “chatter” at higher pressure flows, they can however be effectively utilised in severe temperature applications.
Globe valves can be utilised as an off/on valve or as a flow regulating valve in throttling applications. Globe valves have two key features which allow them to be highly effective in throttling applications; a movable plug / disc and a valve seat which is parallel (rather than perpendicular to the fluid flow).
Gate & globe valves can be constructed in a variety of ways to ensure functionality and suitability for the desired service, such construction options include:
- Bolted or welded bonnets
- Pressure seal bonnet
- OS&Y stem
- Non-rising stem
- Oxygen service
