Industrial Isolation Valves
- Isolation valves have been in the industry for a long time. They are used in a fluid handling systems that stops the flow of process fluid to a given place, either for maintenance or safety reasons. They can be used as a means to control a process flow – diverting the process flow from one system to another or when there is a need to connect a new equipment to an existing system.
- Ball valves uses a rotary ball design as the main component of the valve, they are easy to maintain and ideal for clean operations. They can be used for conditions with moderate pressure differences.
- Butterfly valves are designed in the form of a disc the operate perpendicular to the flow and are ideal for controlling flow. Having short face-to-face dimensions, they are suitable for installations at places with space constraints. Butterfly valves are also lighter compared to ball valves as their disc is lighter than the ball hence require less structural support.
- Gates valves function similar to a gate with a simple open/close movement. The disc is perpendicular to the flow direction, when the valve is opened, the discs is drawn up into the valve bonnet. Gate valves come with various disc types, the commonly used ones are: solid wedge, flexible wedge and split wedge type. They have good shutoff features, low pressure loss and are bidirectional (can be used in two directions). However, they are not suitable for regulating or throttling flow due to slow opening and closing speed.
- Pinch Valves are the ideal solution for isolating and regulating abrasive, corrosive and fibrous products. The Pinch Valve is being used more and more as an isolating valve or regulating valve for emulsions, sludges, dusts, gaseous materials, compressed air, powder, granulates, pellets etc.
