GLOBE VALVES
Globe valves are primarily used as control valves where moderate control or regulation of flow is required. Globe valves are marked with flow direction arrows as they are recommended to be installed with flow and pressure under the disc. The amount of force to close a globe valve against pressure is much higher than gate valves but the stem travel distance is much shorter.

CHECK VALVES
Check valves are single direction flow valves used to allow unlimited flow in one direction and to restrain flow in the opposite direction. Check valves are normally designed for installation in horizontal lines but may also be used in vertical lines where the flow is upward under the disc.
Swing Check Valves
Swing check valves are straight through flow valves which work automatically. The disc swings from the seat upon exertion of fluid pressure on the upstream side. When the direction flow reverses, the reversal pressure and the weight of the disc close the disc against the seat, stopping backflow. This design allows the valves to remain closed even with no flow going through the valves.

BALL VALVES
Ball valves can be used to handle a variety of liquids, suspended solids and gases. Ball valves are suited for fluid flow requiring assured performance, tight shut off, constant torque and no maintenance.
Ball Valves Technical Information
Floating Ball Valves
Floating ball valves offer quick, quarter-turn operation, visual indication of the valve position, straight uninterrupted flow and compact size. The full bore design minimises pressure drop across the valve while maximising flow capability and throughput economy for general in line services.
