These linear motion valves are used to stop, start and control the flow of fluid. Unlike the perpendicular seating in gate valves, globe valve seating is parallel to the line of flow. All contact between seat and disc ends when flow begins. This provides the valve with effective throttling ability for flow regulation.
These types of valves consist of a spherical obstruction that is used for stopping and starting the flow of liquid or gas. They require a 90 degree rotation for opening and closing. When fully open, ball valves allow for unrestricted flow. In their fully closed position, they offer drop tight shut-off.
The butterfly valve derives its name from the wing-like action of the disc, which operates at right angles to the flow. This quarter-turn rotational motion valve is easy and fast to open and close. It is used to stop, start and regulate flow. Our butterfly valves utilise elastomer seats and seals. They can be used in wide-open or fully closed positions.
The check valve, also known as a non-return valve, is used in piping systems to restrict and stop backflow. The fluid that passes through a pipeline creates pressure and flow velocity that opens the valve and allows for unobstructed flow. On the flip side, the reversal of flow will cause the valve to close.
