Ball valves are on/off switches with a quarter-turn action. A pivoting ball in the centre of the valve controls the flow of liquid or gas media. The pivoting ball is called a rotary ball and has a hole (a bore) in the centre. A stem on the top of the ball rotates to open or close the valve. This is a valve suitable for valve automation in South Africa.
Water valves control the flow and temperature of water through pipes and plumbing fixtures. The valves control constant flow and volume when properly installed and operating. Water valves are made of brass, plastic, stainless steel, bronze, cast iron, and galvanised pipe. We offer this type of valve for valve automation in South Africa.
A gate valve, also known as a sluice valve, is a type of valve that opens by lifting a barrier out of the fluid’s path. Gate valves take up very little space along the pipe axis and barely restrict fluid flow when fully opened. The gate faces can be parallel, but they are usually wedge-shaped.
A globe valve, as opposed to a ball valve, is a type of valve used to control flow in a pipeline that consists of a movable plug or disc element and a stationary ring seat in a generally spherical body.
A check valve, non-return valve, reflux valve, retention valve, foot valve, or one-way valve is a valve that usually allows only one direction of fluid flow through it. Check valves are two-port valves, which means they have two openings in the body, one for fluid entry and one for the fluid exit.
Plug valves have cylindrical or conically tapered “plugs” inside the valve body that can be rotated to control flow through the valve. When the valve is open, the plugs in plug valves have one or more hollow passageways running sideways through the plug, allowing fluid to flow through the plug.
