Solenoid Valve South Africa

Solenoid valves are valves that use electromagnetic actuators for opening and closing. These valves are used to control the flow of media in pneumatic and hydraulic fluid systems. The most common solenoid valves have “normally open” or “normally closed” versions.

Gate Valve Suppliers South Africa

Gate valves are shutoff valves that are best used in a fully open or fully closed position. The main parts of the gate valve consists of the valve body, seat, disc, stem, gland, and handle. The seat and stem are the major components that perform the shutting off of the media. Gate valves are not great fluid regulators as these kinds of valves are prone to valve disc vibration. These vibrations cause damage to the disc.

There is going to be an increase in demand for gate valves in the coming years because of the global need for these kinds of industrial valves. Valve buyers should grab this opportunity and look for great gate valve prices in South Africa.

Knife gate valves, in particular, will take the limelight due to their various applications particularly in pulp & paper, wastewater treatment, sugar-making, and chemical processing industries.
