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.
The normally open type is open at all times except when it needs to be closed. The normally closed type is blocked at all times except when it needs to be opened.
Bray is one of the global valve companies in South Africa. This company offers its services in several industries such as oil & gas, mining, power, water & wastewater and desalination applications, among others. It has a wide array of certifications that includes Lloyd’s Register Quality Assurance ISO 9001, EC Certificate of Quality System Approval and Pressure Equipment Directive 97/23/EC Quality Assurance Module H, among others.
Bray offers two kinds of solenoid valves, the Series 63 and Series 62. The Series 63 can come in NPT or IP65 DIN connections with single or dual coils. This has a temperature range of -13°F (-25°C) to +140°F (+60°C) for the AC and -13°F (-25°C) to +77°F (+25°C). The pneumatic post is ¼” NPT with a standard operating speed of 10 cycles per minute and a continuous duty cycle.
On the other hand, Series 62 is a poppet type valve that can be used as direct-acting or spring return actuators. It has a temperature range of +5°F to +140°F (-15°C to +60°C) with a continuous duty cycle. Its electrical connections are ½” NPT and DIN housing with cable gland M15 by 1.5. This type is manually overridden in case of power failure. Direct-mounted, Series 62 is suitable for dry or lubricated air or inert gases.
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.
