Choosing the right valve suppliers in South Africa can be a stressful task as you have a lot of them to choose from. Top valve companies often carry more inventory because they understand that their buyers need their products as soon as possible. Valve preventative maintenance and repair services are also part of their customer service. The best valve suppliers and manufacturers also offer some level of customization so buyers can get a quality product.
We have provided you with a list of the top valve manufacturers in South Africa. We added vital facts about the products these companies offer as well as other important information so that you can narrow down your choices.
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 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.
KSB is one of the world’s leading pump and industrial valve manufacturers with bases in South Africa. Its products and services are often used in water and wastewater, energy and mining industries.
KSB carries the Ecoline, Sicca, Staal, ZTN and Hera standard gate valves and knife gate product lines. The Ecoline gate valves feature flanged ends with bolted bonnet and metal seats. Depending on the model, these gate valves can have PN ranging from 10-40 with temperature ranges from -10 to 400 degrees Celsius.
The Staal product line can have either flanged or butt-weld ends with bolted bonnet. Its body can feature forged or welded 17% chrome seats. These can have a PN rating ranging from 10-100. These valves can withstand -10 to 530 degrees Celsius.
On the other hand, the Sicca product line has a pressure class ranging from ANSI Class 150 to ANSI Class 600. The valve sizes can range from ¼ inch to 24 inches. The temperature range these valves can endure is between 0 to 816 degrees Celsius. The ZTN product line is suitable for nuclear applications. This has butt-weld ends with bolted or pressure seal bonnet. The body can be forged or welded and the disc is made of stainless steel. It has a temperature range of -29 to 365 degrees Celsius.
The Hera product line can come with a wafer type single piece or two-piece cast iron body with PN pressure rating ranging from 10 to 150. Its temperature range is from -10 to 180 degrees Celsius.
TVM is a Level 1 B-BBEE Company with an ISO 9001:2008 certification. TWM is an industrial valve distributor in Cape Town, South Africa. It has partnered with LVSA, ROMOTAS, and PETREL. TVM offers engineering pipes, valves, and fittings. The main markets this company serves include mining, power generation, petrochemical, pulp & paper, sugar, iron & steel as well as food & beverages.
TVM knife gate valves come in ANSI Class 150 pressure rating. These valves can have sizes ranging from 2 inches to 36 inches and can withstand temperatures less than 100 degrees Celsius. Seats can be rubber, PTFE, stainless steel or carbide alloy. Valves carried by TVM can be used in wastewater, water, pulp, slurry and powder applications.
Butterfly valves can be used as a shut/off or throttling valve. It is compact, lightweight and takes little space. This kind of valve is suitable when the application requires a shutoff valve with a bubble-tight seal but placed in a tight space.
Butterfly valves can be classified according to the orientation of the butterfly valve seat. These can be concentric, double eccentric and triple eccentric. Butterfly valves are often used in pharmaceutical, chemical, and food industries.
LVSA is a butterfly valve supplier in South Africa. It provides industrial valves to several global brands. The market sectors LVSA valves are involved in include petrochemical, pulp & paper, iron & steel, power generation, mining, sugar, oil & gas and food & beverage industries.
LVSA supplies Neway API 609 cryogenic triple offset butterfly valve that can operate in LPG and LNG services below -100 degrees Celsius. This valve can have 72 inches in diameter and is bidirectional. It can have gray cast iron, ductile cast iron, cast steel, and stainless steel valve bodies. The sealing material can be made of EPDM, NBR, PTFE, and VITON.
Ball valves are one of the commonly used valves in industrial applications. These are quarter-turn valves that are often used to isolate or shutoff media.
Ball valves can either be trunnion-mounted or floating, based on the ball disc design. Ball valves can be also be classified depending on body style. These can be made of a single body, split body or top entry.
MSV carries a wide array of industrial valves including ball valves, butterfly valves, stainless steel check valves, needle valves, level control valves, and strainers. The company also carries branded industrial valves such as Checkrite, TaylowShaw, Clayton, Saunders, Leveldex, Vosa and Vent-o-Mat.

The seats can be made of PTFE with graphite packing. These valves can have sizes that range from 8mm to 200mm and pressure ratings ranging from Class 150 to Class 300.
Pressure relief valves are sometimes known as safety relief valves. These valves are designed to open at a preset pressure level and relieve the valve of excess pressure. This valve also allows for the pressure level to return to normal. There are two kinds of pressure relief valves. These are direct-acting deadweight pressure relief valves and direct-acting spring valves.
Industrial Valve and Engineering Supplies is a supplier of different kinds of industrial valves as well as strainers and steam traps. The company offers seven kinds of pressure relief valves. The valve features stainless steel ball with PTFE trims. The hydrostatic test pressure can reach 42 bar for the shell and 23 bar for the seats. These valves can withstand temperature that ranges from 0 to 100 degrees Celsius. All valves are made in South Africa.
Non-return valves only allow the media to flow in one direction. This kind of valve is installed in the pipe where conditions may cause reversed flow due to changes in pressure.
There are many different kinds of nonreturn valves. Some of these are spring-loaded type, swing type, and the clapper type. Nonreturn valves are often associated with backflow prevention in water systems.
