The Dual Valves Team has more than 40 years experience in technical and valve engineering in the slurry industry. We ensure our products are designed to suit customer specifications and requirements.

Based in Apex Industrial, Benoni, South Africa, we pride ourselves in being a local manufacturer of our entire range of products.

We manufacture a comprehensive range of Gate Valves, Pinch Valves, Ball Check Valves and many more.

With a strong team of determined and hard working engineers lead by Stephen Van Rensburg, we have successfully tackled some of the largest valve projects and have shipped our extensive range across the world.

WE HAVE BEEN ENGINEERING FOR OVER 40 YEARS.

With over 47 Products in our range, we have continued to engineer these products to increase longevity and ease of maintenance in situ, however this has not stopped us from finding new and innovative ways to increase the quality of our products.

Dual has been in the valve industry for over 40 years. In this time we have made significant progress in the manufacturing of valves, as well as finding the better solutions with materials that increase the wear life of our valves. All products are manufactured to ISO 9001:2015 and tested to ISO 5028 standards.

The company was started by Gerry Van Rensburg and Stephen Van Rensburg, his son.  Stephen is driven to always find the best solution to a mining or pipeline project.

Dual started with the DFV Valve which today still stands as our flagship model, adding to that, Dual has engineered and perfected many more products from Gate valves to Diaphragm Valves.

We manufacture in-house, which gives us the great flexibility to customise our valves to suit client requirements.

LATEST PROJECTS

1600NB DRDSV Valves

These 1600NB valves are electrically actuated using an electric actuator. Rated to 10 bar and fully rubber lined interior they are one of the biggest projects the Dual Valves team has taken on and completed.

750NB DFV Valves

These valves have a custom designed and fabricated steel ball insert to ensure the pressure of the valve over the 750NB interior is handled with ease. Shipped to the USA and with spares to ensure easy maintenance and longevity.

600NB DSPV Valves

The 600NB single pinch valves are the largest of their kind for Dual and around the world. The single pinch mechanism allows for better control and less moving parts, thus making this valve easy to operate and maintain in situ.

How is Dual preparing for POPI?

Dual is undertaking a comprehensive POPI project in South Africa, to enhance its already established internal controls to comply with POPI. Dual Valves’ POPI project involves a detailed assessment, remediation and validation of business processes, operational, IT (systems and applications), third party relationships and documentation to address any new and/or additional requirements under POPI.

How is Dual addressing POPI information security requirements?

We have an Information Security Policy in place, applicable to all information systems and applications used across the Company. We have policies and procedures in place for administrative, technical, and physical safeguards designed to appropriately protect the security, confidentiality, and integrity of Personal Information consistent with POPI.

The following measures were already in place prior to the coming into effect of POPI:

  • Internal policies for the secure handling of information;
  • Encryption tools and software to mitigate the unsecure sending of personal information outside our organisation;
  • Appropriate security systems in place to prevent unauthorized access and to combat malware, phishing and ransomware attacks;
  • Security measures in place where personal information is stored;

Where we contract third party services providers who may have access to your Personal Information on our behalf, we have an obligation to only appoint providers who can provide sufficient guarantees that the requirements of POPI, or other applicable data privacy laws, will be met, and the rights of data subjects, protected.

Is any Personal Information shared with Dual in South Africa transferred outside South Africa?

In certain circumstances, yes. There may be service providers that we engage that are located in countries outside of South Africa.

We may allow access to your Personal Information to parties outside South Africa. However, we have safeguards in place to protect any such data and require third parties receiving Personal Information and other confidential information, to agree to use and protect data consistent with applicable data privacy laws, including but not limited to POPI and The General Data Protection Regulation (“GDPR”).

Do we need to update any agreement in place with Dual for POPI compliance?
