WHO ARE WE?
Hydrocore™ (formally NGD Valves) is an engineering company trading its own designed & developed products since 1986. We manufacture our own range of isolating, safety and control valves and our own patented range of pipe connectors. Our products are truly unique designed for robustness, efficiency, ease of use and long term savings. With years of industry experience and expertise, we have become a reputable brand, and the preferred supplier of specialised valves in the mining industry.
- Albert Einstein
HOW ARE WE BETTER THEN THE REST?
Our design philosophy is to simplify the complex and create more durable, reliable and efficient products. All of our products are borne of this ideology. Our products are revolutionary in terms of their ease of installation and use, robustness, long term cost benefits and maintenance. The purist nature of our designs
create innovations not imitations. Our products are built from the ground up to deliver distinct advantages over rival products without compromising on performance, ease of use, or standards.
WE HAVE BEEN AROUND THE BLOCK AND BACK
Our products are by no means “new”. They have all been tried, tested, and have many times evolved over the past 30 years. Over 7000 valves have been sold so far. To date, our entire focus was supplying high pressure applications to the mining industry in southern Africa. Mainly SA, but as of recently Australia too. Below is a list of the dominant places where our valves have been commissioned.
GO WITH THE FLOW
The Hydrocore valve is the only globe valve that breaks away from the standard globe valve and works in an entirely different way. Instead of applying a force on a plug (disc) to regulate the flow, the Hydrocore valve uses a hydrostatically balanced shuttle to regulate the flow. Our hydraulically balanced valve, requires very low operating forces to actuate. Therefore, no gearbox is required to assist in the valve’s opening or closing. The absence of a gearbox to operate the valve eliminates the risk of malfunctioning and offers a far higher lifetime over traditional valves such as ball valves that rely on gearboxes to operate.
SIMPLICITY OF DESIGN
A complicated valve is a valve that invariably will have issues once the valve is commissioned. The simpler the design the better. This is the curse or blessing of K.I.S.S. (keep it simple stupid). Our valve is simple and reliable with a robust construction.
The more moving parts in any valve design the more prone the valve will be to constant maintenance and servicing. This is even more of a concern in a setting where conditions are not optimal for smooth valve functioning. The Hydrocore valve is simple to maintain and service compared with a standard globe valve.
LOWER RUNNING COSTS
Since 2010 we have been improving the design of our valve range in order to be more energy efficient. The cost of electricity in today’s economic climate has increased significantly in general, and skyrocketed for the mining industry in particular.
Our new HCA (angular) models have an enlarged, less obstructed opening which minimises the flow resistance. Our flow coefficient (Cv) is vastly superior to those of standard globe valves. The electrical cost savings of our valves is absolutely mind boggling. An illustration of these savings is shown on the following page.
If a valve keeps on breaking down and requires constant servicing and maintenance, then the valve is no more an asset. In fact, it is now an obstacle to the smooth
running of the entire operation. Inevitably, the valve gets replaced by another brand. The Hydrocore valve, if maintained on a regular basis, will be keep on functioning indefinitely.
