Purchasing and Supply expert Benjamin Zis highly recommends Plasson’s new valve based on his experience during his work at Salt Lake Mining Pty Ltd, Beta Hunt Mine until earlier this year.
The Beta Hunt Mine, located in Kambalda, WA, is a deposit with the scarce feature of hosting both nickel and gold resources in adjacent discrete mineralised zones. Salt Lake Mining used Plasson’s 2:1 fixed ratio valve to process the underground water and the Alpha decline at its Beta Hunt mine. RNC has a 100% interest in Salt Lake Mining Pty Ltd.
Q. How would you describe the site and water conditions of the Plasson 2:1 fixed ratio valve in use?
The valve was placed in a small cutty of the primary decline in moderately high traffic and wet environment; the water was super saline and at high head pressure.
Q. How did the installation process of the valve go? Did you notice any leaks?
The valve performed well and was as simple to install as a standard Plasson coupling. There have been no instances of the Plasson 2:1 fixed ratio valve leaking as yet.
Q. What makes the Plasson valve advantageous compared to other products?
The easier installation and the ability to fit the valve directly to the poly water line meant no metal was left exposed to the environment and there was no need to space the line of the walls to prevent contact rust with ground support or wall hooks. The lack of corrosion and zero impact from the sun makes it an ideal option for underground operations.
Q. Do you have confidence in the valve and would you recommend it to others?
I would recommend the valve as an absolute must-have addition to any Plasson installation; it is a simple and effective alternative to the industry standard valves that eliminates many of the common problems encountered.
Q. In general with all Plasson fittings you have used on site, would you recommend them?
With 10+ years in the mining industries, I have personally come to depend on the Plasson range for dewatering and poly fixtures. Their superior design, interchangeable parts and readily available supply network mean I can always rely on the brand.
Product Details
Plasson’s new lightweight fixed ratio pressure reducing valve is designed to reduce static “head” pressure, especially in underground mining water supply systems.
The pressure is reduced by a fixed ratio of either 3:1 or 2:1. The valve also protects pipework by reducing surge and water hammer.
Features
- Stable pressure control over the full flow and pressure range
- Corrosion-resistant plastic body and internal parts
- Enhanced flow design and diaphragm reduce the damage caused by abrasive solids (sand, stones) and increase service life
- Lightweight: for easy handling
- Assembled directly to PE pipe by built-in Plasson compression fittings
- Can be installed either vertically or horizontally
