Mascot Control Valves Engineered to Perform
The use of water to sustain plant operation, or plant processes, is becoming more sophisticated as the mining and water Industries find new ways of working.
There is an increased need for creative and sophisticated solutions in control valve design to ensure smoother and more reliable processes with less valve maintenance.
That’s where MASCOT control valves excel in providing customers with design solutions, such as low flow, tight shutoff, anti-cavitation, broader range of material options and faster delivery times.
There are four key areas where the company are commonly seeing increased operations.
These include desalination, the use of reverse osmosis, the need for greater control within various mining processes, and the increased use of higher alloy/exotic materials due to the nature of chemical composition of raw waters.
Subsequently, more customers are looking to MASCOT for equipment with sophisticated and custom design trims.
The company has supported some of Australia’s most significant projects with the supply of complex control valve solutions, including the Cosmos Gold Mine (IGO), Racetrack / Paddington Refractory Gold Project (Norton Gold Field), desalination projects, OSMOFLO and Roy Hill projects.
MASCOT products are a regular feature in a range of heavy industries where harsh conditions demand heavy-duty control valves, choke valves, actuated valves, and associated equipment for both standard and severe service applications.
From mineral processing, oil and gas, LNG processing and regasification, to power generation, chemical refining, to high pressure acid leaching, cryogenic and anti-surge applications,
MASCOT’s industrial solutions are manufactured in Australia to the highest standards.
According to MASCOT Managing Director Paul de Man, the right control valve solutions play a significant role in mineral processing applications, particularly due to the many processes involved and type of minerals being extracted.
“Our extensive knowledge and experience in mineral processing, combined with a specialised range of rugged control valves allow MASCOT engineers to select the correct valve for the right end-user application,” said Paul.
“We’re focused on maximising end-user production and reducing overall plant operating costs.
We achieve this by designing control valves that provide the lowest MTBPM against our major competitors, and ensuring they are built to suit the toughest industrial environments.”
MASCOT in the Field
MASCOT recently partnered with an engineering consultant on IGO’s Cosmos Projectin Western Australia to deliver 15 x DN15 PN16 TAPERFLO trimmed control valves for NaEX, PAX and CuSO4 solution, and low-flow application.
Additionally, it supplied 18 control valves and 5 x DN20 PN16 TAPERFLO for reagent low-flow application, at Norton Gold Fields’ Paddington Gold Mine.
Paul commented these applications had typically utilised rudimentary control, achieved via standard basis ‘weir-type’ control valves.
“With sophistication came the need for greater control of the process, and greater control at significantly lower flow rates.
As we’re specialists in low-flow control applications, we were able to meet the requirements for each of the site processes involved,” he said.
The company also collaborated with an Original Equipment Manufacturer, on a large-scale desalination project which required the provision of a cost-effective control valve solution.
Given the bulk of the manufacturing costs were due to the exotic alloy materials typically used in desalination applications, MASCOT adopted an alternative approach by substituting the more expensive alloy/exotic materials.
“We came up with a solution that used standard 316 stainless steel as the base material and applied a proprietary coating internally & externally for all pressure containing components,” said Paul.
“This consisted of valve body and bonnet, and a Xylan-1424 protective coating for both internal and external areas of the valve, which negated the need for expensive materials, saving the customer money without any degradation to the operating life of the equipment supplied.”
Two other desalination projects where MASCOT has applied its technical expertise and quality product support include both seawater applications and a desalination plant at Roy Hill.
This involved supplying manually operated super duplex (5A) globe valves of various sizes ranging from 3” to 6” up to 600# pressure class for seawater and characterized super duplex (5A) anti-cavitation rotary ball valves (VFLOs) from 12” to 20” class 150#, working with saline water.
“The challenge in these applications involves a phenomenon referred to as ‘cavitation’,” said Paul.
“This shortens the operating life of the equipment, therefore disrupting plant operation, which can lead to costly downtime.
“Our proven technology is designed to solve the issues caused by cavitation, which is why we utilise both rotary and globe valve configurations.
In the projects above, standard valves just wouldn’t have cut it in their processes.
The size and complexity of our customer’s plant design required a more sophisticated valve solution, hence why we supplied valves with our signature anti-cavitation trim.”
As processes in the mining and water industries continue to evolve, and the greater push for desalination across industries increases, MASCOT are looking forward to supplying more innovative control valve solutions.
With a proven track record of expertly engineered equipment and customer- first solutions, MASCOT are pursuing similar projects all the time.
And you never know, if you glimpse that signature yellow out in the field, it could just be a MASCOT valve.
