Mining and Minerals Processing is an area where critical valve failures can create expensive shut-downs. At Valvtechnologies we understand the importance of reliability and more importantly ZERO LEAKAGE. Valve leakage inside a slurry line will soon lead to dewatering of the slurry and expensive retrofit work, with extensive operational down-time.  Understanding the design and potential problems in the client's process is the way we understand their unique needs ... and we plan and respond. Our expertise in solving valve problems is directly related to our list of satisfied customers ... or what we
	prefer to call our business partners! We care about being in-country to assist, rather than saying "ship the valve back to Houston". Contact us for a solution to your problems in these difficult areas of valve applications.
	We have severe service valves that operate in process conditions that push the limits of engineering capabilities. From the Slurry Pipelines in China and South America to the Nickel Processing Plants of Western Australia and Asia, Valvtechnologies is there and we have the solutions.
ABRASOCHECK™ High Pressure Slurry Check Valves ASME 900-1500 The Valvtechnologies ABRASOCHECK™ Slurry Check Valve is an upgrade of a product that has been used successfully in service for more than 30 years at the Savage River Pumping Plant in Australia. Valvtechnologies has re-engineered and improved the design of this product to be in-line with our own technology for materials, coatings and manufacturing improvements. The combination of the Valvtechnologies ABRASOCHECK™ Slurry Check Valve and the Valvtechnologies ABRASOTECH™ Slurry Ball Valve provides zero leakage isolation for maintenance of positive displacement pumps. ABRASOTECH™ Slurry Ball Valves ASME 150-2500 The Valvtechnologies ABRASOTECH™ valve is the result of 20 years of experience in providing reliable valves for the transportation of slurries in cross country pipelines. With an installed base of over 3,000 slurry service valves throughout the world, Valvtechnologies is the established leader in these applications. The ABRASOTECH™ valve is offered in carbon and stainless steel materials. The valves internals can be protected against erosion and corrosion with the use of RAM© coatings as well as the use of metallic or urethane liners. Typical applications for this valve are as follows: Main-line Pump Isolation Valves where zero leakage is required to isolate operating from non-operating pumps. Station Isolation Valves where the pipeline needs zero leakage to isolate long portions of piping and pressure reducing (choke) stations. Choke Loop Diverter Valves where slurry is led into choke loops for pressure reduction. Rupture Disc Isolation Valves where zero leakage isolation is needed to provide isolation and replacement of blown rupture discs.
