product

• Seat supported ball valve with an integral downstream seat – extended wear life
• Traditional failure modes (slurry wear from passing and coating failure) eliminated
• Rhinoite® weld-applied carbide hard facing leads the industry for wear resistance – extended wear life
• Integral seat eliminates the traditional gap between the seat ring and the body pocket, which is a leak path
• Integral seat cannot move and will keep a continuous wiping action to maintain the sealing surfaces clean at all differential pressures
• The Rhinoite® process includes sealant which aids lapping/sealing and minimizes torque requirement

• Improved performance and reliability 
• Increased operational uptime, production runs and end-user revenue

Case Study: Outperforming the competition

Location: Russia
Product: Autoclave discharge block valve
Industry: Mining and minerals
Product: 1 Qty, 1/2” ANSI Class 300 AbrasoBlock® valve

Challenge: To achieve 500 cycles and 50 hours operation without failure of the valve, during an accelerated product trial

Solution: The valve test will take place during the test/elaboration of the autoclave POx- technology of the gold bearing sulphide concentrate into the pilot autoclave line. The purpose of the pilot plant is to test different coating technologies to find a solution for the inherent problems in other valve designs and coating technology during this difficult process.

The AbrasoBlock® integral seat design valve was installed in the pilot plant and trial commenced.

Result: The trial was completed with excellent results. The valve successfully achieved 75.5 hours and 970 strokes of operation. This by far outperforms all other manufacturers’ autoclave block valves trials. The end-user will proceed into commercial supply agreement for valves to be installed in their industrial autoclaves.
