Industrial equipment supplier BMG has presented its range of industrial slurry valves, which has been designed to cope efficiently in harsh conditions. This range includes robust butterfly and knife gate valves, as well as diaphragm and pinch valves.

“These industrial slurry valves – which meet stringent quality and safety specifications – are highly efficient for the control and isolation of abrasive slurries in many industries, including power generation, chemicals and petrochemicals, cement handling, water treatment, mining, quarrying, and pulp and paper,” highlights BMG fluid technology sales manager Susan Victor.

“Failure of a valve and subsequent leaking of corrosive media can have devastating effects on the safety of personnel and equipment, leading to premature system failure and costly downtime . . . It is critical that the correct valve is selected for every application, for maximum safety, ongoing operation of the plant and minimum unscheduled maintenance,” she adds.

Victor also notes that BMG has a highly skilled team which has a sound understanding of the processes where valves are installed and supports every component with a reliable solutions service, to ensure optimum safety, efficiency and the extended life of each system.

The choice of the correct industrial slurry valve is based on factors that include the size and shape of particles, pressure, temperature and chemical content.

BMG highlights that polyurethane-lined knife gate valves are available in standard sizes between DN 50 and DN 600, with manual, pneumatic and electric actuation. These specific valves have a wafer pattern and are manufactured from cast and ductile iron, with stainless steel discs, and are said to withstand operating temperatures of between -20°C and 80°C as standard, with higher temperature resistances available on request.

In addition, polyurethane-lined, abrasion-resistant butterfly valves – in a wafer pattern or with a lugged design – are used for on/off control of abrasive slurries. BMG notes that the butterfly valves are available in standard sizes between DN 50 and DN 400.

Locally manufactured AFS/BMG diaphragm valves, between DN 50 and DN 350, with manual or pneumatic actuation are designed for abrasive slurry applications with a body pressure of PN 16-40 and withstanding temperatures between -10°C and 80°C.

“Long-lasting rubber and jumbo rubber linings are suited for full-bore diaphragm valves with a high flow capacity and an efficient sealing capacity, which shuts off any flow and prevents leakage. Full bore diaphragm valves also have a low pressure drop because there is almost nothing obstructing the flow of the fluid when the valve is fully opened. This creates little resistance to flow, which makes these valves suitable for fluids with abrasive particles,” comments Victor.

She adds that the BMG InterApp industrial valves are said to withstand operation in high temperature applications up to 200°C. This product range is designed for use in industries such as water treatment, chemical processing and the food and beverage sector. These valves are known for their durability, dependability and performance, making them a popular choice among engineers and industry professionals.

“BMG’s extensive range of components for fluid technology systems and general industrial applications encompasses power packs, lube units, manifolds, valves, hydraulic hoses and fittings, accumulators, filtration, cylinders, heat exchangers, pneumatics, hydraulic motors and hydraulic plumbing, as well as pumps and reservoir accessories. “BMG also offers a total process and lubrication management solution, to meet exact market requirements,” Victor concludes.
