BMG’s butterfly valves

2nd Quarter 2016 Hydraulic systems & components

BMG’s strategy to enhance its fluid technology services to meet growing market demand encompasses the introduction of new products featuring the latest developments in design technologies, materials and coatings.

The company’s expansion programme in the fluid technology sector also involves increasing stockholdings through more than 140 BMG branches and a wide distribution network in South Africa and across borders into Swaziland, Zambia, Botswana, Mozambique, Namibia and Tanzania.

“BMG boosts its fluid technology services with dependable technical support to ensure optimum safety, efficiency and extended service life of every system, even in corrosive environments. With broad technical capabilities, our team is able to solve problems in applications where conventional components have failed after short periods of service,” says fluid technology manager, Wayne Holton.

BMG’s fluid technology services also cover project engineering and consulting, cylinder design and manufacture, training, repair and testing, as well as onsite container services. The company’s extensive range of components for fluid technology systems and general industrial applications includes valves, hydraulic hoses and fittings, accumulators, cylinders, heat exchangers, hydraulic motors and hydraulic plumbing, as well as pumps and reservoir accessories. “Compact butterfly valves, with good flow characteristics and low maintenance requirements, are important components in BMG’s extensive range of valves for industrial flow control,” says Willie Lamprecht, national product manager, valves. “An advantage of using quarter turn butterfly valves rather than any other type of valve, is the simple, wafer shaped design, with fewer parts for easy repair and minimal maintenance.”

Although butterfly valves and ball valves are both quarter turn, the benefit of butterfly valves is when they are actuated pneumatically, they open and close very quickly. The rotational disc in butterfly valves is lighter than a ball and these valves require less structural support than a ball valve of the same diameter.

Unlike a ball valve, the disc of butterfly valves is always present in the passageway within the flow. This means a pressure drop is induced in the flow, regardless of the position of the valve. Ball valves should only be used for isolation, whereas butterfly valves can be safely used for isolation and control of flow.

BMG’s Desponia centric butterfly valves (DN 25 -1600) with an elastomer liner are designed for safe and reliable regulation of liquids and gases in diverse industries. This range has a maximum working pressure of 16 bar and an operating temperature range between -20 and 140°C according to the material.

Bianca centric butterfly valves (DN 32-900) with an on/off and control service, have a durable plastomer liner suitable for aggressive and corrosive fluids. These high performance valves have a 16 bar maximum working pressure and an operating temperature range between -20 and 200°C, depending on working conditions. Special ATEX valves in this range are suitable for use in explosive atmospheres.

Other valves available from BMG include seated, knife and wedge gate valves, as well as ball type check valves, thermoplastic, diaphragm, pinch and angle seat valves.

This range is suitable for reliable performance in diverse industries, including mining, refining, power generation, iron and steel, materials handling, food and beverage, pharmaceutical, paper and pulp, chemical, sugar and automotive.
