Butterfly Valves

Bosch Rexroth Africa’s butterfly valves are quarter-turn valves that use a rotating disc to regulate, permit, or block fluid flow within a pipeline. Butterfly valves are distinguished by their compact design, quick quarter-turn operation, and cost-effective flow control. They are typically constructed from materials such as stainless steel, ductile iron, PVC, or high-performance alloys to suit various pressure, temperature, and chemical environments.

Types of butterfly valves from Bosch Rexroth Africa

Stainless Steel Butterfly Valves: Working temperature from 0° to 150 °C and a working pressure of PN 6.

Lug Type Butterfly Valves: The shaft comes in 2 pieces which increases ease of disc maintenance and allows a high kV due to a central section of the disk being thinner than a valve with a single shaft.

Wafer Type Butterfly Valves: The valve disc circumference has a lapped surface, which provides better tightness and less wear of the liner. Lower friction reduces torque requirements.

Metal-Metal Type Butterfly Valves: Constructed with high-quality materials, like nickel-plated steel, spheroidal cast iron and aluminium paint.

PVC Butterfly Valves: Ideal for use with double acting actuators and, on the standard version, the body is constructed from reinforced polypropylene fibreglass, PVC-C butterfly and EPDM seal.
