Butterfly Valves (GD-6)

Our butterfly valves are made with centering gauges according to there pressure range. Due to the thickness of the ring material we can bring in stop bars or other optional sealing elements. Butterfly valves are usually clamped between flanges.

GD-6

Depending on your application (temperature, element, pressure), we manufacture this valve from any material available on the market. Customized solutions regarding size, operation or element are possible upon request.
