SBP Butterfly Valves plastomer-lined for shut-off, flow control or throttling of corrosive and abrasive process media in either liquid or gaseous state.
	Main Features • Robust construction, maintenance-free • Bubble-tight shut-off throughout • the full pressure- and temperature range • Unique shaft sealing arrangement assures • maintenance-free operation at automated • processes and high operating pressures, • with optimized and reinforced liner shape • No need of additional flange gaskets due • to wide and chambered sealing surface • One-piece disc/shaft for hysteresis-free • flow control, with polished sealing surface • leading to low torque values • Handlever, gearbox or pneum. actuator	Technical Data • Nom.
