Pneumatic Butterfly Valve
Pneumatic butterfly valves provide fast, reliable on/off control for air, gases, water and liquids. With coated aluminum, ductile iron or stainless bodies, they deliver tight shutoff and durable performance across millions of cycles. Configurable accessories available.
Description
Our pneumatic butterfly valves provide reliable on/off flow control for air, gases, water and compatible liquids. The disc design allows quick open/close cycling while sealing tightly when closed. Available in lug or wafer styles, these valves feature corrosion-resistant coated aluminum, ductile iron or stainless steel bodies.
The floating seat configuration enables effective shutoff and adjustment of wear over time. High-strength shafts and heavy-duty bearings provide durable performance with millions of operation cycles. Optional accessories include solenoid valves, limit switches and positioners. With sizes ranging from 2-48 inches, our butterfly valves suit various commercial and industrial piping systems.
Contact our application engineers to select the optimal materials, seals and accessories based on your operating conditions.
