Pneumatic Butterfly Valve DN32 (1-1/4 inch) Lug Cast Iron Stainless Steel NBR Spring Closing
This butterfly valve is pneumatically actuated, featuring a DN 32 bore size and a lug type connection for secure installation in piping systems. It is suitable for medium temperatures from 5 to 85°C (41 to 185°F), with a maximum media pressure of 12 bar (174 psi).
The actuator operates within a pneumatic input range of 3 - 8 bar (43–116 psi), delivering a constant torque of 20.9 Nm at 6 bar (15 lb-ft @ 87 psi). The valve body is made of durable cast iron with a stainless steel disc and an NBR seal, making it suitable for liquid and gas applications.
The actuator features a robust, single-acting rack-and-pinion mechanism with a 35-micron hard-anodized aluminum body. It is compatible with ISO 5211 F05/F07 valves and includes BSPP air ports for air supply and return. Additionally, it features a Namur 1/4 inch interface for solenoid valves and an 80 x 30 mm interface for VDI/VDE 3845 limit switch boxes. Comes unassembled, including butterfly valve (BFLL-32-12-BBB), actuator (V3JM2/PR04A), and mounting accessories.
