Pneumatic Butterfly Valve DN100 (4 inch) Wafer Cast Iron Stainless Steel EPDM Spring Opening
This butterfly valve is pneumatically actuated, featuring a DN 100 bore size and a wafer type connection for secure installation in piping systems. It is suitable for medium temperatures from -10 to 110°C (14 to 230°F), with a maximum media pressure of 16 bar (232 psi).
The actuator operates within a pneumatic input range of 3 - 8 bar (43–116 psi), delivering a constant torque of 55.9 Nm at 6 bar (37 lb-ft @ 87 psi). The valve body is made of durable cast iron with a stainless steel disc and an EPDM seal, making it suitable for liquid and gas applications. This model is also suitable for drinking water, holding DVGW approval.
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 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 (BFLW-100-16-BBA), actuator (V3JME/PR06B), and mounting accessories.
