It has a 40 mm nominal diameter (1 1/4 inch) and operates at a maximum pressure of 10 bar. The valve features a PTFE diaphragm and an EPDM O-ring, with a flow coefficient (kv-value) of 759 l/min at Δp=1 bar. The overall length is 192 mm, with a lift height of 15 mm, and it weighs 1.965 kg. The valve includes an M8 thread for air connection and is compatible with rotating air fittings at 90° intervals for flexible installation.
