FAQs
The valve uses a G1-1/2 port size and Rc1/8 gauge port, supporting common pneumatic fittings and standard plug-in accessories such as M/P15737 and M/P19063. It also offers mounting compatibility via optional wall brackets (18-001-979), enabling straightforward retrofits and OEM integrations in existing lines.
Key specs include a operating pressure range of 3 to 10 bar (44 to 145 psi), flow capacity of 147 dm3/sec (312 scfm), and a 3/2 valve configuration with solenoid pilot and spring return actuation. The unit has an aluminium body, nitrile elastomer seals, and IP65 protection with sealed plug for harsh environments.
Yes. The design supports compliance with the European Machineries Directive and PUWER, helping start-up sequences meet safety and equipment-use regulations. The IP65 rating provides enclosure protection, and the sealed plug option simplifies installation in challenging environments without compromising safety.
Common applications include machine start-up sequences in packaging, automation, and manufacturing lines where controlled ramp of downstream pressure prevents shock loads. It is especially beneficial in environments with dusty or damp conditions, benefiting operations that require reliable venting and high forward flow without spikes.
With an aluminium body and nitrile elastomer seals, the valve combines durability with chemical compatibility in compressed air systems. The IP65 rating and robust materials reduce maintenance frequency, while the plug-and-play accessories ease servicing. This translates to lower total cost of ownership and longer mean time between failures in demanding plants.
