1276955
pulse valve VZWE-E-M22C-M-G2-500-H
The Festo part number 1276955 is an electrically actuated diaphragm valve featuring a corner design, soft sealing principle, and a 50 mm nominal size with G2 process valve connections on both ports. This piloted 2/2 closed, monostable industrial component operates with non-reversible flow direction, a differential pressure of 0.35 bar, and a medium pressure range of 0.35 to 8 bar using compressed air meeting ISO8573-1:2010 [7:4:4] standards. It delivers a flow rate Kv of 78 m3/h, a switching time on of 30 ms or less, mechanical spring reset, and functions within an ambient temperature range of -20 to 60 °C without lubricated operation.

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading.
