Festo
34433
Pneumatic valve VLX-2-3/8-MS
The Festo part number 34433 is a pneumatically actuated diaphragm valve featuring a soft sealing principle, an in-line installation design, and a G3/8 fitting connection with a 13 mm nominal width. Constructed with a brass housing and supporting any mounting position, this 2/2-way closed monostable valve operates with a non-reversible flow direction under a medium pressure range of 1 bar to 10 bar. It utilizes piloted control via compressed air matching ISO 8573-1:2010 [7:-:-] standards, paired with filtered compressed air requiring a 200 µm filter mesh, a pneumatic spring reset method, and a normal nominal flow rate of 3800 l/min.

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.
