Festo
165081
On/off valve HEL-3/4-D-MIDI
The Festo 165081 is a directly controlled pneumatic industrial component featuring a 2/2-way, closed, monostable piston gate valve structural design with a soft sealing principle and mechanical spring reset method. It provides an adjustable exhaust air function, a non-reversible flow direction, and operates within a pressure range of 0.3 MPa to 1.6 MPa (3 bar to 16 bar) while handling a normal nominal flow rate of 3800 l/min at a medium temperature range of -10 °C to 60 °C. Rated for moderate corrosion stress with a CRC of 2 and VDMA24364-B1/B2-L LABS conformity, this unit utilizes compressed air as per ISO 8573-1:2010 [7:4:4] or inert gases with oil lubrication operation possible.

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.
