Brand: Festo

Piston actuator DFPK-46-17-V4

The Festo 8083959 is an industrial component featuring a valve actuator size of 46 and a 17 mm stroke with an any mounting position and a mechanical indicator for position sensing. Operating with a spring-loaded normally closed (NC) control function, this unit requires compressed air matching ISO 8573-1:2010 [7:4:4] within an operating pressure range of 0.5 MPa to 1 MPa (5 bar to 10 bar, 72.5 psi to 145 psi). It carries IP65, IP67, and IP69K degrees of protection, ATEX and UKCA markings for explosive zones 1, 2, 21, and 22, and VDMA24364 Zone III LABS conformity for ambient temperatures between 0 °C and 60 °C.

Why no listed price?

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.
