Festo
The Festo part number 34877 is a screw-in industrial component featuring an unlockable check valve function with 1/8 NPT pneumatic connections 1 and 2. It operates at pressures from 0.03 MPa to 1 MPa (0.3 bar to 10 bar) and handles a normal nominal flow rate ranging from 0 l/min to 260 l/min using compressed air as per ISO 8573-1:2010 [7:4:4]. The unit functions within an ambient and medium temperature range of -20 °C to 80 °C, requires a pilot pressure of 2 bar to 10 bar (0.2 MPa to 1 MPa or 29 psi to 145 psi), and permits oil-lubricated operation which becomes mandatory for subsequent use.
