Cover plates
Accessories for valves
Festo cover plates seal unused positions in valve terminals and valve blocks. The 38-article range covers five product groups: PRSB cover plates for ISO sub-base plates (G1/8, G1/4, G3/8), PALB cover plates (1/8, 1/4, 3/8 inch), CPE-PRSB for CPE valve terminals (sizes 10/14/18), VABB cover plates for VABE valve terminals (S4/S2/C8 series), and CDB cover plates for cassette valve blocks (G1/4, G1/2) plus MHAP cover plates for the MHA1 series (BP-3, sizes 1-4).
Cover plates serve two functions: pneumatic closure of free channel openings in the terminal block, and mechanical protection of the mounting face against contamination. For VABE terminals, WT (white, temperature-resistant) variants are available.

Typical applications: Blanking unoccupied positions in CPE and VABE valve terminals to maintain channel pressure, blank-off of ISO sub-base plate positions in valve blocks, protection of unused MHA1 positions against contamination, and preparing terminal platforms for future expansion.
