Waircom Series WB Complementary valve

Block valves series “WB” are produced in the 2/2 – G1/8″, G1/4″ and G1/2″ monostable pneumatic functions in both the uni- and bi-directional versions. The working of the block valve consists in avoiding unexpected depressurisation of the cylinder’s chamber due to lack of compressed air at the piloting port. For a correct functioning of the block valves we suggest to mount them directly on the cylinder.
