The Metro Hydraulic Six-Port Double Selector Valve is a compact, heavy-duty hydraulic selector valve designed to direct hydraulic fluid between two separate circuits. This 6-port, 2-position valve allows an operator to control two double-acting cylinders with one 4-way control valve, or four single-acting cylinders using two 3-way control valves. Its open-crossover spool design helps provide smooth circuit selection as one outlet pair closes and the other begins to open. Selecting between two hydraulic circuits Operating two double-acting cylinders with one 4-way valve Operating multiple single-acting cylinders Adding auxiliary hydraulic functions to mobile or industrial equipment Diverting flow for attachments, implements, lift systems, and custom hydraulic circuits.
