Abstract

To provide a four-circuit protection valve, reduced in number of parts by forming a valve body as a single body structure, and keeping high strength. This four-circuit protection valve 1 includes the valve body 3. The valve body 3 is formed by a single body shaped to form a first body part 9 and a second body part 11 extending in a first axial direction 5 and in a second axial direction 7 being bent at the bent part 13 as the whole. An opening 54 for a check valve, which is provided for disposing a first check valve part 51 and a second check valve part 53 is formed in such a position as to be accessed from the outer walls 87, 88 of the bent part 13 not through another member.
