Disclosed is a balanced poppet-type electromagnetic valve (10) wherein a valve section (11) in the balanced poppet-type electromagnetic valve (10) includes a body (12), a poppet valve (41) housed in said body (12), and a valve-seat shaped body (17) which is mounted in said body (12). A second valve seat (19) a first valve seat (18) and a second valve seat (19) forms the valve-seat shaped body (17). One opening of the body (12) is sealed by the valve-seat shaped body (17). A first communication path (42c) and a second communication path (43c) are formed in a poppet value (41) to connect a first pressure chamber (S1) and a second pressure chamber (S2) partitioned within the body (12). The poppet valve (41) is maintained in an equilibrium state by the pressure of positive air. A seal member (45) which seals between the first pressure chamber (S1) and a supply port (13) is provided in the poppet valve (41). The seal member (45) is disposed between a valve (44) and a first end of the body (12). |
