Explosion-proof solenoid operated valve with a terminal box which have a special structure that essentially internally isolates ignition sources, such as those at electrical connections, so that if explosive gases enter from the outside and ignite and explode inside, they will not adversely affect the outside.
Compact directional control valves using a rotary spool available in two models, one dedicated to manual operation and the other with a dog for cam operation (manual operation also possible). The structure has a high level of pressure balance, which suppresses the variation in the force required to operate the handle according to the pressure change.
