Explosion proof type 4way solenoid valve, YT-700D series outputs pressure to valves or changes output port direction. - Explosion proof type (ExdIICT6) solenoid valve. - Replacement of coil is easy due to AC and DC applied in same enclosure. - Manual switch enables user to test the operation when the power source is cutoff. - Connecting wires are easy because connection port can be rotated (265°). - Valve body is air pressure operating type, so the operation is very smooth with high durability. - Can be directly attached on actuator, because of NAMUR type design.
