3‑Port Solenoid Valve, Direct Operated Poppet Type, VKF300 Series Specifications
VKF300 Series body ported type external appearance
VKF300 Series base mounted type external appearance
Output port: Set-up a manifold enabling 360° (in 90° increments) rotation of 2 (A)
Manual override is available from the valve top surface and from the side surface, allowing manual operation unaffected by mounting space and piping direction

*1: Based on JIS B 8374-1981 dynamic performance test. (Coil temperature of 20°C, at rated voltage, with no surge voltage suppressor)
*When a DC solenoid and surge voltage suppressor is provided, there will be a 10 to 20‑msec delay in the OFF response time.
*2: Impact resistance: No malfunctions after testing using a drop-type impact tester under the following conditions: in the axial direction and at a right angle to the main valve and armature in both energized and non-energized states (once for each condition state). (Initial value)
Vibration resistance: No malfunctions occurred in a 1-sweep test between 45 and 2,000 Hz. The test was performed in both energized and non-energized states and in the axial direction and at right angles to the main valve and armature. (Initial value)
