Product Introduction
FUJI H11352 – V12 Working Head Solenoid Valve
Overview
The FUJI H11352 is a pneumatically actuated solenoid valve specifically designed for the V12 working head used in FUJI NXT and NXT II/III surface mount technology (SMT) platforms. It plays a critical role in controlling the flow of compressed air that drives various head functions such as nozzle pick-up, release, and Z-axis movement.
This compact and highly responsive valve is integrated within the V12 head assembly, contributing to high-speed and precise component placement operations.

FAQ Guide – FUJI H11352 V12 Working Head Solenoid Valve
1. What is FUJI H11352?
Answer:
The FUJI H11352 is a pneumatic solenoid valve installed inside the V12 working head of FUJI NXT/NXT II/NXT III placement machines. It controls the flow of compressed air to various internal actuators within the head, enabling precise control of nozzle movements such as suction, release, and Z-axis motion.
2. What does this solenoid valve do?
Answer:
It electrically switches air on/off to control pneumatic functions inside the V12 head, such as:
Nozzle vacuum control (suction/release)
Z-axis actuation (up/down movement of nozzle shaft)
Internal cylinder movement for mechanical positioning or switching
Its fast switching speed ensures reliable and repeatable high-speed placement.
3. Where is it located?
Answer:
The H11352 valve is mounted inside the V12 head assembly, usually near the pneumatic control block. It connects to both electrical signal cables and air supply tubing.
4. What are the symptoms of a faulty H11352 valve?
Answer:
Nozzle cannot pick up or release components
Air leakage sound from inside the head
Slow or no nozzle movement on Z-axis
Error messages related to suction failure or head malfunction
Irregular air response or weak vacuum pressure
5. How is it maintained or replaced?
Answer:
Inspect the valve during regular head maintenance cycles
Check for air leaks, loose fittings, or delayed actuation
Replace the valve if it shows signs of clogging, slow response, or electrical failure
Use ESD-safe tools and clean, dry compressed air
After replacement, test nozzle motion and suction
6. What is the air pressure requirement?
Answer:
The solenoid valve typically operates under 0.45 MPa to 0.60 MPa clean, dry compressed air. Ensure regulated supply to prevent valve failure or head malfunction.
7. Can it be replaced individually?
Answer:
Yes, the H11352 can be replaced independently without removing the full head.
Ensure you:
Disconnect the signal cable and air lines
Unscrew or release the valve from its mounting bracket
Reinstall using original FUJI-compatible parts and torque specs
