- Proven Reliability: KITZ SCT valves are widely specified in IGS (Integrated Gas Systems) for semiconductor fabs globally
- Traceability: Full material certification and test documentation available
Typical Applications
- Semiconductor process gas distribution (IGS / gas cabinet systems)
- Pharmaceutical and biotech process lines (CIP/SIP compatible)
- Chemical dosing and corrosive fluid control
- High-purity gas and liquid handling systems
- Laboratory and analytical instrument gas supply
- Automated process control panels and skids
System Compatibility
- Pneumatic Supply: Typically 4–7 bar (60–100 psi) instrument air or nitrogen
- Control Signal: Compatible with solenoid valve pilot (3/2 or 5/2 way) — specify fail-open or fail-closed
- Tube Fitting: BGC#A compression fitting — compatible with 6.35 mm (¼”) OD tubing
- PLC / DCS Integration: Actuator accepts standard 24 VDC or 110/220 VAC solenoid signals via pilot valve
- Position Feedback: Optional limit switch / NAMUR sensor bracket available
Selection Guide
Use the following criteria to confirm this valve or select the correct replacement:
- 1. Bore & Flow: Confirm 6.35 mm bore and required Cv/Kv for your flow rate
- 2. Body Material: 316L SS specified — verify media compatibility (acids, solvents, gases)
- 3. Actuation: Double-acting vs. spring-return — confirm fail-safe position (FA = Fail-Action; specify FO or FC)
- 4. End Connection: BGC#A compression fitting for 6.35 mm OD tube — confirm tubing OD and material
- 5. Pressure & Temperature: Verify rated WOG and temperature range against process conditions
- 6. Certifications: Confirm CE, SEMI, or other required certifications for your industry

Replacement & Compatibility FAQ
Q: Is P11104128 the same as TD4CB-GC-1003-FA-SEP-316LE?
A: Yes — P11104128 is the KITZ SCT internal part number; TD4CB-GC-1003-FA-SEP-316LE is the full model/configuration string. Both refer to the same valve assembly.
Q: What does “SEP” mean in the model number?
A: SEP indicates the body material is 316L Stainless Steel (Stainless Electropolished/Passivated grade per KITZ SCT nomenclature).
Q: Can I replace this valve with a Swagelok equivalent?
A: Swagelok offers comparable ¼” SS pneumatic ball valves, but actuator interface, Cv, and fitting dimensions must be verified. Contact us for a compatibility review.
Q: What is the “FA” designation in the model?
A: FA = Fail-Action — specifies the actuator’s fail-safe behavior. Confirm whether your application requires Fail-Open (FO) or Fail-Closed (FC) and verify the spring configuration.
Q: Do you supply the solenoid pilot valve separately?
A: Yes — compatible solenoid pilot valves (NAMUR or inline) are available. Contact us with your voltage and port size requirements.
