SMC ITV1050-31F1BN3-X365 — ITV1000 Series Electro-Pneumatic Regulator, 0.005-0.9MPa, G1/8, 24VDC
2026-06-08The SMC ITV1050-31F1BN3-X365 is an electro-pneumatic regulator from the ITV1000 series that provides stepless, proportional control of output pressure in response to an electrical input signal. This model features a set pressure range of 0.005–0.9 MPa with a maximum supply pressure of 1.0 MPa, powered by 24 V DC and controlled via a 0–10 V DC voltage input signal. It provides a 1–5 V DC analog monitor output, with G 1/8″ threaded ports, a flat mounting bracket, no cable connector (user-supplied), and a bar pressure display unit. The enclosure is IP65 equivalent, and the -X365 suffix denotes a special-order variant. This regulator is ideal for precision pneumatic pressure control in tensioning systems, pneumatic balancing hoists, servo-pneumatic positioning, and leak testing.

Key Features and Benefits
High-Precision Proportional Control: ±1% F.S.
The ITV1050 delivers stepless, proportional output pressure control via a 0–10 V DC voltage signal, achieving linearity of ≤ ±1% F.S., hysteresis ≤ 0.5% F.S., and repeatability of ±0.5% F.S. Sensitivity reaches 0.2% F.S. — at a 100 kPa set point, pressure changes as small as 0.2 kPa can be resolved, meeting demanding precision control requirements.
Compact and Lightweight
The ITV1000 series features a compact footprint and lightweight construction, enabling installation in space-constrained equipment. The flat bracket mounting design integrates easily into automated machinery, test benches, and robotic end-of-arm tooling.
IP65 Equivalent Enclosure
With IP65 equivalent protection against dust ingress and water jets, the ITV1050 operates reliably in harsh industrial environments without additional protective covers. Suitable for washdown areas and dusty factory floors alike.
Built-In LED Digital Display
A bright, easy-to-read LED display shows the current output pressure in bar in real time, simplifying on-site commissioning, troubleshooting, and status monitoring without external instrumentation.
1–5 V DC Analog Monitor Output
The 1–5 V DC analog output can be fed into a PLC or supervisory system for closed-loop pressure control and data logging, enabling a complete pneumatic servo control architecture.
Low-Power 24 V DC Operation
Operating on standard 24 V DC with power consumption of ≤ 4 W (typically 0.12 A), the ITV1050 connects directly to industrial control cabinet DC power rails, minimising energy costs and thermal load.

FAQ
Q: What does the -X365 suffix mean, and how does it differ from the standard model?
The -X365 suffix denotes an SMC special-order variant. This means the unit has been manufactured with a custom modification relative to the standard ITV1050-31F1BN3 — this could involve a specific calibration range, special seal material, custom factory preset, or other bespoke engineering change. The exact nature of the -X365 modification must be confirmed with SMC. Base specifications (pressure range, signal type, port size, etc.) remain consistent with the standard model.
Q: Can this regulator be controlled with a 4–20 mA current loop signal?
No. This model is configured for voltage input (0–10 V DC) and cannot accept a 4–20 mA current signal directly. For current loop control, select the ITV1050-01F1BN3 (4–20 mA input) or ITV1050-012BL3 (current input with cable connector).
Q: What does IP65 equivalent protection actually mean for this regulator?
IP65 equivalent means the regulator is fully dust-tight (no ingress of dust particles) and protected against low-pressure water jets (6.3 mm nozzle) from any direction. It is suitable for dusty factory environments and areas subject to washdown spray, but it is not rated for continuous submersion in water.
Q: How can I verify that the output pressure is correct?
There are two methods: 1) read the LED display directly on the regulator body, which shows the current output pressure in bar; 2) read the 1–5 V DC monitor output via a PLC — the output voltage is linearly proportional to the set pressure (0–0.9 MPa = 1–5 V), allowing remote monitoring and verification.
