Namur mount solenoid valve with warranty

ASCO SCG551A001MS | 551 Series 5/2 Solenoid Valve 1/4" NPT, 24V DC, Spring Return, Namur Mount
ASCO SCG551A001MS 551 series 5/2 or 3/2 way solenoid valve — 1/4" NPT ports, Namur interface, spring return (monostable), 24 V DC, 3–10 bar. For piloting pneumatic actuators & cylinders.

Product Overview

The ASCO SCG551A001MS​ (commonly referenced as SCG551A001MS, Numatics/ASCO 551 Series) is a 4-way (5/2 or 3/2 convertible) solenoid pilot valve​ with a Namur direct-mounting interface​ for controlling single-acting or double-acting pneumatic actuators. It features 1/4" NPT ports (or G1/4" in metric regions — Suffix MS typically denotes Metric/G threads or special seal material; base 551A001 = 1/4" NPT), spring return (monostable / single solenoid), and is supplied for 24 V DC (8 W coil, Class F)​ operation. The valve is convertible between 5/2 (double-acting cylinder pilot) and 3/2 (single-acting cylinder / normally closed) by rotating the exhaust blanking plugs. Body is anodized aluminum; seals are NBR (Buna-N)​ standard. Suitable for piloting process valves, air cylinders, and clamping devices in general industrial automation.

Technical Specifications (Valve & Flow)

Parameter
Specification
Model / Order Code
SCG551A001MS​ (ASCO Numatics 551 Series — Monostable, Namur, 24 V DC)
Series

Function
5/2 Way (Double Solenoid convertible to 3/2 NC)​ — spool type
Actuation
Single Solenoid, Spring Return (Monostable)​ — de-energize → spool returns to home position

Key Features

  • Namur Direct-Mount Capable:​ Bolts directly onto the pilot port of a pneumatic actuator — eliminates tubing between valve and actuator for single solenoid 5/2 or 3/2 applications.
  • Convertible 5/2 ↔ 3/2:​ Rotate exhaust blanking plugs / re-arrange port labeling — one valve covers both double-acting (5/2) and single-acting spring-return (3/2 NC) pilots.
  • Spring Return (Monostable):​ Fails to safe position on loss of power / air — important for safety-related actuator fail-close/fail-open logic.
  • Manual Override with Lock:​ Allows bench-test and commissioning without energizing coil; lockable to prevent accidental operation.
  • Interchangeable with Competitors:​ Dimensionally compatible with Festo MN1H / SMC VQC / Norgren 8400 series Namur-mount spool valves in same envelope.

Typical Applications

  • Pneumatic Actuator Pilot:​ Single solenoid 5/2 pilot for double-acting process/quarter-turn valve actuators; 3/2 NC pilot for spring-return actuators.
  • Air Cylinder Directional Control:​ Small-bore cylinder control where Namur-mount simplifies panel layout.
  • Clamping / Fixture Air Circuits:​ Start/stop air to vacuum cups, toggle clamps, and grippers.
  • OEM Packaging / Converting Machinery:​ Compact pilot valve for integrated manifold or actuator-direct-mount.

551 Series typical option decode: 551 = Series | A = Single solenoid spring return, Namur mount, NPT ports | 001 = 24 V DC 8 W coil, NBR seals, DIN plug (no plug shipped) | MS = Often denotes Metric/G thread variant or special packaging — verify against ASCO cross-reference if G1/4 required. For double solenoid (no spring return / bistable) see 551B… ; for 110/230 V AC coil see -Axxx suffix variants. DIN 43650 connector with LED+spike suppression (e.g. ASCO 238714-006 or generic Hirschmann / Binder) ordered separately.
