Product Overview
The Parker DX03-406-70 Pneumatic Spool Valve is a heavy-duty, directional control valve engineered for demanding automation and pneumatic machinery circuits. Manufactured by Parker Hannifin under the proven ISO 5599-1 valve platform, this size 3 (DX03) subbase-mounted valve utilizes a remote air pilot actuation mechanism with a mechanical spring return. It delivers high-flow directional air routing to large-bore pneumatic cylinders, rotary actuators, and heavy air-powered equipment without requiring an integral electric coil directly on the valve body.
Constructed with a rugged die-cast aluminium housing and Parker's wear-compensating ceramic or precision-lapped spool and sleeve architecture, the DX03-406-70 ensures exceptional dirt tolerance, long cycle life, and low friction under continuous operating conditions. Designed to mount onto standard ISO 5599-1 Size 3 subbases and manifolds, it features an external pilot port that enables remote pneumatic signaling from secondary pilot valves or centralized control enclosures. It is widely utilized across automotive manufacturing plants, heavy foundry operations, timber processing facilities, and high-speed industrial packaging lines.

How do I find the right part for my system?
Three options. Search by part number if you have the OEM code from Parker, Danfoss, Linde, Kawasaki, Kayaba or Grundfos — our search recognises both manufacturer codes and aftermarket cross-references. Browse by category if you know the component type (pumps, valves, cylinders, etc.). Or send a spec sheet to our engineering desk and we'll cross-reference against our 3,000+ SKU catalogue within one business day.
Can you help me size a pump or valve for my application?
Yes — sizing support is included with every order. Send us your operating pressure, flow rate, viscosity, drive speed and duty cycle, and our engineers will recommend a suitable component from our catalogue with full datasheets. We don't custom-build parts ourselves, but we can spec the right OEM component for almost any standard industrial application.
Can you cross-reference a discontinued part?
Yes — cross-referencing is one of the things we do most. Send us the original part number (even if the manufacturer has dropped it) and our engineering desk will identify a current equivalent or compatible alternative. Cross-reference lookups are free and typically come back within 4 business hours.
