Who it’s for: engineers focusing on energy efficiency and compact footprints. Why chosen: DC24V operation pairs with many control panels designed for lower power draw.
Caution: check compatibility with your power supply and ensure the voltage matches the control electronics to avoid underperformance.
NAMUR Specifications Internal Pilot-Operated Valve
Designed for precise control, this 2-position valve with internal pilot operation marks a reliable choice for sophisticated automation lines requiring tight actuator coordination. The DIN socket type supports straightforward integration into modular systems.
Who it’s for: systems needing precise, centralized pilot control with DIN socket compatibility. Why chosen: robust control with predictable actuation characteristics. Caution: ensure pilot pressure requirements align with your actuator specs to avoid mis-tiring or delayed response.
ASCO WT8551A001MS Aluminum Body Pilot Operated Valve
This aluminum-bodied 5-way Namur mount valve supports a 1/4″ pipe size and provides a higher level of durability for demanding pneumatic applications. The nitrile sealing offers reliable performance under typical industrial fluids and pressures.
Who it’s for: industrial environments requiring rugged housing and long-term wear resistance. Why chosen: 5-way configuration enables more complex valve control in a single unit. Caution: aluminum housing can be more sensitive to certain chemical exposures; validate compatibility with your media.
Buying Guide: Namur Mount Solenoid Valves
What to consider when selecting:
- Mounting standard: NAMUR mounts are designed for compact, modular layouts. Confirm the mount type on your actuator and control panel.
- Voltage and drive type: DC24V is common for automation, while AC variants exist. Ensure compatibility with your control electronics and power supply.
- Port size and flow: 1/4″ and 3/8″ ports cover a wide range of actuation needs. Choose based on required flow and pressure ranges.
- Materials and environment: aluminum housings offer durability; nitrile sealing and other elastomers influence chemical compatibility and temperature tolerance.
- Number of ports and positions: 4-way/5-way configurations enable more complex control schemes. Align with your actuator’s requirements.
- Direct vs pilot operation: direct-acting valves respond quickly but may have different load limits; pilot-operated variants excel in larger systems.

Frequently Asked Questions
- What is NAMUR mounting? NAMUR mounting refers to a standard interface for attaching sensors and valves to pneumatic actuators, enabling compact, modular assemblies.
- Do I need a 4-way or 5-way valve? 4-way valves control double-acting actuators; 5-way valves support additional pilot or exhaust lines for complex control.
- Is DC or AC better for Namur valves? DC is common in low-voltage control systems, while AC variants are used where higher power is available or required by the control system.
- What should I check before buying? Port size, operating pressure range, and compatibility with your actuator and control electronics are key factors.
- Can Namur valves operate with water or oil? Many NAMUR valves are designed for air or inert gas; check media compatibility in each product’s specs to ensure safe operation with intended fluids.
