Key Features
3700 l/min Nominal Flow
The documented standard nominal flow rate is 3700 l/min, standardized according to DIN 1343.
G1/2 Pneumatic Ports
The main pneumatic ports use G1/2 connections for integration into suitable compressed-air circuits.
2-8 Bar Operating Range
The documented operating pressure range is 2 to 8 bar for this MFH valve configuration.
Pilot-Actuated Design
The valve uses a pilot-actuated poppet-seat design with soft sealing and a mechanical spring return.
Separate Solenoid Coil
The operating voltage is determined by the compatible F solenoid coil, which is specified separately from the valve.
Applications
- Pneumatic directional control circuits
- Pneumatic cylinder and actuator control
- Automated assembly machinery
- Material handling equipment
- Packaging and processing machinery
- Production automation systems
- Compressed-air control installations
- General industrial pneumatic applications
