NAMUR solenoid valves
Valves
NAMUR solenoid valves are used as pilot valves mounted directly onto process valve actuators (rotary actuators, diaphragm actuators) per the NAMUR standard. The DR NAMUR adapter plates provide 5/2-way throttling function (both sides) and 3/2-way versions with throttle on supply air (FO), exhaust air (FS) or both sides (FSFO) of the pressurised side. The 6 mm spacer plate (DR NAMUR DIS6) enables undercutting in confined installation situations on the process valve.
| Item | Switching function | Throttle function |
|---|---|---|
| DR NAMUR | 5/2-way | Both sides |
| DR NAMUR FO | 3/2-way | Supply air of pressurised side |
| DR NAMUR FS | 3/2-way | Exhaust air of pressurised side |
| DR NAMUR FSFO | 3/2-way | Supply and exhaust of pressurised side |
| DR NAMUR DIS6 | Spacer plate | 6 mm standoff |
Typical applications: Pilot control of ball valve and butterfly valve actuators per NAMUR standard in process plants; control of pneumatic rotary actuators in the oil and gas industry; regulation of opening and closing speed of process valves via integrated throttles; installation in Ex zones via upstream NAMUR amplifier.
