Supported Applications
The Dwyer Series SN NAMUR Mount Solenoid Valve is designed to mount directly to pneumatic valve actuators, reducing the need for tubing, fittings, or brackets. The series serves two primary actuator configurations: 3/2 solenoids are designed for spring return actuators, while 5/2 solenoids are designed for double acting actuators.
Service is limited to air only. Standard features include a manual override and BUNA (Nitrile) O-rings.
Operating Conditions & Performance
The Series SN operates within an ambient temperature range of 23 to 140°F (-5 to 60°C). Supply pressure requirements are specified as 22 to 116 psi (1.5 to 7.9 bar).
Electrical specifications include a DIN 43650 form A connection and an IP65 enclosure rating. The unit weighs 1.0 lb (.45 kg) and carries CE compliance.
Configuration Options
The series offers configurable power supplies to accommodate various control environments, including:
- 24 VAC
- 110 VAC
- 220 VAC
- 12 VDC
- 24 VDC
Air connections are provided via 1/4" female NPT ports. The mounting interface follows the NAMUR standard, with specific dimensions varying by valve way (3/2 or 5/2).
Key Product Differences
Variants within the Series SN differ primarily by action type and power supply voltage:
- Action Type: Models are available as either 3/2 (Spring return) or 5/2 (Double acting).
- Power Supply Codes: Model suffixes indicate the specific voltage configuration. For example, SN-3A and SN-5A denote 110 VAC; SN-3B and SN-5B denote 220 VAC; SN-3C and SN-5C denote 24 VAC; SN-3E and SN-5E denote 24 VDC. The 12 VDC option is available as the SN-3D model.
