Dwyer Instruments A-310A Valve
The Dwyer Instruments A-310A Valve is a technical essential for any contractor working with low pressure measurement systems. This 3-way vent valve is engineered specifically for permanent installations where Magnehelic gauges or manometers are connected via rigid metal or plastic tubing. In high-stakes HVACR environments where periodic zeroing is required without breaking line integrity, the A-310A provides a reliable manual interface. Featuring a 1/8" NPT inlet and a 1/4" metal tubing connection, this 80 psi rated component replaces the legacy brass A-310 with a high-durability plastic construction that offers superior corrosion resistance in demanding field conditions.
Operating with three distinct positions—Line (gauge to source), Off (both closed), and Vent (gauge to atmosphere)—this valve simplifies the calibration of differential pressure gauges. Whether you are troubleshooting air handling units or maintaining laboratory cleanroom monitors, the A-310A instrument valve ensures accurate zeroing by isolating the pressure source and venting the instrument. The compact footprint allows for seamless mounting in A-316 or A-317 type C connections, making it a versatile HVACR accessory for any pneumatic control professional.
Key Benefits
- Simplified Calibration: Allows for safe zeroing of gauges by venting to the atmosphere without disconnecting tubing.
- Rugged Construction: Molded plastic design rated up to 80 psi provides excellent chemical and corrosion resistance.
- Precision Compatibility: Direct fit for 1/8" NPT to 1/4" metal tubing, ideal for standard instrumentation valve layouts.
- Legacy Replacement: Modern, lightweight alternative to the discontinued brass model A-310.
- System Versatility: Suitable for use with air and compatible non-combustible gases in pressure or vacuum applications.
Common Questions
What is the maximum pressure rating for the A-310A?
This valve is rated for a maximum pressure of 80 psi (5.5 bar). For lower pressure requirements, contractors often look at the A-310B which is rated for 10 psi.
Can I use this with plastic tubing instead of metal?
Yes, while designed for 1/4" metal tubing, the valve can be used with compatible plastic tubing provided appropriate compression fittings or adapters are utilized for the 1/8" NPT and tubing interfaces.
Does this valve allow for simultaneous venting of both ports?
The 3-way configuration is designed to isolate the pressure source while venting the gauge port. In the "Off" position, both ports are closed to prevent any flow or pressure loss from the main line.
