Frequently asked questions
Common questions about DRAIN-ALL from 3G Electric.
What is the typical operating temperature range for DRAIN-ALL automatic drain valves?
DRAIN-ALL automatic drain valves, such as the PH50-0NAAA and DH50-0LAAA models, are rated for an operating temperature range of 34°F to 170°F (approximately 1°C to 77°C). This range covers most indoor industrial environments where compressed air systems operate. For applications outside this range, verify compatibility with the specific model's datasheet or consult 3G Electric for alternative options.
What pipe sizes are available for DRAIN-ALL drain valves stocked by 3G Electric?
The DRAIN-ALL automatic drain valves available through 3G Electric feature a 1/2-inch NPT pipe size. This is a common standard for connecting to compressed air filters, receivers, and drip legs. The drain outlet diameter is also 1/2 inch. If your system requires a different pipe size, check the full DRAIN-ALL catalog or contact 3G Electric for availability of other configurations.
Can I rebuild a DRAIN-ALL drain valve instead of replacing it?
Yes, DRAIN-ALL offers overhaul kits, such as the 770110 kit, which allow you to rebuild automatic drain valves. These kits typically include seals, gaskets, and other wear components. Rebuilding can extend the valve's service life and reduce replacement costs. Ensure the kit is compatible with your specific valve model before ordering. 3G Electric stocks these kits for convenient procurement.
What is the difference between DRAIN-ALL models PH50, DH50, and RH50?
The PH50, DH50, and RH50 series are different families of DRAIN-ALL automatic drain valves. While all share a 1/2-inch NPT pipe size and similar temperature range, they differ in actuation type and operational characteristics. For example, some models may be normally open or normally closed, or have different timer settings. Refer to the manufacturer's documentation for exact specifications, or contact 3G Electric for guidance on selecting the right model for your application.
Are DRAIN-ALL drain valves suitable for outdoor use?
DRAIN-ALL automatic drain valves are designed for indoor industrial use, with an operating temperature range of 34°F to 170°F. Outdoor exposure to freezing temperatures below 34°F could cause condensate to freeze and damage the valve. For outdoor installations, consider adding insulation or heat tracing, or select a valve rated for lower temperatures. Verify with the manufacturer's specifications for your specific model.
