About DRAIN-ALL

DRAIN-ALL is a product line of automatic drain valves and related service components used in compressed air systems. The brand's valves are designed to remove condensate from air lines, receivers, dryers, and filters without manual intervention. The product family includes pneumatically actuated and air-operated drain valves, along with overhaul kits that contain seals, gaskets, and wear parts to restore valve function. These components are typically specified by plant engineers and maintenance teams who need to prevent moisture carryover, corrosion, and freeze damage in pneumatic circuits.

The DRAIN-ALL valves supplied by 3G Electric are configured with 1/2 in NPT pipe size and 1/2 in drain outlet diameter. Operating temperature range for the listed models is 34° to 170°F. The valves are actuated by compressed air or pneumatic signal, depending on the model. For example, the RH50-0LAAA and DH50-0LAAA are air-operated automatic drain valves, while the PH50-0NAAA and PH50-0MAAA are pneumatically actuated. Cycle time for the DH50-0LAAA is listed at 10 seconds. These specifications make the valves suitable for a range of industrial compressed air systems where consistent condensate removal is required.

In addition to complete valves, 3G Electric stocks overhaul kits such as SKU 35MN80. These kits include seals, gaskets, and wear components to service DRAIN-ALL valves, extending service life and reducing unplanned downtime. The kits are identified by compatibility with the DRAIN-ALL brand and are intended for maintenance activities in production environments. The country of origin for the overhaul kit is the USA, though this is subject to change based on supply chain factors.

3G Electric supports the DRAIN-ALL line with global logistics, product datasheets, and multiple SKUs. The company provides quotation and order fulfillment for these pneumatic components, serving maintenance managers and procurement specialists who require specific part numbers and technical specifications. The product data available includes manufacturer part numbers, pipe sizes, temperature ranges, and catalog page references, allowing buyers to match components to their existing systems. 3G Electric does not manufacture DRAIN-ALL products; it distributes them as part of its industrial equipment catalog.

The DRAIN-ALL product range is focused on condensate management in compressed air systems. The valves are not intended for use with liquids other than condensate from compressed air, and they are not rated for temperatures outside the stated range. Installation typically requires a 1/2 in NPT connection, and the valves operate using the system's compressed air supply or a separate pneumatic signal. Maintenance intervals depend on air quality and duty cycle, but the availability of overhaul kits allows for refurbishment rather than replacement in many cases. 3G Electric provides these components to industrial facilities worldwide, with documentation to support specification and installation.

Guides & Resources

Frequently asked questions

Common questions about DRAIN-ALL from 3G Electric.

What is the operating temperature range for DRAIN-ALL automatic drain valves?

The DRAIN-ALL automatic drain valves listed by 3G Electric, including models RH50-0LAAA, DH50-0LAAA, PH50-0NAAA, and PH50-0MAAA, operate within a temperature range of 34° to 170°F. This range is specified for the valve components and should be observed to ensure proper function. Temperatures outside this range may affect seal performance and cycle reliability. The valves are intended for compressed air systems where condensate forms within this temperature band. For applications with higher or lower temperatures, consult the manufacturer's technical data or contact 3G Electric for assistance in selecting an appropriate model.

What is included in the DRAIN-ALL overhaul kit SKU 35MN80?

The DRAIN-ALL overhaul kit, SKU 35MN80, contains seals, gaskets, and wear components necessary to service DRAIN-ALL pneumatic drain valves. It is designed to restore proper drainage function and prevent moisture buildup in compressed air systems. The kit is compatible with DRAIN-ALL brand valves and is used during maintenance to replace worn parts. The country of origin for this kit is the USA, though this is subject to change. 3G Electric supplies this kit as a standalone maintenance item. It does not include a complete valve; it is intended for refurbishment of existing valves.

What is the pipe size and drain outlet diameter for DRAIN-ALL valves?

The DRAIN-ALL automatic drain valves currently listed by 3G Electric have a 1/2 in NPT pipe size and a 1/2 in drain outlet diameter. This specification applies to models such as RH50-0LAAA, DH50-0LAAA, PH50-0NAAA, and PH50-0MAAA. The 1/2 in NPT connection is a common size for compressed air system components, allowing integration with standard piping. The drain outlet diameter determines the flow rate of condensate removal. When selecting a valve, verify that the pipe size matches your system's connection and that the drain outlet is adequate for the expected condensate volume.

How does the DRAIN-ALL DH50-0LAAA valve operate?

The DRAIN-ALL DH50-0LAAA is an air-operated automatic drain valve. It uses compressed air to actuate the valve mechanism, which opens to discharge condensate from the system. The valve has a 1/2 in NPT pipe size and a 1/2 in drain outlet diameter. Its operating temperature range is 34° to 170°F. The cycle time for this model is listed as 10 seconds, meaning it opens for a set period to drain accumulated condensate. The valve includes an install kit and trap. It is designed for automatic operation, reducing the need for manual draining. 3G Electric supplies this model with manufacturer part number DH50-0LAAA.

Are DRAIN-ALL valves suitable for outdoor compressed air systems?

DRAIN-ALL valves are rated for operating temperatures between 34° and 170°F. If an outdoor compressed air system experiences temperatures below 34°F, the valve may not function correctly, and condensate could freeze. For outdoor installations, the valve should be protected from freezing conditions or the system should be designed to maintain temperatures within the rated range. The valves themselves do not carry an IP rating in the provided specifications, so enclosure protection may be necessary in wet or dusty environments. Consult the installation guidelines and consider additional protection if the valve is exposed to the elements.

Does 3G Electric supply DRAIN-ALL products?

Yes — 3G Electric (S) Pte. Ltd. supplies DRAIN-ALL products. We stock the DRAIN-ALL catalog and supply genuine factory-original products with full manufacturer warranty and technical support.
