Timed Electric Auto Drain Valve

Speedaire auto drain valves are designed for draining the oil and condensed water from moisture separators, filters, aftercoolers, dryers and air receiver tanks. These Speedaire auto drain valves come equipped with an adjustable electronic timer for automatic opening & closing of valves. Speedaire auto drain valves feature filter ball valves for controlling the high-pressure flow rates and reducing the frictional losses. Models from 38X Series of these Speedaire auto drain valves, such as 38XT33 and 38XR59 can handle temperatures ranging from 35 to 95 degrees F and models from the 13X Series, such as 13X524, 13X525, 13X526 and 13X528 have an operating temperature range between 14 and 140 degrees F.

Uses

Speedaire auto drain valves drain the oil and condensed water from filters, moisture separators, dryers, aftercoolers and air receiver tanks.

Working Mechanism

Speedaire auto drain valves work by allowing the condensate to gravity feed into the valve's condensation reservoir. When the liquid in the reservoir of these Speedaire auto drain valves rises to a point where the float lifts off the seats, control air pressure is sent to the pneumatic piston to open the normally closed 3/4 inch ported ball valve.

Features

  • Speedaire auto drain valves are ideal for draining the condensed water and oil from filters, dryers, moisture separators, aftercoolers and air receiver tanks.
  • These Speedaire auto drain valves have an adjustable electronic timer for automatic opening and closing.
  • Speedaire timed electric drain valve comes equipped with a filter ball valve for reducing the frictional losses and controlling the high-pressure flow rates.
  • These timed electrical auto drain valves are made of brass / 316 stainless steel for structural rigidity and resisting corrosion on exposed surfaces.
  • Models from the 13X Series of these Speedaire auto drain valves, such as 13X524, 13X525, 13X526, 13X528 have an operating temperature range between 14 and 140 degrees F, while the models from 38X Series, such as 38XT33 and 38XR59 can withstand temperatures ranging from 35 to 95 degrees F.

Compatible Accessories

  • Speedaire Y-Strainers: These are Y-shaped devices used for mechanically removing unwanted solids from gas, liquid or steam lines using a wire mesh or perforated straining element. They are commonly used in pipelines for protecting pumps, steam traps, meters, control valves and regulators.

Installation

  • Speedaire auto drain valves should be installed according to the direction of flow to the atmosphere.
  • In cases where normal installation is not possible, these Speedaire auto drain valves are piped into a higher discharge point while ensuring that a trap test port is present to check for plugging. The user must also ensure that the blow-down cycle is adjusted for an effective increase in volume.
  • The user must ensure that the pipe tape, pipe dope, metal chips or scale are trapped before the drain valve seat. Also, the Y-strainer should be installed before the drain.

Frequently Asked Questions

How do auto drain valves work?

Auto drain valves allow the condensate to settle down into the condensation reservoir of the valve. The controlled air pressure is sent to the pneumatic piston for opening the typically closed 3/4 inch ported ball valve when the liquid present in the reservoir rises to the point where seats get lifted by the float.

What is an auto drain?

An Automatic drain is a 2/2 way valve that closes when the system is subjected to a particular pressure. The drain valve opens when liquid gets accumulated and allows the float to rise on depressurisation.

Can we leave the air compressor drain valve open?

Ideally, you should drain the moisture tank after use. If the unit remains unused for a while, leave the drain valve open till the time you use it again. This will completely drain out moisture and prevent the inner surface of the tank from corrosion.

Are Speedaire auto drain valves dustproof?

Yes, Speedaire timed electric auto drain valves or Speedaire drain valves offer IP65 rated enclosures to provide excellent dust resistance.

What is the pressure handling capacity of Speedaire timed electric auto drain valves?

Speedaire auto drain valves withstand pressures ranging from 250 to 4000 psi.

What happens if the air compressor is not drained?

If the air compressor is not drained properly, the drain gets rusty and will not be functional after a while. Also, the tank fills with water instead of air, and water will flow out of the air hose.

How often should you drain water from the air compressor?

Users should drain the compressor's tank daily, whether manually or automatically. Water build-up in the tank can cause the bottom of the tank to rust. If you find yourself forgetting about draining your tank, you should purchase an electronic drain valve.

What safety instructions are recommended for users while operating Speedaire auto drain valves?

To ensure the safe and long-lasting performance of Speedaire auto drain valves, such as auto drain valve, the user must ensure proper handling of the product. Non-compliance with instructions will void the product's warranty. These Speedaire auto drain valves are designed for draining condensate from compressed air systems.

For added safety, the following points should be kept in mind:

  • Observe generally accepted but valid safety rules while planning, installing and using these timed electric auto drain valves.
  • Take suitable measures for preventing accidental operation and damage to these valves.
  • Do not attempt to disassemble these valves or lines in the system when they are under pressure.
  • Always depressurise the compressed air system before operating these Speedaire auto drain valves.
  • Installation as well as maintenance works must be carried out in accordance with the appropriate codes of practice & local regulations.

What is a timer drain valve?

Timer operated drain valves are cost-effective and reliable valves that periodically open the drain's valve for a specific period. The valve may be open for a few seconds every hour to remove the collected condensate.
