Auto Drain Valve 1/4 NPT 75 gpm
The SPEEDAIRE 53RG50 is a timed electric auto drain valve designed for hydraulic and compressed-air systems. It removes condensate automatically at a drain rate of 75 gpm through a 1/4 inch NPT port.
Adjustable Cycle 0.5 min to 99 hr
The valve offers an adjustable drain cycle ranging from 0.5 minutes to 99 hours with a purge time of 0.5 to 10 seconds. It operates at 115 V, 60 Hz and draws 0.3 A with a maximum pressure rating of 725 psi.
Suits 1/4 NPT Systems up to 725 psi
This unit fits installations requiring a 1/4 inch NPT connection and IP65 protection within a 14 to 140 degrees F temperature range. It is not for systems needing a larger drain port, higher voltage, or a pressure rating above 725 psi.

Questions about this item
How does the 75 gpm drain rate translate to actual condensate removal in a compressed-air system?
The valve can discharge up to 75 gallons per minute during its purge cycle, clearing large volumes of water and oil quickly when the timer opens the 1/4-inch drain port.
What does the 1/4-inch NPT connection limit in terms of pipe compatibility and flow?
The 1/4-inch NPT inlet and outlet restrict piping to that thread size, so flow capacity is governed by the 75 gpm rating and the 725 psi maximum pressure of the brass body.
What are the physical dimensions and mounting requirements for installing this valve?
The brass body measures 3 13/16 inches high, 1 45/64 inches wide and 4 inches deep, with a 1/4-inch NPT port for direct inline mounting and an IP65-rated enclosure.
