## Overview

The Control Devices P5050-1EP is a brass in-tank poppet-type check valve designed for 1/2" NPT female to male connections. Engineered for industrial-grade durability, it withstands pressures up to 450 psi and temperatures up to 400°F. Featuring a PTFE poppet and stainless steel spring, it ensures quiet, reliable one-way flow control, making it an essential upgrade for professionals seeking to optimize compressor performance and longevity.

## Description

This Control Devices in-tank check valve is a poppet-type valve, and may be disassembled for cleaning or repair The valve body is made of brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability. Brass can be connected to copper, brass, plastic, aluminum, and welded steel. This valve has a glass-filled polytetrafluoroethylene (PTFE) poppet with eight discharge holes for quiet operation, and stainless steel spring. It has a compression connection on one end for a leak-proof connection without the need for additional joining preparations, and female NPT threads end on the other for connecting to male threaded pipes, creating a tighter seal than straight threads. The maximum pressure rating is 450 pounds per square inch (psi), and the maximum working temperature is 400 degrees Fahrenheit.Check valves have two ports and restrict the flow of fluids and other loose materials through a pipe or passageway to one direction. Flow enters through one port and exits through the other, closing when flow reverses or stops. Two common types of check valves are ball cone valves and swing check valves. A ball cone valve utilizes a spring-loaded ball seated against a cone-shaped interior surface to stop the flow of fluid in a forward direction, and a swing check valve has a movable disc on a hinge to block reverse flow. Check valves are rated by their cracking pressure (the minimum upstream pressure required for the valve to operate), and they are used in various water, gas, air, and steam lines.Control Devices manufactures specialty valves, nozzles, and condensate traps. The company, founded in 1963 and headquartered in Fenton, MI, meets ASME standards.

Review: Great In-tank check valve - Great product! Is and works exactly as described!
Review: 1/2" NPT Male-Female - I rebuilt my old 60 gl. single stage Porter Cable compressor that I call "Franken-Pressor" recently , adding larger 1/2" NPT "Black Pipe" lines , pump and a true 5hp. Continuos Duty Leeson Motor . This allows the compressor from getting so hot they go Nuclear and literally have a melt down (mine did twice in 10 years of heavy use).The compressor needed a check valve to relieve the back pressure on restart (without the valve my compressor (not a shop duty but great for home use) could not restart period (almost "Smoke-Checked" the Leeson with cut-off set at 125 psi). I finally figured out I needed a one-way check valve so there was no load on the electrical motor from the compressed air backing up into my twin cylinder pump , and this valve is rated to 450psi back pressure! Finding a valve was a bit of a chore as all lines were 1/2" steel pipe for greater volume . So far I've burned 2 pumps up and almost burned up my new Leeson 5hp. motor with those dinky 1/2" copper tube lines (WHAT A JOKE !) . I do body work etc. and I really "tax" it's capability . Yeah , I know,, I need a Two-Stage but My Ol' Man used to say "Wish in one hand and do something really "foul" in your other hand and see which fills up faster" ! ;-) I initially found this valve on a well known Industrial Supply site . Came over to desertcart and they had it ! Much quicker delivery (2 days) through desertcart.com and cheaper too . I also ran the air charge inlet line to the bottom of the tank instead of right next to the air outlet for less moisture in my lines . A heads' up for you advanced and begining DIY'rs , if you decide to get more volume from your compressor (which if like me you can't afford $1,200+ for a 2-Stage Compressor) and make it run cooler with larger lines you'll need to build a "chamber for the valve to fit 1/2" lines ,it WILL NOT fit inside 1/2" without choking off the air supply ! Get yourself 2- 3/4"x 1/2" female NPT reducer couplings (They're Bell Shaped) , 1- 3/4"x3-4" NPT Nipple , and 1- 1/2" coupler . You'll also need to lay down the tank to re-thread/tap the drain to 1/2" NPT. You may need to find a plumbing shop with the right drill size as the drill bit is $60-$80.00+ , and the Tap price will make you "Pucker-Up" as well .Search "Fastenal" or "Grainger" get the numbers and come over here to desertcart ,good bet they'll have it cheaper and the same brand as my Valve turned out to be . Big expense unless you think your're only going to use it once . Don't go cheap on the bit or tap (ie:H-Freight etc.). Get a quality Tap and drill otherwise you end up with a snapped tap or bit in your tank NOT FUN !!!!! This a great product and conversion that will strenghten and add much more life to your single-stage compressor . Signing off now, "Bogie"
