AIR-COMPRESSOR In-Tank Check Valve 3/4 MPT x 1/2 Compression Part# 6x213
Control Devices Corporation
Part# 6x213
Economical, reliable brass in-tank check valves for compressors, air tanks.
Fluoropolymer poppet, stainless steel springs.
Check valves have been tested to 400 Degrees F. for Air; rated 400 PSI Max. pressure.
External threads are coated with Loctite Vibra-Seal 516 dry type thread sealant.
Inlet or Air Line from compressor fitting: 1/2" O.D. Compression Fitting Male
Outlet or tank side fitting: 3/4" Male NPT.
The bottoms threads of this valve are: 3/4" Male Pipe Thread
This is the side that screw into the tank: 3/4" MPT.
The top of this valve where the discharge tube or line connects to is made for 1/2" O.D. Compression Nut.
The threads for the bleed line is 1/8" Female "NPT" thread and comes with a plug which can be left in or removed to connect to the bleeder line or unloader line.
Also includes a 1/8 barb adapter
For Industrial and Commercial applications.
INLET: 1/2" O.D. Compression Male.
OUTLET:  3/4" Male N.P.T.
This is the check that screws into the air compressor tank.
When this check valve goes bad the air keeps coming out the relief valve on the pressure switch.
This check valve is suppose to hold the pressure in the tank and allow the pressure between the outlet of the compressor and the inlet of the tank to release.
This happens so the compressor does not start with a load or a head pressure on the discharge side.
This valve should allow flow one way, thus the term "CHECK-VALVE" is used.
If your air compressor runs fine but the minute it shuts off the air keeps coming out the pressure switch them you have a bad check valve.
#5346K61, 1/8" NPT male x 1/8" barb.
06110-1208, = 1/2" NPT female x 3/4" NPT male.
