Aqua Environment 1310 1310 Series Back Pressure Regulator 1/4" NPT Inline Economical Not Adjustable

Also known as a priority valve, the model 1310 is a fully balanced, economical regulator. It serves a wide variety of uses, however its main use is on small compressors. The regulator will improve moisture separator efficiency and filter life as much as 450%. This is done by maintaining pressure in the separator and filter at about 1800 PSI when tank pressure is lower.

Features:

• Economical, inline, priority valve for small compressor systems.
• Back pressure regulator
• 1/4 in. NPT
• Inline
• Economical
• Not adjustable.

Installation

Use a suitable pipe thread sealant such as Teflon tape on the inlet and outlet ports. Connect the inlet to the source gas such as a compressor. The regulator is NOT shipped oxygen clean and should NOT be used for oxygen service as provided.

Operation

In operation the back pressure regulator will maintain its set pressure upstream and allow just enough gas flow to hold this pressure. Set pressure is pressure at the inlet port when gas is flowing through the regulator. The gauge connected to the outlet gauge port does not read set pressure. It reads pressure of the tank being filled down stream of the regulator.

Maintenance and repair caution

Routine maintenance is generally not required. Under extended or severe operation it is helpful to re lubricate the poppet seal item 10. To disassemble, remove cap 2 from body 1. Internal parts (items 3, 4, 5, 8, 9, 10, 11, 12) can then be removed by inserting a small rod in outlet and pushing parts out. The seat (item 6) can be removed from the cap using a straight blade screwdriver. Use a magnifying glass to inspect the seat sealing area for damage. Replace damaged items. To reassemble, install lower seal 9 in body, install upper item 9 and seal 10 on guide 3 then insert into body 1.

Fully pack area between the guide and seal (item) 10 with grease. Use Cristo-Lube MCG 121 grease or equivalent. Install seal 8 on cap 2 then screw into body. Assemble items 4, 5, 11, and 12. Use grease (MCG 121) between 4 and 5 to hold sub-assemble together. Insert this sub-assembly into cap then install seal 7 on seat 6 and screw into cap. Be sure poppet item 5 is centered to avoid damaging seal 10. Access leakage can occur internally between the inlet and outlet resulting in a drop in set pressure. This is generally due to dirt or other particulates damaging the seat 6.
