Adjustable Relief Valve 6000 psi 1/4" MNPT Aluminum
The Aqua Environment 504 is an economical, small, high-pressure relief valve with excellent set pressure control over a large range. It stays bubble tight to within a few psi of set pressure and reseats bubble tight even after many vent cycles. Safety wire holes are provided for optional locking of set pressure adjustment. 0-6000 psi relief pressure. Maximum rated pressure: 6000 psi. Output pressure setting range: 900-6000 psi.

Typical Applications
- Discharge and interstage reliefs on small high pressure compressors
- Reliefs on charging lines, regulators, and manifolds
- Hydraulic system and accumulator reliefs
- Many other safety relief valve applications
¹Although the 504 is rated for pressures up to 6000 psi, the manufacturer recommends the 1607 relief valve for customers wishing to use a set pressure above 5000 psi. The 504 and 1607 valves have the same form factor but a 1607 design modification allows for a higher set pressure without pushing the spring to its limits.
