Aqua Environment 1607 1607 Series Relief Valve 0-7500 PSI Relief Pressure

The model 1607 is an economical, small, high pressure relief valve having excellent set pressure control over a large pressure range to 7500 PSI. It stays bubble tight to within a few PSI of set pressure and reseats bubble tight even after many vent cycles. It is a similar but improved version of time tested 504 relief. It permits a higher maximum pressure setting, provides a larger flow area and is less likely to be damaged by small amounts of debree passing through it. Safety wire holes are provided for optional locking of set pressure adjustment.

Features:

• Relief valve
• 0-7500 PSI relief pressure
• Soft seal provides excellent sealing and resealing
• Unique design eliminates seal damage or extrusion
• Easy in-field maintenance
• Design assures excellent repeatability without lubricants

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

Installation

Use pipe thread sealant Teflon tape on inlet and outlet threads. Avoid over torquing pipe thread. Normal torque applied with a 6 or 8 inch long wrench is ample. Use ample Teflon tape - 3 or 4 turns, not 1 or 2 turns. It is important to maintain piping internals free of particulates such as metal chips, dirt, weld slag, etc. If present these will tend to lodge in the relief valve when it opens causing damage to the seat and leakage. Since it is difficult to keep piping completely clean during assembly it is advisable to blow high velocity air through the system and out the relief valve port just prior to installing it. This can normally clean the system of particulates. A high pressure air tank can provide a strong flow for this cleaning operation. Suitable ear and eye protection should be used when flowing high pressure air. It is NOT advisable to install any type of filter before the relief valve. A filter could become clogged disabling the safety function of the relief.
