Installation Tips

Note: The correct handling and installation of a safety relief valve is the key to avoid malfunctioning of the device.

- Clean the inlet and outlet connections to avoid impurities that could damage the sealing system.
- Avoid components that cause pressure losses (shut-off valves, pipe extensions, etc.) between the system/equipment and the safety relief valve.
- The diameter of the connection must be at least the same as the valve inlet.
- Always install in a vertical position.
- The discharge generates back pressures that must be taken into account when selecting the correct valve size and model.
- Do not use sealing gaskets that release residues.
- In steam lines, never install the valve below the pipe level.
- Please consult the particularities of installation according to the legislation in force at the final location.

Packaging:
