IMPA: 590822

Air Line Pressure Regulator PT3/8 – IMPA 590822

This air line pressure regulator (IMPA 590822) is designed for marine pneumatic systems to maintain a constant downstream pressure. Featuring a PT 3/8 connection, it is ideal for use with compressed air tools and pipelines on board vessels. The non-relief valve design ensures reliable pressure control without venting, making it suitable for closed-loop applications.

The regulator delivers an adjustable set pressure range from 0.05 to 0.85 MPa (approximately 7 to 123 psi), with a maximum operating pressure of 9.9 kgf/cm² (141 psi) and maximum temperature of 60°C (140°F). A pressure gauge is included as a standard accessory for easy monitoring. Compact and robust, this unit is a cost-effective solution for maintaining consistent air pressure in marine environments.

Frequently Asked Questions

What is the thread size and type of this regulator?

The regulator has a PT 3/8 thread, which is a standard tapered pipe thread commonly used in marine pneumatic systems.

Can this regulator be used with an existing compressor without a relief valve?

Yes, this is a non-relief (non-venting) type regulator, meaning it does not vent excess pressure to the atmosphere. It is designed for closed-loop systems where constant pressure is required without air loss.

What is the maximum inlet pressure this regulator can handle?

The maximum operating pressure is 9.9 kgf/cm² (141 psi). Exceeding this may damage the unit.

Does the pressure gauge come with the regulator?

Yes, a pressure gauge is included as a standard accessory for easy monitoring of the set pressure.
