  • Product typeDrain Components
  • Regulates pressure from 0 to 25 psi for precise control
  • Brass body withstands up to 300 psi maximum pressure
  • Operates reliably at temperatures up to 140 degrees Fahrenheit
  • Buna-N seals ensure leak-free performance in industrial applications

Pressure Regulator 0-25 psi

The Watts Series 560 pressure regulator is a brass-bodied valve designed for industrial fluid systems. It accepts 1/8 inch FNPT connections on both inlet and outlet and includes a 1/8 inch gauge port for monitoring.

Adjustment Range Limits

The regulator adjusts outlet pressure from 0 to 25 psi, so it cannot serve applications that require higher downstream pressure. Its maximum inlet rating is 300 psi, which sets the upper boundary for supply pressure in the system.

Temperature and Media Capacity

Buna-N seals and a 140 °F maximum temperature rating suit the valve for water, air and compatible oils in general industrial use. It is not intended for steam, aggressive chemicals or processes that exceed the stated temperature limit.

Questions about this item

Should I choose the 0-25 psi version or a different pressure range?

The 0-25 psi adjustment range suits low-pressure industrial systems; select a higher range only if your application requires pressure above 25 psi.

What does the 25 psi adjustment range mean once the regulator is installed?

It lets you set downstream pressure anywhere between 0 and 25 psi while the brass body handles up to 300 psi inlet pressure.

How does the FNPT connection affect installation?

The 1/8 inch FNPT threads accept standard male NPT pipe fittings for a direct, leak-tight connection without adapters.
