About :

The pilot-operated pressure regulating valves are used for pressure reduction on steam mains and other process equipment. Pilot-operated regulators will maintain a constant and accurate downstream pressure regardless of fluctuations in supply pressure or usage. These regulators can be supplied with an optional internal sensing line which simplifies installation. Piston-actuated regulators are more compact than Diaphragm-actuated regulators. The 403 Series contains all stainless steel internals for high-pressure applications up to 450 PSIG. The Double-Spring option is available for a wider range of reduced pressures.

Also Known As:

Direct Acting Pressure Regulator, Direct Acting Pressure Reducing Valve, Spring-Loaded Pressure Regulator, Direct Spring Operated Regulator, Mechanical Pressure Regulator.

Specification:

Features:

• Pilot-operated regulators minimize outlet pressure fluctuations even when load varies

• Internal Sensing option (If requested, the regulator can be modified to internally sense
pressure, eliminating the need for an external sensing line)

• Ductile Iron body to handle increased pressure and temperature

• Hardened stainless steel seat and disc (55 Rc)
