Boiler Steam Pressure Control

Introduction

Pressure and Temperature Control Valves | Pilo

Pilot operated pressure regulating valves are commonly used for two applications within boiler feed systems: pressure control for pressurized deaerators, and temperature control for atmospheric feed tanks. When used on a deaerator, the main regulating valve is paired with a pressure pilot to create a pressure reducing valve.
