The GP-2000 series externally piloted design separates the sensing and control functions, allowing the pilot to sense downstream pressure independently and modulate the main valve accordingly. This results in tighter pressure control and more consistent performance compared to direct-acting designs — making it an ideal choice for systems where precise steam pressure regulation is critical.
