This industrial-grade stainless steel proportional relief valve offers dependable overpressure protection for critical instrumentation and high-pressure fluid systems. Designed in a compact 90-degree angle configuration with a male inlet and female outlet, it opens gradually to safely bypass excess system pressure. Featuring an adjustable spring bonnet and integrated panel-mounting nuts, this valve ensures precise setting repeatability in harsh liquid, vapor, or gas processing environments.
