30D13 Pilot Operated Pressure Excess Regulator


Product Description

The valve, made from valve body, actuator and one pressure-preset spring, applies internal pressurizing structure, automatically adjusts and stabilizes the pressure by using the pressure change of medium itself. It is applicable for steam, weak corrosive gas or low-viscosity liquid, acting the upstream pressure control in the pipeline, when the upstream pressure rises up, the valve is open to relieve the pressure. Compared with direct-acting type, this valve has larger flow capacity and is suitable for large flow work conditions.
