About:

Direct-operated pressure regulators with heavy-duty cast iron bodies and built-in internal strainers are designed for durability and versatility in a wide range of low-to-moderate flow applications. Commonly used in systems such as small heaters, humidifiers, hospital equipment, and tire molds, these regulators offer reliable performance across various general-purpose settings. They operate without the need for an external sensing line, simplifying installation and maintenance. The downstream pressure is adjusted by turning an easily accessible screw with a locknut, which alters the spring force acting on the diaphragm. Multiple spring ranges are available to accommodate different pressure requirements, ensuring precise control and system stability.
