Technical Information Fig. 573 - 65-200mm

The Roma Fig. 573 is a direct-acting, single-seated, spring-regulated surplus valve designed to automatically relieve excess system pressure.

System pressure acts on the valve plug to modulate valve opening in accordance with the regulating spring setting, ensuring stable and reliable pressure control.

The Fig. 573 features a balanced outlet, minimising the influence of downstream pressure on valve performance.
