Specification

DESCRIPTION
Engineered to perfection, our valve achieves its rated pressure through meticulous adjustment of spring force, facilitating seamless flow from P to T as the pressure at P approaches the valve setting. It also ensures unobstructed flow from T to P at remarkably low pressure. Designed for excellence, the valve promises swift response and minimal internal leakage.
