Specification

DESCRIPTION
Our relief valve is meticulously engineered to achieve the rated pressure by adjusting the robust spring force, facilitating unrestricted flow from P to T as the pressure at P reaches the designated valve setting. In contrast, it allows free flow from T to P with minimal pressure. This valve is celebrated for its rapid response and impressively low internal leakage, ensuring flawless performance in demanding applications.
