Relief valves and methods for installing the same

摘要

A relief valve can include a valve body, a valve member, a valve stem, and a magnetic member. The valve body can define a flow path that extends between a first port and a second port. The valve body can include a valve seat disposed between the first port and the second port. The valve member can be disposed between the valve seat and the second port of the valve body. The valve member can move along an actuation axis. The valve stem can be coupled to the valve member. The valve stem can extend from the valve member towards the first port. The magnetic member can be coupled to the valve member and can generate a magnetic force that urges the valve member to seal with the valve seat of the valve body.
