1.Pull-Type Relief Valve Operation
2.Primary Valve (Small)

Dual Valve Structure, Sequential System
Primary Valve Opens
Throttle lift creates a pressure difference between chambers A & B, opening the primary valve bypassing the secondary valve. this creates the initial discharge.
Secondary Valve Opens
When pressure difference in chambers A & B reach a maximum, the Primary Valve pulls the Secondary Valve open, creating a secondary discharge.
