Abstract
A pressure relief valve is disclosed. The pressure relief valve comprises a body, a valve member, and a resilient member. The body includes a guide bore, a seat surface, an inlet, a first outlet, and a second outlet. The valve member is received within a portion of the body and includes a guide portion received within the guide bore, a valve seat configured to sealingly engage the seat surface, and an internal passage. The resilient member biases the valve seat into engagement with the seat surface. The valve member is moveable between a first position in which the inlet is fluidly blocked from the first outlet and the second outlet, a second position in which inlet is fluidly coupled to the first outlet but not to the second outlet, and a third position in which the inlet is fluidly coupled to the first outlet and the second outlet.
