A valve comprises a valve body, a poppet, and a pin. The valve body includes an inlet, an outlet, and a fluid flow passage therebetween. The poppet is disposed in the valve body, and is moveable between a closed position, in which the poppet at least substantially restricts fluid from flowing through the fluid flow passage, and an open position, in which fluid is allowed to flow through the fluid flow passage. The pin is disposed in the valve body, and extends at least partially into the poppet. The pin is configured to guide poppet movement in the valve body between the closed position and the open position. In this configuration, the ratio of the poppet length to diameter can be less than one.
