a housing, the housing including a sleeve, an inlet, and an outlet, wherein the sleeve has a sleeve flange that extends outwardly from an upstream end of the sleeve;
an insert secured to the sleeve at the upstream end of the sleeve, the insert having an insert body and an insert flange that extends outwardly from an upstream end of the insert body, wherein an outer surface of the insert body is secured to an inner surface of the sleeve and the insert flange is secured adjacent the sleeve flange, the insert defining a valve seat;
a valve plug, the valve plug having a valve head and a valve body secured thereto, the valve body having a plurality of fins that extend radially outward and slidingly engage an inner surface of the sleeve constraining radial movement of the valve plug as the valve plug moves between an open position and a closed position, wherein a downstream end of each fin in the plurality of fins includes a notch, wherein a downstream end of the valve body is radially smaller in longitudinal cross-section than an upstream portion of the valve body; and
a coil spring that biases the valve plug towards the closed position, the coil spring having a first end, a spring body, and a second end, the first end abutting the plurality of fins of the valve body, wherein the downstream end of the valve body is at least partially nested within the spring body.
