A valve for use with a fluid pump, the valve including: a valve body having an inlet and an outlet, said inlet being configured for fluid communication with the outlet via a fluid passage disposed between the inlet and the outlet; a valve orifice member disposed within the valve body and forming a portion of the fluid passage disposed between the inlet and the outlet; a tubular section having a first end configured for rigid attachment to the valve body; a plunger configured for controlled movement within the tubular section in response to at least one control signal received from a control module between at least one of a first position wherein a mating surface of the plunger is configured to sealingly engage with an orifice of the valve orifice member so as to block flow of fluid from the inlet to the outlet via the fluid passage, and a second position wherein the mating surface of the plunger is configured to not sealingly engage with the orifice of the valve orifice member so as to not block fluid flow from the inlet to the outlet via the fluid passage; and wherein said valve orifice member is separately formed from the valve body and configured to be inserted within the valve body, and, wherein an inner spring is configured for compression and expansion movement along a hollow elongate core of the plunger, an inner tube within the elongate hollow core of the plunger providing support and guidance for the inner spring as it expands and compresses and wherein the mating surface of the plunger is rigidly mounted on the end of the inner spring so that when the mating surface sealing engages with the valve orifice member, the inner spring assists in dampening the shock of impact upon closure of the mating surface against the valve orifice member, characterised in that the first end of the tubular section is configured to press against the valve orifice member within the valve body so as to secure the valve orifice member in place within the valve body when the tubular section is rigidly attached to the valve body. a valve body having an inlet and an outlet, said inlet being configured for fluid communication with the outlet via a fluid passage disposed between the inlet and the outlet; a valve orifice member disposed within the valve body and forming a portion of the fluid passage disposed between the inlet and the outlet; a tubular section having a first end configured for rigid attachment to the valve body; a plunger configured for controlled movement within the tubular section in response to at least one control signal received from a control module between at least one of a first position wherein a mating surface of the plunger is configured to sealingly engage with an orifice of the valve orifice member so as to block flow of fluid from the inlet to the outlet via the fluid passage, and a second position wherein the mating surface of the plunger is configured to not sealingly engage with the orifice of the valve orifice member so as to not block fluid flow from the inlet to the outlet via the fluid passage; and wherein said valve orifice member is separately formed from the valve body and configured to be inserted within the valve body, and, wherein an inner spring is configured for compression and expansion movement along a hollow elongate core of the plunger, an inner tube within the elongate hollow core of the plunger providing support and guidance for the inner spring as it expands and compresses and wherein the mating surface of the plunger is rigidly mounted on the end of the inner spring so that when the mating surface sealing engages with the valve orifice member, the inner spring assists in dampening the shock of impact upon closure of the mating surface against the valve orifice member, characterised in that the first end of the tubular section is configured to press against the valve orifice member within the valve body so as to secure the valve orifice member in place within the valve body when the tubular section is rigidly attached to the valve body.
