Claim 0:
1. A method for assembling a valve, the valve comprising: a valve body, the valve body comprising a first fluid port, a second fluid port and a fluid path providing fluid communication therebetween; a housing; a moveable member configured to be actuated to vary a flow restriction in the fluid path by advancing a sealing member toward or away from a valve seat of the valve; a biasing member configured to bias the moveable member toward or away from the valve seat; and a pressure compensation membrane configured to provide at least one surface on which a pressure from at least one of the first and second fluid ports can act to provide a pressure compensating force to the moveable member, the valve being configured such that fluid pressure from the first fluid port or the second fluid port acts on a side of the pressure compensation membrane facing away from the valve seat, the method comprising the steps of: providing a base member comprising an abutment for receiving at least a first of the biasing member and the pressure compensation membrane, inserting the biasing member, pressure compensation membrane and moveable member into the housing, assembling the biasing member and the pressure compensation membrane with the base member, and affixing a fixing member to the base member to retain both the biasing member and the pressure compensation membrane between the fixing member and the abutment, wherein the base member is at least a portion of the housing, and wherein the fixing member is at least a portion of the valve body and the method comprises introducing the fixing member into the housing to affix the fixing member to the housing.
