A valve joint, in particular, a measuring valve joint for fluid systems with high working pressures, comprises a connector bushing under line pressure having a spring-loaded and mechanically operable check valve in a bore. A cylindrical valve body in the bore presses its packing shoulder against a sealing ring consisting of an elastomeric material in the closed state of the valve. A sealing liner and the valve body form a sealable flow channel arranged in the connector bushing. Further seals are arranged downstream and/or upstream from the sealing ring. Upon the opening of the valve body the further seals terminate their sealing function only after the lifting of the sealing ring from the packing shoulder and preferably in a delayed manner.
