Zusammenfassung:	A liquid control valve including a body comprising an inlet port, an outlet port, and an interior chamber, the body defining a liquid passageway between the inlet and outlet ports. Also included is a plunger comprising a groove provided on an external wall, the plunger being configured to reciprocate within the interior chamber of the body between a first position where the valve is closed and a second position where the valve is open. Also provided is a sealing arrangement within the groove configured to seal between the plunger and the interior chamber of the body. The sealing arrangement includes a first sealing element on the external wall of the plunger and spaced apart from an inner wall of the internal chamber, and a second sealing element on the inner wall of the internal chamber and spaced apart from the external wall of the plunger.
