The present invention relates to a valve assembly. The valve assembly includes a valve member and valve seats having a ring shape. The valve member includes a valve body and an opening. The valve body has a plurality of ports to pass a fluid, and has a receiving groove. The opening is received in the receiving groove of the valve body, and corresponds to the ports. Each of the valve seats is provided on the entrance of each of the ports of the valve body to face the valve member. Each of the valve seats includes: a sealing ring member configured to be elastically deformed by being pressurized; a low friction guide film attached to a surface where the sealing ring member is in contact with the valve member; and a ring-shaped supporting member coupled to an opposite side of the guide film in the sealing ring member.
