PROBLEM TO BE SOLVED: To provide a panel valve that uses a gasket with resistance to high temperature and high pressure which is preferable in heat resistance and pressure tightness and can easily set the gasket packing between a valve-side connection face and a block-side connection face while holding the gasket packing at proper position. SOLUTION: In this panel valve A, a valve-side connection face 4 is connected to a block-side connection face 8 with the surfaces thereof being in contact so that the valve-side communication openings 23, 24 fit to block-side communication openings 73, 74. An annular recess 25 for housing and holding the gasket packing 5 at the proper position is formed at the rim of the valve-side communication opening. COPYRIGHT: (C)2004,JPO
