Zusammenfassung:	FIELD: arrangements for cutting-off. ^ SUBSTANCE: valve has housing. The housing receives heat-reflecting member which moves between the first and second position. In the first position, the heat-reflecting member overlaps open sealing surface of the soft seal. In the second position, the heat-reflecting member does not close the open sealing surface of the soft seal and allows the open sealing surface of the soft seal to be in a gas-tight contact with the sealing surface of the closure member pressed to it. The heat-reflecting member has internal cooling circuit and made of a ring. The ring is mounted for rotation around the axis of rotation between the first and second position. The axis of rotation of the heat-reflecting member is parallel to the central axis and at a distance from the seat side. ^ EFFECT: enhanced efficiency at high temperatures. ^ 15 dwg
