Abstract

A valve device is intended to communicate with a space (8) for pressurized fluid through a first connection line (6) and allow outflow of pressurized fluid and communication with a pressurized-fluid source, respectively through a second connection line (5). The valve device is arranged to maintain a residual pressure in the pressurized-fluid space but allow supply of pressurized fluid to the space upon application of pressure on the second connection line. The valve device comprises two non-return valve units (9, 10), one of which closes against pressurized-fluid outflow from the space when the pressure therein falls below a certain level whereas the other opens upon said application of pressure on the second connection line. The non-return valve units are located in two different chambers (11, 12) in a body (3) of the valve device. Each of these chambers is accessible from the outside of the body through an opening (13 and 14 respectively) of its own separated from the outer orifices of the connection lines in order to insert and remove, respectively, and possibly also adjust the valve units or parts thereof through theses openings.
