Abstract

The present invention relates to a valve (30) intended to control the pressure in a pipe (32) in which a gas is conveyed. The valve comprises a valve body (34) that has through apertures (36). The valve housing (35) comprises a spring (58) arranged in a chamber (42) in which the valve body is movable. The valve comprises further a control pressure conduit (56) for feeding of the gas that is connected to the chamber. The spring (58) is arranged to spring-load the valve body (34) at a primary pressure of the gas such that the valve body is displaced in a sealed position over the apertures (36). A secondary pressure of the gas, lower than said primary pressure, that provides a low pressure ratio between the surrounding atmospheric pressure and the secondary pressure, reduces the spring-loading on the valve body such that the valve body (34) is moved in the chamber (42) and at least partially uncovers the apertures (36) whereby gas can be exhausted. The wall sections (38) of the valve housing (35) forms an extended part of the pipe (32).
