<p>The valve body (28) is hollow, bush-shaped and surrounds the flow channel (22). The area (A) subjected to residual pressure (p) is designed to be small, such that up to a maximum residual pressure (pmax) of about 300 bar, the valve body can be brought into the open position. This is achievable from the closed position, by manual coupling against the residual pressure (p), acting against the resultant valve force (F) acting on the pressure area (A).</p> |
