ABSTRACT:
A valve with pressure compensation via two valve bodies (9, 10), which are arranged on a connecting rod (11 ) in the same direction, and which come to lie on the corresponding valve seats (7, 8) in the closed position in the same direction via deforming zones. The tightness between the valve bodies and the corresponding valve seats is increased, and the closing force required for sealing is reduced by deforming zones located between the upper valve body (9) and the upper valve seat (7), as well as between the lower valve body (10) and the lower valve seat (8) which are designed as pressure pieces (14, 16) yielding differently to the closing force.
