摘要

#CMT# #/CMT# Hydraulic or pneumatic seat valve (2) comprises a valve seat (10) formed in a base part (4) and interacting with the sealing surface of a valve body (8) mounted in a hood part (6). The base part and the hood part are interconnected. The base part has an at least partly peripheral collar (18) facing radially outward with which the seat valve is fixed on a further component, especially on a housing by a weld connection. #CMT# : #/CMT# An independent claim is also included for an arrangement comprising the above seat valve. Preferred Features: The collar has an enlarged area (22) for the weld connection. #CMT#USE : #/CMT# Used as a pressure relief valve. #CMT#ADVANTAGE : #/CMT# The valve is easy to assemble. Long-lasting accurate positioning of the valve in a housing is achieved. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cross-section through the seat valve. 2 : seat valve 4 : base part 6 : hood part 8 : valve body 10 : valve seat 18 : collar 22 : enlarged area.
