A valve, particularly for smaller sizes, with minimized envelope size and dead volume. Its body is comprised of two seamless parts, one inserted into the other and welded together with a single weld. This weld is the only joinder of the two parts. The inserted part has a valve seat and a free end which is cantilevered freely into the other part so the free end does not contact the other part. Closure means and actuator means are provided to control the valve.
