Disc valve control head - is mounted on valve housing via spacer with inspection holes

摘要

The disc valve control head is set on the valve housing via a spacer fitted with inspection holes and is joined to the valve rod. The spacer (18) flanged onto the base (212) of the control head (2) is integrated with a cover (16) fixed to the valve housing (1). The vale rod (141) projecting (142) above the control head and led through this is guided in the hollow shaft (221) of the control piston (22). The shaft bearing on the valve side on a ring shoulder (143) of the valve rod is loaded by a nut (144) as screwed onto the projecting part of the valve rod. ADVANTAGE - Valve rod and piston shaft designed for easy correct assembly using flanged spacer to accept different sized valves on a standard head.
