4.8 Function
Design The valves consist of a two-piece body 100 with threaded ends. The valves are
provided with an elastomer stem seal. The functional unit consists of valve disc 350,
stem 200 and handwheel 961.
Function The valves are equipped with two pressure measurement connection branches
131.1/.2 for measuring the flow rate. By combining the valve with a differential
pressure gauge, system-specific flow rates can be measured. Valve travel in opening
direction can be limited by setting travel stop 904 at the handwheel, so that the valve
cannot be opened beyond this position.
Depending on the flow rate to be set, the valves are opened or set to the required
valve plug position. As the valves are fitted with throttling plugs as standard, they
are suitable for both on/off and control duties.
Sealing The passage of stem 200 through body 100 is sealed by O-ring 412.1.
