VANASAN Cast & Forged Steel Valves
Theese types of valves are used to regulate or to throttle the flow.
Flow control in these valves can be made by small increments.
Pressure drop obtained by throttling should not go over %20 because it can lead to noisy vibrations consequently to mechanical failures in the valve and piping system.
