How to determine the inlet and outlet directions of an eccentric control valve
Thread Content
A batch of control valves was purchased from abroad, including flow control valves, pressure control valves, and temperature control valves. The diagrams show different flow directions for the media; could you please advise on the main factors to consider when determining the flow direction of the media? Thank you!
As long as the pressure on the back side of the valve core does not affect the switch, the back side should be the side with the higher pressure. Entrance.
Could it be that the manufacturer marked it wrong? . .
Could you explain what direction it should be? Is it considering the wear of the sealing surface? Thank you!
Unless otherwise specified, gas flow is on and liquid flow is off. Liquid cavitation erosion and noise are the main considerations.
Under normal circumstances, use \"Flow On\" for adjustment, and use \"Flow Off\" for cutting off.
Installation direction of the eccentric rotary valve: For air shut-off valves, it should be installed in the flow-blocking direction; for air flow-through valves, it should be installed in the flow-allowing direction. This is the correct answer! If seal surface repair is necessary due to erosion wear, a flow-blocking installation should be adopted; in practical applications, the installation direction can be chosen flexibly based on the operating conditions.
