Introduzione della valvola dell'aria
Needle valve
Mini hydraulic press valves needle valve has the advantages of simple structure and low cost. The needle valve is a trim valve with a needle plug that is primarily used to regulate airflow. The needle valve has the advantages of simple structure and low cost.
Gap plug valve
Mini hydraulic press valves gap plug valve has a short narrow flow path, which means that its action is virtually independent of the viscosity of the working fluid. The gap plug valve can be precisely adjusted, but the manufacturing cost is high.
Adjustable choke valve
The illustration shows the actual adjustable choke valve.
Adjustable unidirectional choke valve
Mini hydraulic press valves adjustable unidirectional choke valve is composed of an adjustable choke valve and a unidirectional valve. In the illustrated unidirectional choke closing direction (from port A to port B), the working fluid flows out through the adjustable choke valve.
Adjustable unidirectional choke valve can be used with relief valves or variable displacement pumps to change speed.
In the opposite direction (from port B to port A), there is no throttling, ie the working fluid can flow freely.
Speed control valve
The speed control valve provides a constant flow rate independent of changes in its inlet and outlet pressure. The illustration shows that the speed control valve is in the rest position.
