Cam operated valve is a cam operated valve.
the term | Explanation | the term | Explanation |
Control valve | General term for valves that change the flow state and control the pressure or flow | Solenoid operated valve | Solenoid operated valve |
Pressure control valve | Generic term for valves that control pressure | Manually operated valve | With manually operated valve |
Flow control valve | Generic name for valves that control flow | Cam operated valve | Cam-operated valve |
Directional control valve | Generic term for valves that control the direction of flow | Pilot valve | Auxiliary valves used to operate control mechanisms in other valves or components |
Sequence valve | In a system with two or more branch circuits, a valve that controls the sequence of operation of the actuator according to the pressure of the circuit, etc. | Hydraulic directional valve | Directional valve operated with pilot fluid pressure |
Balancing valve | Pressure control valve to maintain back pressure to prevent load drop | Pilot operated check valve | A valve that allows a non-return valve to flow by controlling the pressure of the fluid |
Pressure reducing valve | The outlet pressure of this pressure control valve can be adjusted to a value lower than the inlet pressure, this value has nothing to do with the flow rate and the inlet side pressure | Two-position valve | Reversing valve with two valve positions |
Unloading valve | Valve capable of unloading hydraulic pump under certain conditions | Electro-hydraulic directional valve | Hydraulic directional valve combined with electromagnetically operated pilot valve |
Throttle | A valve that uses a throttling action to limit the flow of liquid. Usually refers to a flow valve without pressure compensation | Valve position | The position used to determine the flow state in the reversing valve |
Control Valve | Flow control valve that is independent of back pressure or pressure change due to load and can maintain the flow set value | Normal position | Valve position when no operating force is applied |
Speed compensation valve with temperature compensation | Speed regulating valve that can be independent of liquid temperature and can maintain flow setpoint | Neutral position | Determined central position of the reversing valve |
Diverter valve | When diverting fluid to more than two hydraulic pipelines, the application of this valve allows the flow to be split in a certain proportion, regardless of the pressure in each pipeline. | Offset position | All valve positions except the neutral position in the reversing valve |
Directional valve | Directional control valve with two or more flow patterns and two or more ports | Locked position | Valve position of the directional valve held by the locking device |
Cover (or overlap) | The overlap between the valve spool shoulder portion and the window portion of the spool valve, the value is called the covering amount | Three-position valve | Reversing valve with three valve positions |
Relief valve | When the pressure of the circuit reaches the set value of such a valve, a part or all of the fluid flows back to the tank through this valve, so that the pressure of the circuit is maintained at the set value of the valve | Two-way valve | Control valve with two ports |
Safety valve | Valve to limit the highest pressure in the circuit to prevent damage to components, pipes, etc. | Four-way valve | Control valve with four ports |
Zero cover | When the spool of the spool valve is in the neutral position, the window is completely closed, and when the spool is slightly displaced, the window opens and the liquid can pass through. | Spring return valve | Valve returned to normal position by spring force |
Covering | When the spool of the spool valve is in the neutral position, there must be a certain amount of displacement (not large) before the window can be opened | Median closed | All ports are closed when the directional valve is in the neutral position |
Negative cover | When the spool of the spool valve is in the neutral position, there is already a certain amount of opening | Median open | All ports are connected when the selector valve is in the neutral position |
servo valve | Control flow or pressure as a function of an electrical signal (or other input signal) | Normally open | The pressure port is connected to the oil outlet in the normal position |
Spool valve (or spool valve) | Valve with cylindrical spool valve | Normally closed | Pressure port is closed in normal position |
Shuttle valve | Valve with one outlet and two or more inlets, the outlet having the function of selecting the inlet with the highest pressure | Spring centering valve | Three-position directional valve with normal position in neutral position, which belongs to a type of spring return valve |
The electromagnetic valve | This is the collective name of solenoid operated valve and solenoid piloted directional valve. | Spring biased valve | Reversing valve whose normal position is offset position belongs to a type of spring return valve |
Check valve | The fluid can only flow in one direction and cannot pass in the other direction | Number of ports | Number of ports connected to the valve |
Throttle Reversing Valve | Reversing valve whose flow rate can be continuously changed according to the operating position of the valve | Shoulder section | Sliding surface of spool when moving |
