Pressure-Compensated Valves
Pressure-compensated flow-control valvesovercome the difficulty causedby non-pressure-compensated valves by changing the size of the orifice in relation to the changes in the system pressure. This is accomplished through a spring-loaded compensator spool that reduces the size of the orifice when … Continue reading
Non-Pressure-Compensated Valves
Non-pressure-compensated flow-control valves are used when the system pressure is relatively constant and motoring speeds are not too critical. The operating principle behind these valves is that the flow through an orifice remains constant if the pressure drop across it … Continue reading
Pilot Operated Flow Control and Check Valves
These valves are pilot-operated. They control the flow with a hydraulic cylinder to accelerate or decelerate the actuator without shock. Other flow control valves described below are available • Flow Control and Relief Valves These valves contain a flow control … Continue reading
Yuken Feed Control Valve Released in 1965
Features 1. Provides seamless feeding speed control in two modes (regardless of the cutting resistance and the fluid temperature) 2. Very compact, compared to previous feed control valves. 3. Can be easily mounted/demounted with gaskets. 4. Allows direction switching to … Continue reading
Feed Control Valves
These valves are a combination of a flow control and check valve and a deceleration valve; they are used mainly for feed control of machine tools. Switching from rapid traverse to feed is made by a cam operation, and the … Continue reading
Deceleration Valves/Deceleration and Check Valves
These valves continuously regulate flow rates, using a cam mechanism. Pushing the spool down decreases the flow rate for the normal open type and increases it for the normal close type. When the normal open type is installed to cushion … Continue reading
Flow Control Valves/Flow Control and Check Valves
These valves consist of a pressure compensator (pressure reducing valve that keeps the pressure difference constant) and a restrictor. They maintain a constant flow rate, independent of the inlet-outlet differential pressure. Provided with a sharp-edge orifice, they can also work … Continue reading
Yuken Restrictors/One Way Restrictors
These valves regulate flow rates in hydraulic circuits. They have the advantages of plain structure, simple operation, and wide range of adjustment. On the other hand, they cannot accurately control the flow; even through the fixed restriction, the flow varies … Continue reading
Gear-Type Flow Divider Valve
The gear-type flow divider valve works like two hydraulic gear motors with attached shafts. The both motor must have to run at the same speed since their shafts are attached. Thus, the same flow goes through both sides. The flow … Continue reading
Hydraulic Flow Control Valves
A hydraulic flow control valve is a device used for adjusting or manipulating the hydraulic oil flow rate. The hydraulic flow control valve constructs of a flow passage or a port whose flow area can be varied. Most common applications … Continue reading
