Control valves (control valves) is a tool to control the fluid pressure, the direction of fluid flow, average flow rate and velocity of fluid flow.<\/span><\/span><\/p>\n Balanced piston type relief valve<\/strong> If the actuator is affected by the load and the oil pressure in the A, then change the oil pressure pilot valve to the right after passing through a choke to the section B. When the oil pressure exceeds spring pressure pilot, the pilot valve will open and allow the oil to flow through the A and b continue to C to D and E. If the load increases again, then the choke which is housed in the A and B be lifted, causing a pressure difference between A and B. If this pressure difference exceeds the style of play spool spring, the main spool will go up, and The main valve seat will be open, and let the high pressure oil flows into the tank circuit E. Then, prevented the increase in pressure A.<\/p><\/div>\n Pressure Reducing Valves<\/strong> Valve series<\/strong>\n
\nThe main spool is pressed against the main valve seat along with the initial pressure of the construction by using the main spool spring. Pilot valve is pressed against the valve seat pilot through the pilot spring, the pressure can be set via the handle.<\/p>\n

\nThis valve is used to reduce the pressure in a series of more than uatama circuit. This is normally called the valve is open.<\/div>\n

\nThese valves are used to control the function of the hydraulic actuator series with the circuit pressure. This valve is constructed together with valve reliefs but has a spring chamber which flowed separately into the reservoir. This valve also has an integral check valve backflow. This valve is a normally closed valve.<\/div>\n
