Parker MVI series globe and throttle valveParker MVI series globe and throttle valves: The steel valve body needle valve can be installed on the valve block in the form of a threaded plug-in valve. The valve core can choose from a 30 degree conical surface, V-shaped cut, or rectangular cut. The shape of the throttle affects the accuracy of flow regulation, which is related to pressure and viscosity. The needle shaped valve core is made of stainless steel and forms a circular gap inside the valve cylinder. The forming tool for machining the valve block hole is detailed in the instructions. |
 |
Parker FS series one-way throttle valveThe Parker FS series one-way throttle valve can regulate flow in a specified direction. The oil overcomes minimal flow resistance and flows through the installed one-way valve in the opposite direction. The two-stage needle valve can accurately adjust small flow rates in the first 3 turns of the adjustment knob. The last three valves have all been opened. The adjustment result of the valve can be locked by positioning the bolt. |
 |
Parker NS series globe and throttle valveThe first three turns of the adjustment knob for the needle valve of the Parker NS series globe and throttle valve with a two-stage needle cone surface are the first stage, which can sensitively adjust the flow rate. The last three circles are the second stage, which has ordinary throttling characteristics. To reduce the influence of viscosity, cylindrical needle valves with rectangular notches can be used for valves with structural dimensions of 400 and 600. Flow rate is related to pressure and viscosity. |

Parker F-series one-way throttle valveThe Parker F-series one-way throttle valve can regulate flow in a specified direction. The oil overcomes minimal flow resistance and flows through the installed one-way valve in the opposite direction. The two-stage needle valve can accurately adjust small flow rates in the first 3 turns of the adjustment knob. The last three valves have all been opened. The adjustment result of the valve can be locked by positioning the bolt. |
 |
Parker 6F series one-way throttle valveThe Parker 6F series one-way throttle valve has metric connection threads. The flow rate can be sensitively adjusted in the specified flow direction. In the opposite direction to the throttling effect, the oil can freely flow through the one-way valve of the bypass. |
 |
Parker N series globe and throttle valveParker N series globe and throttle valve: The first stage is the first stage of the adjustment knob of the two-stage needle cone globe and throttle valve, which can sensitively adjust the flow rate. The last three circles are the second stage, which has ordinary throttling characteristics. To reduce the influence of viscosity, cylindrical needle valves with rectangular notches can be used for valves with structural dimensions ranging from 200 to 600. Flow rate is related to pressure and viscosity. |

Parker 6N series globe and throttle valveThe Parker 6N series globe and throttle valve Manatrol valve has metric connection threads. There are different needle shaped valve cores available for use, which can accurately adjust the flow rate. The advantages include: the connection method complies with the ISO6149 standard, and it has a conical contact surface for O-rings; Metric connection thread; The O-ring seal can effectively prevent leakage between threaded fittings and connecting threads; Can be replaced worldwide. |
 |
Parker MV series globe and throttle valveThe Parker MV series globe and throttle valve needle valve can choose a valve core with a 30 degree conical surface, V-shaped notch, or rectangular notch. The shape of the throttle affects the accuracy of flow regulation, which is related to pressure and viscosity. The needle shaped valve core is made of stainless steel and forms an annular gap inside the valve cylinder. You can choose steel or brass valve bodies, as well as pipe or panel installations. |

Parker TDA series proportional throttle valveThe Parker TDA series proportional throttle valve consists of three stages. The valve cone is pilot controlled by the servo spool of the seat valve structure. Proportional solenoid valve with force feedback adjusts the position of the servo spool. Therefore, the position of the valve cone will not be affected by the pressure difference. The pressure difference can reach the maximum working pressure. The control oil flow rate of the pilot control is approximately 1 l/min. The minimum working pressure is 3 bar. The control pressure must be greater than 25% of the system pressure at port A. The accuracy of flow regulation is 0.5%. Due to the asymptotic nature of the flow characteristic curve, the adjustment accuracy is improved to 0.25% in the asymptotic region when the flow is small. The adjustment time for the entire stroke is approximately 25ms. When the oil flows from B to A, there should be no leakage from B to A in the closed initial position. At this initial position, pilot control does not require control oil. The pressure at the return port T cannot exceed 100 bar. |

Parker GFG Series 2-way Speed Control ValveParker GFG series two-way speed control valve: In hydraulic systems, two-way speed control valves are flow control components. The regulated flow rate is independent of fluctuations in pressure, temperature, and viscosity. The external control oil port P on the component structure can avoid instantaneous oil shock (starting jump) when the oil circuit is connected. Structure: The two-way speed regulating valve is composed of a triangular orifice and a constant differential pressure reducing valve. The adjusted flow value can be locked by a cylinder pin lock on the knob to prevent accidental changes. |

Parker PCMS Series 2-way Speed Control ValveParker PCMS Series 2-way Speed Control Valve: Used for regulating pressure compensation of flow. As a result of pressure changes, the adjusted value can vary within a tolerance range of ± 5%. Of course, changes in viscosity can also have an impact and must be taken into account. |
 |
Parker PCM Series 2-way Speed Control ValveParker PCM series 2-way speed regulating valve: used for pressure compensation adjustment of flow. As a result of pressure changes, the adjusted value can vary within a tolerance range of ± 5%. Of course, changes in viscosity can also have an impact and must be taken into account. |

Parker DUR * L06 Series 2-way Proportional Speed Control ValveParker DUR * L06 Series 2-way Proportional Speed Control Valve: The DUR * L06 series proportional speed control valve can be used to electrically remotely adjust the speed of hydraulic actuators (hydraulic cylinders, hydraulic motors). The pressure of the installed compensator can make the flow independent of the load (load sensing). By using a pressure compensator, temperature independence can be further ensured. If the valve is equipped with a displacement feedback device, electrical monitoring and position adjustment should be carried out for measuring the displacement of the valve core and the opening of the pressure compensator. This can improve lag and repeatability accuracy. Oil can flow through the one-way valve in the opposite direction. If it is necessary to ensure that the flow into and out of the actuator (such as a differential hydraulic cylinder) is independent of the load pressure, a rectifier intermediate plate can be used to ensure that the oil flow always flows through the working direction of the speed control valve (from A to B). |
