Product Name: 160 MPa Stainless Steel High Pressure Pressure Relief Valve Model NO.: LYHR Material: Stainless Steel Structure: Spring Closed: Open Pressure: Adjustable Connection: Thread Temperature: -40 Celsius-80celsius Certification: CCC, RoHS, ISO, CE Media: Water/Oil/Other Media Work Pressure: 160MPa,23200psi Trademark: LOYO Transport Package: Wooden Box Origin: Guangzhou China HS Code: 8481400000 Product Description High pressure relief valve As a manufacturer of pressure test pumps in Guangzhou, LOYO hydraulics has more than 10 years of R&D experience and engineers are dedicated to creating products that are professional and satisfying customers. Excellent quality and excellent interactivity. The relief valve is a hydraulic pressure control valve, which mainly plays the role of constant pressure overflow, voltage regulation, system unloading and safety protection in hydraulic equipment. Use the pressure adjustment of the spring and the pressure. When the pressure is lower than the working pressure, the valve core is pressed by the spring at the inflow port. When the pressure of the hydraulic oil exceeds the working allowable pressure, that is, greater than the spring pressure, the valve core is pushed up by the pressure, the pressure flows in, and flows out from the side port. Large, the valve core is pushed up by the pressure, the pressure is less than or equal to the spring pressure, then the spool falls and seals the pressure inlet.Features Use medium temperature: -40 ° C to 80 ° C;The highest pressure can reach 160MPa (23200PSI); please consultMade of stainless steel corrosion resistant material for use in clean water, oil or other media.Product Usage1. Constant pressure overflow: In the quantitative pump throttle regulation system, the fixed pump provides a constant flow. When the system pressure increases, the flow demand is reduced. At this point, the relief valve opens, allowing excess flow to overflow back to the tank, ensuring the inlet pressure of the relief valve, ie the pump outlet pressure is constant (the valve port often opens with pressure fluctuations).2. Regulating effect: The relief valve is connected in series on the oil returning road, the relief valve generates back pressure, and the smoothness of the moving parts increases.3. System unloading function: The solenoid valve of the small flow is connected in the remote control port of the overflow valve. When the electromagnet is energized, the remote control port of the overflow valve passes through the fuel tank, and the hydraulic pump is unloaded at this time. The relief valve is now used as an unloading valve.4. Safety protection: When the system is working normally, the valve is closed. only when the load exceeds the specified limit (system pressure exceeds the set pressure), the overflow is turned on, and the overload protection is performed, so that the system pressure is no longer increased (usually the set pressure of the relief valve is 10% to 20% higher than the maximum working pressure of the system). ).
