Product Description:

Parker relief valve features include precise pressure control, high reliability, multiple types, easy maintenance and wide application. Parker relief valves can accurately control the pressure in the hydraulic system and keep the system running stably. High-quality materials and advanced manufacturing processes are used to ensure that the relief valve can provide reliable performance even under harsh working conditions. Parker offers a variety of relief valves, including direct-acting relief valves and pilot-operated relief valves, to meet the needs of different applications. The design takes into account the convenience of users, making the relief valve easy to install, debug and maintain. Parker relief valves are suitable for various hydraulic systems, such as industrial machinery, mobile equipment, aerospace, etc.

When using Parker relief valves, the following points need to be noted:

Media characteristics: Select the appropriate solenoid valve according to the properties of the medium (such as gas, liquid or mixed state). For example, ZQDF is used for air, ZQDF-Y is used for liquid, and ZQDF-2 is used for steam. Medium temperature and viscosity are also important parameters for selection, and high-viscosity media require special orders.

Pipeline parameters: Select the valve port and model according to the flow direction requirements of the medium and the pipeline connection method. For example, ZDF-Z1/2 is suitable for switching from one pipeline to two pipelines, and ZDF-Z2/1 is suitable for the confluence of two pipelines.

‌Pneumatic control valve‌: Pneumatic control valves are divided into two categories: air-open and air-close. The air-open control valve is closed in a fault state, and the air-close control valve is open in a fault state. Some auxiliary equipment can be used to form a position-holding valve or make the control valve self-locking.

‌Remote control pressure regulation‌: The front chamber of the overflow valve has a remote control port, which is connected to a remote control pressure regulating valve and a solenoid valve to return to the oil tank for unloading. The remote control pressure regulating valve plays the role of remote pressure regulation.

‌Safety protection‌: The overflow valve is closed when the system is working normally, and is opened when the load exceeds the specified pressure to perform overload protection so that the system pressure no longer increases.
