Description
Product Overview
The hydraulic proportional solenoid valve receives the electrical control signals from the equipment, drives the valve core through electromagnetism to precisely adjust the cross-sectional area of the hydraulic oil flow, and controls the speed and output pressure of the hydraulic cylinder/motor. After long-term exposure to dust and impurities in the construction site, the valve core may wear out, the coil may age, and the seal may leak, resulting in sluggish operation, uncontrolled flow, and equipment alarm limit actions. This product is a complete electromagnetic valve assembly, which has undergone a complete set of tests for valve core smoothness, coil conductivity, and oil pressure sealing at the factory. The entire machine can be replaced without disassembling the hydraulic valve block, and it is suitable for the maintenance of excavators, loaders, construction machinery hydraulic main control systems.
Unique Core Features of the Single Product
24V black integrated plastic-sealed solenoid housing, waterproof, anti-interference, and heat-resistant
Overall black epoxy resin sealed solenoid coil, with internal winding insulation protection, preventing erosion by hydraulic oil, rainwater, and dust. The coil is less likely to short-circuit and burn out in the high-temperature environment of the engine compartment, and the electrical control signal is resistant to electromagnetic interference, with stable and no-delay operation response.
Multi-oil channel stepped precision metal valve core, with linear and smooth flow adjustment
Front end alloy steel stepped valve core, with multiple circular oil flow channels evenly distributing hydraulic oil, mirror-polished surface of the valve core, precise fit, linear and smooth oil pressure adjustment, eliminating operation jolts and imbalance issues; resistant to wear and impurity erosion, less likely to get stuck.
Golden wear-resistant metal gasket, double sealing to prevent internal leakage
The middle section of the valve core is equipped with an integrated golden wear-resistant gasket, separating the high and low pressure oil chambers, reducing internal hydraulic oil leakage and pressure loss, ensuring stable hydraulic system pressure and extending the valve core service life.
Side-mounted waterproof electrical control connector, convenient to install and remove without false connection
The standard side-mounted electrical control connector on the valve body is equipped with multiple layers of waterproof and dustproof rubber rings. The pins are less likely to oxidize and loosen under jarring working conditions. The 24V power supply is compatible with mainstream construction machinery electrical control systems, and the insertion and removal are simple.
Adjustable locking screw at the tail, allowing for fine adjustment of hydraulic output parameters as needed
The end of the valve body is equipped with a regulating screw + locking nut, allowing for fine adjustment of the valve core stroke during maintenance, suitable for different working conditions and hydraulic flow and pressure requirements, and locking and fixing after adjustment to avoid long-term vibration-induced parameter deviation.
Application Scenarios
Suitable for small and medium-sized excavators, wheeled loaders, mining loaders, fixed hydraulic test equipment, and suitable for 24-hour continuous heavy-duty, high-dust, high-temperature, and low-temperature construction machinery hydraulic main control systems maintenance.
