3515010022 Directional Valve Plug for S1800-1/S2100 Asphalt Paver

Product Introduction：

The directional valve plug for the paver features a military-grade composite engineering plastic housing. The internal copper alloy contacts are gold-plated to ensure low-impedance conduction, and an integrated spring lock mechanism ensures a zero-loose connection even under vibration. The multi-pin design with color-coded rings distinguishes signal types, and a built-in magnetic filter suppresses electromagnetic interference from the hydraulic system. The mating surface meets IP67 protection standards and is equipped with a silicone seal to effectively resist corrosion from asphalt vapor and dust. A strain relief sleeve is installed at the cable outlet to prevent bending damage. The flame-retardant material meets the safety requirements of high-temperature environments for construction machinery and supports quick plug-in and disconnection maintenance without affecting control system stability.

What are the specific advantages of gold-plated contacts over ordinary copper contacts?

The gold plating effectively inhibits oxidation of the copper substrate, maintaining long-term stable contact impedance, making it particularly suitable for the high-humidity environment of paver hydraulic systems. The gold surface has a low coefficient of friction, reducing mechanical wear during insertion and removal. Combined with the elastic contact finger structure, it achieves a plug-in/plug-out lifespan of over 5,000 cycles. Its excellent conductivity reduces signal transmission loss, ensuring the waveform integrity of the PWM control signal while preventing contact failure caused by electrochemical corrosion, significantly improving the control accuracy and response speed of the directional valve.

How is the plug secured against loosening under vibrating conditions?

A dual-locking mechanism is employed: the primary lock is a stainless steel spring clip providing continuous clamping force, while the secondary lock is reinforced by a screw-on housing thread. The internal contacts feature a floating design, allowing ±2mm axial displacement to compensate for vibration offset. The cable is braided with Kevlar tensile fiber, and the connection to the connector is injected with polyurethane cushioning adhesive to create a vibration energy-absorbing structure. The special wedge-shaped sealing ring will produce a self-tightening effect after expanding under pressure. The greater the vibration intensity, the more significant the sealing and anti-loosening effect.
