31705-X132B

1. Precise Adaptation to Specific Vehicle Models, OEM-Level Compatibility

As an exclusive control component for the transmission of specific vehicle models, the 31705-X132B transmission valve body is developed in strict accordance with the technical standards and dimensional parameters of the corresponding original equipment manufacturer (OEM). The oil passage diameter of the valve plate and the spool stroke are perfectly matched with the hydraulic system of the original vehicle's transmission, and the interface specifications achieve seamless connection with the Transmission Control Unit (TCU). It can be directly installed without additional cutting or modification, effectively avoiding problems such as oil passage misalignment and signal transmission delay that are common in non-adaptive valve bodies. This ensures that the transmission regains the original OEM power transmission efficiency, and is particularly suitable for scenarios such as replacing old valve bodies or troubleshooting repairs of the specific vehicle model. No repeated debugging is required after installation for normal operation.

2. Efficient Hydraulic Regulation, Balancing Shifting Response and Smoothness

Adopting a multi-oil-circuit independent partition control design, it is equipped with 12 sets of high-precision solenoid valves and pressure feedback valves, which can real-time capture dynamic parameters such as engine speed, vehicle speed, and throttle opening, and quickly adjust the pressure (with a regulation accuracy of ±0.2MPa) and flow rate of hydraulic oil. Compared with ordinary valve bodies, the shifting response speed is increased by more than 30%, and it can complete gear shifting within 80-180 milliseconds, significantly reducing low-speed shifting jitter. At the same time, through linear oil pressure regulation technology, it optimizes the engagement and disengagement process of clutches/brake bands to avoid power interruption. Whether it is frequent start-stop in urban congested road conditions or stable driving during high-speed cruising, it can maintain a smooth driving experience, suitable for multi-scenario usage needs such as household and commercial purposes.

3. High-Durability Materials and Precision Craftsmanship, Extending Service Life

The core valve plate is made of high-strength ADC12 die-cast aluminum alloy, which undergoes low-temperature aging treatment (aging temperature of 120℃, heat preservation for 8 hours) and surface nitriding process (nitriding layer thickness of 5-8μm). Its hardness is increased to over HV800, enabling it to withstand high-frequency oil pressure impacts (maximum pressure resistance of 35MPa) during transmission operation, effectively resisting valve body deformation and cracking. The internal spool uses SUS304 stainless steel substrate with polytetrafluoroethylene (PTFE) coating, reducing the friction coefficient by 40%, which minimizes wear and tear during long-term use and avoids spool jamming failures. The sealing components are made of hydrogenated nitrile butadiene rubber (HNBR) that is oil-resistant, high-temperature-resistant, and low-temperature-resistant (-40℃~150℃), with a compression set rate of less than 15%, eliminating the risk of transmission oil leakage. According to third-party testing, the service life of this valve body is 50% longer than that of ordinary similar products, making it suitable for harsh scenarios such as complex road conditions and high-frequency use.
