III. Structural design and performance advantages

1. Stainless steel shell: a protective barrier for harsh working conditions

Made of 304 stainless steel in one piece by stamping, compared with ordinary carbon steel shells, it has three core protective advantages:

Strong corrosion resistance: Effectively resists the corrosion of rainwater, road salt, dust, etc., and is suitable for harsh environments with high dust and humidity such as mines, coastlines, and infrastructure. The shell has a rust-free service life of ≥5 years;

Excellent vibration resistance: The tensile strength reaches 520MPa or more, which can withstand the high-frequency vibration of heavy truck driving (vibration frequency 10-2000Hz, acceleration 20g), no risk of deformation or cracking;

Wide environmental adaptability: Outstanding high and low temperature resistance, can work stably in ambient temperatures of -40℃ to 85℃, avoiding shell embrittlement or seal failure caused by extreme climates.

2. Built-in high-quality electromagnetic coil: efficient and reliable power core

Equipped with a fixed-state...The high-efficiency electromagnetic coil is made of oxygen-free copper enameled wire and features an optimized magnetic circuit design, achieving three major performance breakthroughs:

Fast response speed: The coil's rated power is ≤35W, and magnetic force is generated instantaneously after energization, with a valve core action response time of ≤50ms, ensuring rapid start-up of the pneumatic device;

High operational reliability: The coil's insulation class reaches H, with a temperature resistance of ≥180℃, and it can withstand 1000 hours of continuous operation without overheating damage. Its operational life is ≥1 million cycles, far exceeding the industry average;

Optimized energy consumption: It adopts a low-power design, with a standby current of ≤5mA and a stable operating current of 2.8-3.2A, reducing the overall vehicle power consumption while meeting control requirements.

3. Standard wiring harness plug: A practical design for convenient installation

Equipped with ISO 6409 compliant..." Standard waterproof wire harness connector, balancing installation efficiency and reliability:

Easy installation: The connector uses a snap-fit ​​connection design with moderate insertion and extraction force (insertion force ≤30N, extraction force ≥15N), allowing for assembly without professional tools, suitable for original equipment manufacturer (OEM) assembly and after-sales service scenarios;
