Product Description


SINOTRUK Truck Air Suspension System Parts SITRAK C7 T5G Seat Height Valve Assembly WG1662512139 



The WG1662512139 Seat Height Valve Assembly is a pneumatic control component installed in the air-suspended driver's seat. It regulates the air supply and exhaust of the seat air spring, allowing the seat suspension to maintain the selected riding height. The valve works with the seat air spring and mechanical linkage. When the seat height changes because of driver weight or road movement, the valve can control the air entering or leaving the air spring so that the seat returns toward its designed operating height. This makes it an important component for maintaining a stable seating position. Unlike a conventional mechanical seat adjustment lever, this valve controls the pneumatic suspension circuit of the truck seat. It works together with the airbag, shock absorber, seat frame, and related pneumatic components to provide vertical suspension movement and height adjustment. For long-distance heavy truck operation, the air-suspended seat needs to accommodate different driver weights and changing road conditions. The height valve helps regulate the air spring and maintain the working height of the seat suspension, contributing to a more consistent driving position.

اشتريتُ قبل ثلاثة أسابيع حشوات زيت متينة لشاحنات أسطولي من شركة HOWO من هذا المتجر المستقل. بصفتي مدير أسطول أدير 22 شاحنة نقل بضائع في لاغوس، كنتُ بحاجة إلى حشوات مطاطية متينة تتحمل درجات الحرارة العالية على الطرق الأفريقية الوعرة. كل حشوة تناسب تمامًا دون أي تسريب للزيت أثناء النقل لمسافات طويلة. استغرقت الشحنة إلى ميناء لاغوس 8 أيام فقط، وكان فريق المبيعات سريع الاستجابة عندما طلبتُ أسعار الجملة.
