GVO Background

  Guangzhou GVO Precision Hydraulic Co., Ltd. is a professional manufacturer and exporter of precision hydraulic components and electrical systems for excavators. We are headquartered in Guangzhou, China, and we have been serving the global construction machinery industry since 2017.

  We are a team of engineers, technicians, and industry professionals who understand the demands of heavy equipment operation. We are not a trading company. We are not a reseller. We are a manufacturer — and that makes all the difference.

  GVO was founded by a group of engineers and hydraulic industry professionals with decades of combined experience. They had spent years working with excavators, understanding how hydraulic systems operated, and seeing firsthand what happened when parts failed.They saw a clear challenge: the market was vast, yet customers consistently faced inconsistent quality, mismatched components, long delivery times, and unclear pricing. Customers were spending too much time chasing orders, verifying compatibility, and dealing with unexpected costs.They decided to build a better way. They built GVO to prove that quality parts could be accessible, reliable, and delivered without unnecessary delays.In the beginning, we were small. A modest workshop. A handful of products. A commitment to getting every order right. We spent the first two years refining our processes, testing our products, and building relationships with customers who valued quality and reliability. We did not try to grow fast. We focused on growing right.

GVO. Built to keep you working.
