[Major Announcement] Zero drift = 0, crushing the competition! Liquid Doctor has globally pioneered a hydraulic valve, dethroning a certain brand.
Release time:
2026-07-25
With the same six‑port design, it delivers a flow rate of 51.3 and costs less than one thousand yuan. Liquid Doctor has leveraged two national‑level reports to herald China’s hydraulics industry into the fully digital era.
Abstract
Also with six ports, the flow rate drops to 51.3, yet the price is less than… One thousand yuan . Dr. Liquid uses two portions National-Level Report , heralding the entry of Chinese hydraulics into The All-Digital Era 。
It’s time to revise the “foreign rules” governing hydraulic valves.
Part.1
Anyone in the high-end equipment industry knows: if you want precise control, in the past your only option was to go with imported solutions. The United States… A certain grid As the industry’s ceiling, it has dominated the high-end hydraulic valve market for many years. Yet its pain points are also those of the entire industry:
❌
It has temperature drift, and it has… Zero drift
It drifts over time and requires annual calibration.
❌
Complex wiring
It requires an external expansion board and external sensors, resulting in a bloated system.
❌
Extremely expensive
A single valve can easily cost tens of thousands, squeezing the profit margins of Chinese equipment ever thinner.
No knockoffs—just outright surpassing.
Recently, Yiatong (Zhejiang) Hydraulic Technology Co., Ltd. (under the Liquid Doctor brand) independently developed “ All-digital direct-drive high-precision self-sensing hydraulic valve ", officially obtained two major authoritative certifications:
National Testing Six‑channel flow rate—directly outperforms imported models.
As verified by the National Hydraulic Components Quality Inspection and Testing Center (Report No.: (2026) Liquid Inspection No. 03).
According to global searches conducted by the Zhejiang Provincial Institute of Scientific and Technical Information, a national first-class novelty‑search institution: our… All-digital direct-drive architecture, four-in-one integration, edge intelligence algorithms , which has not been reported in the global open literature and is classified as World’s first 。
Someone is still using it. Torque motor + Taking the “old-school” approach of springs, Liquid Doctor has simply switched to a whole new track:
🔢
All-digital direct drive
Abandon springs and analog signals; use digital pulse control. Ball screw , micron-level closed-loop control of the valve spool position, Naturally drift-free
🧩
All-in-one minimalism
Integrate the actuator, controller, sensor, and hydraulic valve body all into a single valve. No expansion board required, no sensor needed—just power it on and use it.
🧠
Built-in brain
Equipped with multi‑physical‑quantity sensing and intelligent algorithms, it features self‑diagnosis and predictive life‑time warning. Supports direct bus-to-cloud connectivity.
Others are mechanical parts; we are… Smart terminal
Unmatched performance, with a price that shatters all competition.
Part.2
Technology must be universally accessible to Made in China.
With core performance metrics such as six‑channel flow rate, zero drift, and hysteresis all matching or surpassing those of leading international brands—Model D633
