Introduction

As industrial automation accelerates, the reliability, precision and safety of fluid control equipment directly affect continuous production and consistent end-product quality. Where does customer trust come from? For HES, the answer is not marketing language but thirty-odd years of technical accumulation, supply integration, service response and quality records. Here are six supporting pillars.

1. Thirty Years: From the First Domestic Actuator to Twin Bases

The company's growth has run in step with China's industrial automation: from the founder entering fluid control in 1989, to the launch of the first domestic pneumatic actuator in 1997, to today's twin-base operation across Wenzhou and Shanghai. Over more than three decades the company has accumulated more than twenty national patents, and the product range has evolved from the first-generation QGH series to the AT, AW and HG series - witnessing and taking part in the shift from imported piping control to self-reliant capability.

2. Three Key Technical Improvements Aimed at Real Duty Conditions

Every upgrade targets a genuine pain point in the field:

  • For severe corrosive duty, a hard-anodized aluminium alloy cylinder process improves durability in corrosive environments

  • For high-frequency cycling, the rack-and-pinion drive structure is optimized for steadier action and longer life

  • For high-torque applications, the scotch yoke actuator series is designed for large-diameter, heavy-load valves

These improvements do more than raise the performance of a single unit - they also help advance industry technical standards.

3. Integrated Supply: Taking Complexity Out of Selection and Commissioning

For years, industrial projects sourced actuators and valves from different suppliers, which caused difficult commissioning and poor matching on site for a great many end users. HES was among the first to build an integrated actuator-valve-accessory development and production system: from pneumatic actuators to pneumatic butterfly valves, ball valves and control valves, and on to solenoid valves, limit switches and filter regulators - the whole chain manufactured in-house and supplied as a system.

The range behind that capability is broad: more than 100 series and models, actuator output torque from 8 to 6000 N·m, suited to valves from DN15 to DN800, covering the varied needs of different industrial duties.

4. Delivery and Service: Full-Cycle Response from Selection to Spare Parts

  • Up front: free duty assessment and selection support, helping customers avoid losses caused by poor selection

  • Supply: standard models delivered in 7-15 days, custom models scheduled to order, shortening the project cycle

  • After sales: on-site technical guidance, troubleshooting and fast spare parts supply, cutting maintenance cost and downtime risk

There are concrete results too: in wastewater treatment projects the equipment helped customers reduce later maintenance costs by about 30%, and in a sheet metal and metallurgy plant piping automation retrofit, high-torque scotch yoke actuators replaced imported equipment and halved the supply lead time.

5. Quality and Certification: Behind a Reject Rate Under 2%

The product reject rate is below 2%, a record supported by certifications and control systems: ISO9001 quality management, CE certification, special equipment manufacturing licence and more, plus full process quality control from raw material intake to finished goods dispatch. For industrial users these are not paper credentials but the foundation of equipment that causes fewer problems on the line.

6. Market Feedback: Multi-Industry Verification and Export Performance

Across chemicals, environmental protection, metallurgy, oil and gas and power, HES products have withstood long-term testing in complex duty: customer feedback centres on "stable operation under high temperature and high pressure", "prompt after-sales response", "on-time delivery", "complete certification" and "years of service without problems" - which in turn drives repeat orders and active referrals.

In application terms, the sedimentation tanks and dosing lines of municipal wastewater projects, and RTO waste gas treatment in chemical plants, are places where complete actuator and valve packages are running - reliable fluid control also serves the green transition. Overseas, products have been exported to more than ten countries including Russia and Southeast Asia, competing internationally with reliable quality and a competitive price-performance ratio.

Conclusion

Serving industrial automation with reliable domestic fluid control equipment - that has been the HES position for over thirty years. From technical iteration to integrated supply, from delivery response to quality records, customer trust ultimately comes from how the equipment performs on the line. If you are planning a piping automation retrofit or a new project, send the duty parameters and valve requirements to the HES technical team for selection support and complete supply advice.
