Origin of valve-engineering heritage
Continuing know-how develops around sealing, machining, flow topology, and actuation for analytical-instrument valves.
Company & capability / 01
Beijing Ruiketongheng Technology Development Co., Ltd. develops and manufactures precision valves, pressure-flow components, controllers, and integrated gas paths for analytical instruments, process analytics, and research systems. Engineering begins at a sealing interface and extends to the sequence and acceptance of a complete subsystem.


About us / 02
The product evolution reflected in the company materials draws on valve-engineering know-how dating to 1985. The date marks the start of the technical heritage; it is not presented as the legal incorporation year of Beijing Ruiketongheng Technology Development Co., Ltd.
Today the portfolio extends from electric, pneumatic, and manual switching valves into multi-stream selection, mechanical and electronic pressure-flow control, valve-bank controllers, heated modules, complete gas paths, and service hardware. This vertical range helps teams set the right delivery boundary between component and system.
Engineering path / 03
The timeline deliberately separates technical heritage, present company capability, and the international-site program so different dates are not conflated.
Continuing know-how develops around sealing, machining, flow topology, and actuation for analytical-instrument valves.
The portfolio spans precision switching, stream selection, pressure-flow, electronic control, thermal control, system integration, and service hardware.
rkth.net becomes the international domain, with bilingual product architecture, engineering boundaries, and email-based RFQs for cross-time-zone communication.
Capability map / 04
International projects can choose standard products, configured modules, gas-path subsystems, or OEM collaboration according to their own capabilities.
Valve architecture, sealing pairs, wetted materials, cavities, and actuation matching.
Processes organized around critical dimensions, cleanliness, assembly consistency, and functional records.
Actuators, controllers, communication, sensing, and heated modules coordinated together.
Turn process diagrams, operating conditions, and sequences into testable subsystems.
Quality & credentials / 05
The following information comes from the 2026 company materials. Before using it in tenders, audits, or contracts, confirm current certificates, official records, and mutually approved documentation.
Company materials list quality-management certification; scope and validity are subject to the current certificate.
The designation is listed in company materials; verify current official status before external use.
Safety-production standardization is listed in the materials; coverage is subject to valid documentation.
Company materials present multiple intellectual-property achievements; current status and applicable products require item-by-item confirmation.
Quality method / 06
From inquiry to delivery, requirements, drawings, materials, assembly, testing, and changes must remain linked.
Confirm conditions, regulation, interfaces, and acceptance scope.
Organize outputs through model, drawing, BOM, and revision.
Control materials, critical dimensions, cleanliness, and assembly steps.
Check leak, actuation, pressure, and system function as agreed.
Retain project-required identification, records, and change trail.
