On 13 May 2026, certificate of conformity No. UZ.SMT-01-0103-206173 for electric control valves manufactured by Wuhan TimeWave Network Technology Co., Ltd (China) was registered in the State Register of the National Certification System of the Republic of Uzbekistan. The certificate was issued by the "Toshkent" product certification body and is valid until 14 May 2028. The applicant is ERKSONS TRADE LLC — the official distributor of Wuhan TimeWave products in Uzbekistan.
The standards the valves comply with
The certificate confirms compliance with the following normative documents:
- ГОСТ МЭК 60204-1-2020 — safety of electrical equipment of machines and mechanisms;
- ГОСТ 12.2.007.0-75 — safety requirements for electrotechnical products;
- ГОСТ 5761-2005 — general specifications for pipeline valves.
Certification followed practical testing of DN50, DN100 and DN150 valve samples in accredited testing laboratories — independent confirmation that the equipment meets industrial safety requirements and is ready for operation at natural gas metering stations.
What this means for businesses
For wholesale gas consumers, the certificate answers the key question when choosing a remote shutoff device: the equipment is officially approved for use in Uzbekistan. TimeWave valves:
- provide remote opening and closing of the gas supply on a command from the operator or the billing system;
- report state and archives in real time through an RTU controller with 4G LTE;
- integrate with corporate information systems — billing, SCADA, accounting platforms — via the API of our gas monitoring software;
- meet industrial safety requirements and ship with technical documentation.
