st-valve.com is the corporate website of 双泰阀门有限公司. The company is based in Oubei, Wenzhou, Zhejiang, and positions itself as a manufacturer of safety valves, pilot-operated safety valves, butterfly valves, and bi-directional pressure butterfly valves for industrial use cases such as boilers, chemicals, petroleum, power generation, metallurgy, pharmaceuticals, environmental protection, pressure vessels, and pressure pipelines.
The website mainly serves as a product showcase and procurement lead-generation channel. Its product range covers safety valves under Chinese, American, Japanese, German, and Russian standards, as well as segmented models such as spring micro-lift, full-lift, cryogenic, high-temperature and high-pressure, bellows-balanced, fluorine-lined, vacuum/negative-pressure, air-compressor, hydraulic, lever-type, and main safety valves. The site also states a capability range of DN8–3000mm nominal diameter, 0.25MPa–65.0MPa pressure, and -196℃–815℃ temperature, and emphasizes that non-standard and special designs can be manufactured according to customer requirements.
The official website does not publish prices and does not provide an online ordering module. Industrial valves of this kind are usually quoted individually based on medium, pressure rating, diameter, material, connection standard, certification requirements, and project delivery timeline. Buyers need to contact sales and technical staff by phone, WeChat, QQ, or email.
The main advantage is that qualification information is relatively complete: the site discloses Special Equipment Production Licenses for safety valves Class A and Class B, metal valves Class B, as well as ISO9001, ISO14001, ISO45001, CE, and other certifications. It also lists machining, inspection, and full-performance testing equipment, which helps improve credibility for industrial procurement. On the after-sales side, it promises a response within 12 hours for quality issues and, when necessary, on-site maintenance within 48 hours, making it relatively suitable for engineering project procurement.
The downside is that the website is still in the style of a traditional corporate site, lacking structured selection tools, complete catalog downloads, online quotations, inventory, and lead-time information. Some news dates appear to be set in the future, so buyers should independently verify how rigorously the content is maintained. Product detail pages are also limited in depth, and key parameters still need to be confirmed offline.
Suitable for procurement staff at boiler manufacturers, chemical plants, power stations, pressure vessel manufacturers, environmental engineering companies, oil and gas projects, and metallurgy projects, for initial screening of safety valve and butterfly valve suppliers.
The website has both ICP and public security registrations and is aimed at users in mainland China. It can be accessed directly from China.
