ZZJG's Advantages

40 Years of Marine Mastery. 5 Years of Unbreakable Performance.
Triple-offset precision eliminates friction → perfect seat-to-disk seal. No seawater seepage. No fines. No operational shutdowns.
Duplex 2205/2507, C95800, and Inconel® alloys engineered to annihilate chloride pitting and SCC in saltwater. 2–3× longer life than carbon steel valves.
Extreme Pressure Mastery (430 barg / 6,235 psi): Built for deep-sea pipelines and high-flow production systems—no pressure surges, no valve failures. Handles the harshest offshore conditions.
Unbreakable Temperature Resilience (-254°C to 750°C): Operates flawlessly in LNG cryogenics, steam loops, and scorching seawater environments—no thermal stress, no seal degradation.
Universal Pipe Compatibility (DN50–1200mm / NPS2"–160"): Fits every seawater system—from desalination plants to offshore rigs. No custom fittings. No installation headaches.
5-Year Warranty: Backed by 40 years of field data—not just a promise, but a commitment. Zero replacements. Zero downtime.50% Lower Downtime Costs.

Why ZZJG Butterfly Valves?

API 609 International Certification

Fully compliant with API 609 international standard, covering all structural types including double flange, lug, and wafer types, and has obtained global market access qualifications for the petroleum, chemical, and power industries. Class 150 ~ 2500 (PN20 ~ PN420), NPS2" ~ NPS200" (DN50 ~ DN6000), temperature range -40℃ ~ 600℃, zero-leakage, and fireproof with API 607.

Leading Eccentric Structure Design

Double and triple eccentric design, the valve shaft, valve seat, and pipeline centerline are precisely offset, significantly reducing friction and wear. Bidirectional zero-leakage pressure, with built-in anti-sludge and self-cleaning functions, suitable for harsh media such as sewage and slurry, and with a service life more than 3 times longer than conventional butterfly valves.

Reliable and Guaranteed Quality

Founded in 1981 and located in the valve capital of China, this company is a certified National High-Tech Enterprise with R&D investment exceeding 5%. Its 12-step full-process testing procedure, from material verification to finished product delivery, adheres to API 609 inspection standards to ensure zero-defect delivery.

Customized Services for All Conditions

Adaptable to all media including water, steam, oil, acids, alkalis, and gases, meeting the needs of core industries covered by API 609, such as petroleum, natural gas, chemical, and power. Specialized models are developed for different scenarios, such as fully welded, leak-free butterfly valves for heating pipelines and hydraulically controlled slow-closing check valves for hydropower stations.
