Adrian Lim Profile Photo

Adrian Lim

Senior Process Engineer, Singapore

"In petrochemical projects, equipment failures are simply not an option. After 18 months of continuous use, the valves have performed without a single issue. What I value most is the structured way they handled the project—from clear technical drawings to full test reports. As a buyer, that level of documentation and predictability makes me confident I can integrate their products into large-scale operations without risk."
Katrin Hoffmann Profile Photo

Katrin Hoffmann

Plant Manager, Germany

"Managing a chemical plant means every delay translates into real financial impact. The valves we sourced maintained full reliability under highly corrosive conditions, and all certifications were delivered on time and ready for audits. What impressed me was their quality management system—it wasn't about one good shipment, but a consistent process. That gave me the assurance I could rely on them for long-term procurement."
Richard Collins Profile Photo

Richard Collins

Chief Engineer, United Kingdom

"Offshore conditions are brutal on equipment—saltwater, pressure, and long pre-commissioning cycles. After two years submerged, the valves were still performing exactly as specified. But what made the difference for me was not only the product itself, but the supply discipline: shipments arrived as scheduled, and communication was always direct and solution-oriented. That consistency reflects a factory system I can trust across international projects."

We focus on municipal water & wastewater, HVAC/building services, fire protection, shipbuilding/marine, and general industrial process water and utilities. As a manufacturer, we supply valves, strainers and piping components that integrate into EPC and system integrators' packages.

Core scope covers butterfly, gate, globe, check, ball, plug valves, foot/balancing valves and Y/Basket strainers. Typical ranges: DN25–DN1200, PN10–PN25, −10 °C to 200 °C; materials include ductile iron, carbon steel, stainless steel 304/316L and bronze. Designs follow DIN/EN/ISO with capability for ASME B16.34, API 609, DIN 3352 and EN 593; ANSI/DIN/JIS flanges available.

We operate under ISO 9001 with process checkpoints from incoming material to final assembly. Each unit is pressure tested at 1.5× working pressure, with QC records traceable by batch and operator. Third-party inspections (SGS/BV/TÜV) can be arranged on request; CE and DNV documentation is available where applicable.

Stocked/common specs can ship from ~5 working days; modified standard items typically 10–15 days; engineered-to-order usually 15–25 days. For urgent projects we can start production within ~72 hours and support phased deliveries or JIT under framework agreements.

We supply 2D drawings/3D models where needed, material certificates, pressure/leak test reports, operation & maintenance manuals and installation guides. All documents are available in English/Chinese and aligned with international project requirements.

We offer valve selection advice, flow resistance checks, materials compatibility evaluation and sealing scheme optimization, supported by CAD/CAE. Support is delivered remotely (video/phone/email) with 24-hour technical response. On-site installation or local maintenance is not included.

We support T/T and L/C; standard terms are 30% down payment and 70% before shipment, with credit terms for approved long-term partners. INCOTERMS®: FOB/CIF/DDP. Standard MOQ is 10 units (special items excluded). A 12-month quality warranty applies; issues are handled via remote diagnostics, repair or replacement per contract.

We export mainly to Europe, North America and Asia, including Germany, Italy, Spain, the United States, Japan, Singapore and Turkey. Factory verification options include on-site audits, third-party inspections, and provision of certificates/licenses and references.
