Professional Centerline butterfly valve
Centerline butterfly valves feature simple structures, easy manufacturing and small installation spaces. For critical applications, consult Tianyu Valves—we customize materials, seals and certifications per project needs.
In the realm of pipeline operations—where hazardous fluids, high pressures, and unforgiving environments are commonplace—safety is not just a priority but a non-negotiable requirement. Pipelines transporting crude oil, natural gas, chemicals, or cryogenic fluids demand isolation solutions that prevent leaks, enable safe maintenance, and mitigate environmental and operational risks. Among the most critical components in […]
The pharmaceutical industry demands uncompromising standards for product purity, process safety, and regulatory compliance. Even the smallest trace of contamination—from valve materials, dead zones, or inadequate cleaning—can lead to batch rejection, costly recalls, or risks to patient health. Among industrial valves, 3-piece stainless steel ball valves have emerged as the gold standard for pharmaceutical applications, […]
Offshore oil and gas platforms operate in one of the harshest industrial environments—constant salt spray (35,000 ppm chloride concentration), extreme pressure (up to 42 MPa), temperature fluctuations (-20°C to 150°C), and limited operational space. Valves, as critical flow control components, face unique maintenance challenges: traditional side-entry or bottom-entry ball valves require full pipeline disassembly for […]
Ball valves are ubiquitous in industrial fluid handling—from oil and gas pipelines to chemical processing—due to their fast 90° actuation, tight sealing, and durability. However, selecting between full port (FP) and reduced port (RP) designs is critical: it directly impacts flow efficiency, energy consumption, and long-term operational costs. Full port valves feature a ball bore […]
Introduction Seawater intake systems are vital for power generation (cooling), desalination (raw water), and offshore oil/gas (injection water). However, seawater’s contaminants—suspended solids (20–100 mg/L), marine organisms (barnacles, algae), and sediment—damage downstream equipment (pumps, RO membranes). Basket strainers with 316L stainless steel mesh solve this: they capture debris while resisting seawater’s 35,000 ppm chloride corrosion. This […]
