The Complete Guide to T-Type Strainer
Learn how T-type strainers remove rust, scale, welding debris, and other solid particles before they reach pumps, control valves, flow meters, and downstream equipment. The guide explains their working principle, installation and maintenance requirements, and key selection factors such as flow rate, screen opening, debris capacity, allowable pressure drop, pipeline orientation, and cleaning access.
Through Shaft vs Split Shaft Butterfly Valve Discs
Compare through-shaft and split-shaft butterfly valve discs by shaft structure, mechanical strength, flow resistance, operating torque, weight, cost, and suitable valve size. Through-shaft designs provide strong, simple support for small- to medium-size valves, while split-shaft designs create a less obstructed flow path and are better suited to large-diameter, flow-efficient systems.
Concentric vs Eccentric Butterfly Valve
Compare concentric and eccentric butterfly valves by shaft position, seat contact, sealing design, operating torque, pressure and temperature capability, service life, and application. Concentric butterfly valves provide a simple, economical solution for water, HVAC, and low-pressure utility systems, while double- and triple-eccentric designs reduce seat friction and offer more durable sealing for steam, gas, chemical processing, power generation, and other demanding services.
Can a Check Valve Be Installed Vertically?
Can a check valve be installed vertically? This in-depth guide explains vertical check valve installation rules, suitable valve types, common mistakes, and engineering best practices from Vcore Valve.
Why Install a Check Valve at the Pump Outlet?
Learn why check valves are installed at pump outlets to prevent reverse flow, reverse pump rotation, water hammer, seal damage, and unstable system operation. The guide also explains proper installation position, valve selection, and why fast-closing designs such as nozzle check valves are often preferred for pump discharge lines.
Butterfly Valve Disc Material Selection Guide
Compare common butterfly valve disc materials—including epoxy-coated ductile iron, stainless steel, aluminum bronze, and coated discs—by corrosion resistance, mechanical strength, operating torque, temperature capability, cost, and media compatibility. Epoxy-coated ductile iron suits water and HVAC systems, stainless steel is preferred for chemical and hygienic service, and aluminum bronze provides strong seawater resistance for marine and offshore applications
Resilient Seated Butterfly Valve Seat Design Guide
Compare booted, molded-in, and cartridge seat designs used in resilient-seated butterfly valves. The guide explains how seat retention, replaceability, flange sealing, pressure and vacuum capability, operating torque, media compatibility, maintenance access, and lifecycle requirements affect the selection of a suitable butterfly valve seat configuration.
Extended Stem Butterfly Valves for Underground Pipelines
Learn how extended stem butterfly valves allow buried pipeline valves to be operated safely from ground level or inside a valve box without excavation. The guide explains stem length selection, valve box compatibility, corrosion and ingress protection, torque transmission, installation planning, and routine inspection considerations for municipal water, utility, and underground industrial pipeline systems.

The case highlights key factors such as backflow prevention, PN10/PN16 pressure ratings, flanged connection, rubber-coated ball construction, cold-environment considerations, pressure testing, export packaging, and supplier reliability for international valve projects.
Manual Knife Gate Valves for Brazil: Slurry and Wastewater Application Case
Learn how manual knife gate valves were selected and delivered for slurry, solids, fibrous media, wastewater, and industrial discharge applications in Brazil. The case highlights key factors such as rising-stem handwheel operation, replaceable resilient seats, DN80–DN300 flanged construction, pressure and sealing tests, export packaging, and valve selection for demanding South American industrial projects.
How to Fix a Leaking Butterfly Valve: Causes, Inspection and Repair Guide
Learn how to troubleshoot and repair a leaking butterfly valve by identifying whether leakage comes from the seat, shaft, flange, body, or sealing surface. The guide explains common causes such as worn seats, damaged O-rings, misalignment, over-tightened flange bolts, material incompatibility, corrosion, and excessive pressure, while outlining safe isolation, inspection, repair, replacement, and preventive maintenance steps.
