Industrial Valve Failures and Repair | Causes & Solutions
Learn the common causes of industrial valve failures and how to decide whether a valve should be repaired, refurbished, or replaced. The guide explains leakage, sticking, jamming, actuator failure, cavitation, erosion, material mismatch, sealing damage, predictive maintenance, inspection records, pressure testing, and root-cause analysis for improving valve reliability and reducing unplanned shutdowns.
How to Tell If a Valve Is Open or Closed: Position Indicator Guide
Learn how to determine whether a valve is open, closed, or partially open by checking handle direction, stem position, handwheel travel, actuator indicators, position feedback, flow response, and operating records. The guide explains common valve position indicators for ball valves, gate valves, globe valves, check valves, and automated valves, while highlighting inspection, maintenance, lockout/tagout, and safety practices that help prevent misoperation in industrial, HVAC, plumbing, and process systems.
How to Tell If a Valve Is Open or Closed: Practical Position Guide
Learn how to tell whether a valve is open, closed, or partially open by checking handle direction, stem position, disc orientation, flow indicators, actuator feedback, and system response. This practical guide explains common open/closed rules for ball valves, gate valves, globe valves, butterfly valves, and automated valves, while highlighting safety checks, labeling practices, and lockout/tagout precautions for plumbing, HVAC, utility, and industrial piping systems.
Analysis of Valve Problems: Diagnosis and Prevention Guide
Use this analysis of valve problems to diagnose leakage, stuck operation, corrosion, cavitation, actuator faults and wrong valve selection before repair or RFQ.
