Valve Stem Seal Guide: Types, Function & Selection
Quick Overview A valve stem seal is an essential component that prevents leakage along the valve stem while allowing smooth movement during operation. Proper design improves reliability, reduces emissions, and extends the life of industrial valves. This guide from Vcore Valve explains the types of valve stem seals, materials, and practical selection tips for high-performance […]
Soft Seat vs Metal Seat Ball Valve Explained
Compare soft-seated and metal-seated ball valves by sealing performance, temperature capability, media compatibility, operating torque, service life, and cost. Soft seats such as PTFE, RPTFE, and PEEK provide bubble-tight shutoff and low torque for clean, moderate-temperature fluids, while metal seats with hardened coatings are better suited to high-temperature, abrasive, corrosive, fire-safe, and severe-service applications.
