Failure Analysis, Manufacturing Evidence and Quality Control

Common misapplication risks: incorrect thread or connection standard, insufficient certified relieving capacity, unsuitable body or trim material, operating pressure too close to set pressure, unreviewed back pressure, and installation loads transferred to the valve.

Material review: body materials: Stainless steel body and clean-service material options, typically 304/316/316L according to order. Trim and internals: Stainless steel trim suitable for clean steam, gas or liquid service. Spring and stem: Stainless or clean-service spring material according to cap type and medium.

Testing and inspection: Set pressure calibration, shell strength test, seat tightness/leakage test, reseating/blowdown check, dimensional inspection and material verification can be supplied according to the confirmed standard and order requirements.

Source and scope: product data is based on Zobai Safety Valve Product Catalog.pdf, catalog page 051-052. Project compliance remains subject to the approved datasheet, drawing, calculation and controlled certificates for the ordered configuration.
