The Product You Receive Is The Product You Purchased
Product reliability and performance are directly related to quality and a major concern of any customer who must have the assurance they are receiving products as designed, with a material and quality level that meets or exceeds their requirements.
Material Verification and Traceability
Zaval in-house lab is equipped with fully calibrated equipment in accordance with international and NIST requirements for verifying chemical and physical properties of a wide variety of materials. Supplier's Material Test Report (MTR) and Zaval’s associated test verification are maintained indefinitely for all valve pressure retaining components.
Positive Material Identification
Trained operators using certified equipment perform in-house PMI testing to verify material traceability reports and ensure specific materials are utilized for valve assemblies.
Coordinate Measurement
Electro-mechanical machines utilize touch probing methodology (and analyze data via regression algorithms to interpret raw input against comparative information) throughout the engineering and manufacturing process to verify physical characteristics (such as dimensions and tolerances) of a part or assembly against its design intent.
