Technical FAQ: High Quality Wafer Check Valve Manufacturer Insights

Q1: What is the difference between CF8M and WCB in wafer check valves?
CF8M is austenitic stainless steel (316 equivalent) with outstanding corrosion resistance; WCB is cast carbon steel, suitable for non-corrosive or less demanding environments.
Q2: How are cycle life and performance validated?
Per API 598/ISO 5208, random sampling undergoes pressure/leak tests over 80,000–150,000 open/close cycles at rated pressure/temperature.
Q3: What international standards govern high quality wafer check valve factories manufacturing?
Major ones include API 594, API 609, ISO 9001:2015, CE PED 2014/68/EU, and ANSI/ASME B16.1 or B16.34 for dimensional/interchangeability fit.
Q4: Which seat materials should be used for corrosive media?
EPDM and PTFE are preferred for acids and chlorinated water, while NBR is commonly used for oils/fuel. For brine, PTFE is optimal for anti-permeation.
Q5: Can high quality wafer check valve suppliers provide project-matched documentation?
Yes, leading suppliers can issue EN10204 3.1 certificates, hydrostatic/airtight test records, and full traceability reports matched to heat/lot numbers.
Q6: What are the best practices for valve installation?
Ensure flow arrow orientation matches pipeline direction, center the valve precisely, and avoid excessive bolt torque that may deform the wafer body. Consult ISO 5208 or API 609 mounting guides.
Q7: How are lead times and delivery expedited for urgent projects?
Many high quality wafer check valve suppliers maintain inventory for core sizes (DN50–DN400, Class 150, PN10/16), and offer express processing for urgent export via airfreight with digital QA documents within 2–3 weeks.
