1. 设计
　　所有阀门都是按照ASME B16.34的要求进行设计，也可以按照ASME标准和用户的特殊要求进行设计。
　　1. DESIGN
　　All valves are designed to comply with the requirements of ASME B16.34, the ASME code and specials to customer requirements as applicable.

　　2.质量保证
　　从原材料采购到生产、焊接、总装、检验和包装的每个阶段，都是按照品管手册里书面的规定进行操作。（ASME第III节手册适用于阀门生产，ISO 9001 品管手册适用于所有其它产品生产。）Velan的四个北美工厂获得ISO 9001认证，工厂1和工厂2拥有ASME“N”标记授权，工厂3拥有鉴定证书。每个订单都要由工程部和品管部进行复核，所有特殊的用户要求都汇总到针对每个工程发布的QCI（质量控制说明书）中。品管部也操作校准和仪表控制系统，培训和认证熟练焊工和NDT检察员。
　　2. QUALITY ASSURANCE
　　Every steps from procurement through production, welding, assembly, testing and packaging is in accordance with written rules contained in QA manuals. (An ASME Section III manual for code valve production and an ISO 9001 QA manual for all other production.) Velan's four North American plants are certified to ISO 9001 and Plants 1 and 2 have ASME "N" stamp authorization, Plant 3 has a certificate of accreditation. Orders are reviewed by Engineering and QA Departments and all special customer requirements are incorporated into QCI (Quality Control Instructions) issued by each project. The QA Department also operates calibration and gauge control systems, and trains and qualifies skilled welders and NDT inspectors.

　　3. 质量控制
　　品管部门对质量全面负责，从收到材料到制造过程、焊接、非破坏性是测试、总装、压力测试、清洗、油漆和包装的管理。如果需要，一个完整的质量目标永久性纪录就会以“Velan资料包”的形式收集并寄送给用户。
　　3. QUALITY CONTROL
　　The QC Department is responsible for all aspects of quality, from receiving of material to control of machining processes, welding, nondestructive testing, assembly, pressure testing, cleaning, painting and packaging. When required, a permanent record of all completed quality goals is prepared and sent to customers in the form of a "Velan Data Package".

　　4. 压力测试
　　每个阀门都要按照ASME B 16.34、ASME法典，或特别用户的要求的标准进行压力测试。在所有工厂，测试设备都集成在生产控制/库存管理软件中。
　　4. PRESSURE TESTING
　　Each valve is pressure tested in accordance with ASME B16.34, the ASME Code, or special customer requirements as applicable. In all plants test status is integrated into production control/inventory management software.

　　5. 改善团队
　　在制造过程的各个点上的改善团队，保证在源头、过程控制、更高的工艺技术和操作者权利等方面的质量。
　　5. IMPROVEMENT TEAMS
　　Continuous improvement teams at point of manufacturing, ensure quality at source, process control, higher workmanship and operator ownership.

　　6. 合格性测试
　　通过功能性合格测试来检验可靠性。所有阀门都要经过这些测试，以确定其可靠性和使用寿命。
　　6. QUALIFICATION TESTING
　　Reliability through functional qualification tests. These tests are performed on all valves to determine reliability and service life.
