NERIKI DS-3H valves are carefully designed to obtain particle-free,high air tightness,super-clean
product.
This design,in turn prevents gas leakage and minimizes the dead space area.
NERIKI valves are manufactured with the up to date technology as well as the high quality control
systems currently available.
The valves are assembled in NERIKI high tech clean room assembly (class 10) and all valves are inspected,at all levels,with a Helium leak detector apparatus to 10atm cc/sec.
During transportation of cylinders,when Actuator or Handhwheel is removed from the valve,the DS-3H has an internal locking mechanism which assures safety.

NERIKI设计的DS-3H是为了满足无颗粒，高气密性和超纯净的应用的阀门。设计中考虑防止气体泄漏并最小化滞留区面积。
NERIKI的阀门的制造加工采用目前新科技和高级别质量控制系统。
NERIKI的阀门在NERIKI高科技洁净厂房内（10级净化厂房）进行组装且每颗阀门都被严格检查，氦检探测仪级别为10atm cc/sec
在钢瓶运输途中，当阀门驱动器或者手轮被拆除的情况下，DS-3H阀门会被内部的机械锁封闭以确保安全。
