ROSS阀DM2® D系列介绍

DM2® D 系列双阀是一款获得专利的 3/2 常闭阀（带中间锁定位置），其特点是主阀杆上带有 SERPAR® 横流通道、锥阀和滑阀。这种布置赋予了阀门流量特性和集成监控功能，并带有总记忆功能。该阀门提供动态监控和动态记忆功能。

动态监控意味着所有监控组件在每个阀门循环中都会改变状态。如果阀芯异步循环，阀门将排出下游空气并锁定，从而禁止进一步操作。

监控系统中的动态记忆功能表明，当阀门锁定时，无论空气或电气状态如何变化，阀门都将保留故障信息。DM2® 系统只能通过定义的操作/程序复位，并且不会自行复位（关闭和打开阀门），也不会在切断并重新通入进气时复位。这种自动复位会向操作员隐藏潜在危险。

The DM2® Series D double valve is a patented 3/2 normally closed valve (with an intermediate, lockout position)  distinguished by SERPAR® Crossflow passages with poppet and spool valving on the main  valve stems. This arrangement provides  the  valve’s outstanding flow characteristics and an integrated monitoring capability with total memory.  The valve provides dynamic monitoring and dynamic memory.

Dynamic Monitoring means that all monitoring components change state on every valve cycle.  Should the valve elements cycle asynchronously, the valve will exhaust downstream air and lock-out, prohibiting further operation.  

Dynamic Memorywithina monitoring system indicates that when a valve lock-out occurs, the valve will retain the fault information regardless of air or electrical changes. The DM2® system can only be reset by a defined operation/procedure, and will not self-reset (turning the valve off and on) or reset when inlet air supply is removed and re-applied. Such automatic resetting would conceal potential hazards from the operator.
