4890A型音量增强器是一款坚固耐用的精密仪器，具备多项关键功能，可确保可靠、高效且稳定的运行。这些功能包括：功能
• 供气阀与排气阀之间设有固定死区，确保阀门最终位置准确且稳定。
• 集成旁通针型阀，优化响应时间和稳定性。
• 软座式供气阀和排气阀可实现高效无泄漏运行，并在与现代电子进气/排气式定位器配合使用时防止“追逐”现象。
• 压力平衡式供气阀保持死区规格不变，当供气压力变化时，不会影响控制特性。
• 振动阻尼的隔膜控制腔室，可在高流量条件下保护阀门免受有害振动损伤。
• 连接至出口腔室的两个附加端口，便于接入额外的控制附件及压力监测设备。
• 打孔排气口可用于收集排气空气或集成排气装置。消音器
