Overview
对许多蒸汽加热工艺而言,产品质量依赖准确的温度控制,而能源效率则依赖在达到目标温度后及时减少蒸汽流量。斯派莎克自作用温度控制系统提供了一种无需外部动力即可实现这一目标的简单方案。 这类系统依靠自作用感温和阀门动作,而不是电力或压缩空气,因此当公用工程条件有限、危险区域适用性重要,或现场希望避免不必要控制复杂度时,它们非常有吸引力。 自作用温度控制通常很适合成套设备、OEM 装置、伴热系统以及一般过程加热工况,在这些场合中,比例调节和可靠重复性往往比高级自动化功能更重要。 安装简单、调试工作量低以及维护需求适中,都有助于降低全生命周期负担;同时,由于没有电子控制硬件,在潮湿、偏远或公用工程受限环境中也更实用。 因此,当运行工况足够稳定,能够从一种可靠且内在简单的温控方式中受益时,这一系列产品为用户提供了区别于执行器驱动调节阀的有效替代方案。
Continue your temperature control selection
Self-acting temperature controls are most useful when a simple, power-independent control solution is preferred over a more complex actuated loop.
See the wider temperature control context
Return to the wider control systems range when self-acting temperature control is one option within a larger steam control strategy.
Compare self-acting and actuated control
Use the control valve range when the duty needs tighter actuated modulation, different trim options or integration into a powered control loop.
Support the full steam control station
Review pressure reducing and surplussing valves when temperature control also depends on stable upstream steam pressure or complete station design.
