XSTOU 25P導閥型蒸汽減壓閥為導閥型隔膜式，有法蘭和螺紋連接，聯系在線客戶可提供樣本；斯派莎克25系列導閥型隔膜式調節閥，通過對同一主閥、不同型號導閥的多元化組合，可控制蒸汽壓力。XSTOU 25P導閥型蒸汽減壓閥在普通減壓閥的基礎上做了很大的改進。膜片采用了新型材料，并大大加工了工作面積，因此閥門上游壓力或下游負荷細微的變化都能及時準確的反饋到主閥膜片，來調節主閥的開度，確保下游壓力的穩定。
The XSTOU 25P pilot valve steam pressure reducing valve is a pilot valve diaphragm type, with flange and threaded connections. Contact online customers to provide samples; The Spark 25 series pilot valve diaphragm type regulating valve can control steam pressure through diversified combinations of the same main valve and different types of pilot valves. The XSTOU 25P pilot valve steam pressure reducing valve has made significant improvements on the basis of ordinary pressure reducing valves. The diaphragm adopts new materials and greatly processes the working area, so subtle changes in upstream pressure or downstream load of the valve can be timely and accurately fed back to the main valve diaphragm to adjust the opening of the main valve and ensure the stability of downstream pressure.

結構特點：

■ 溫度調節刻度盤：快速準確的設定所需溫度。

■ 溫度感應器：在溫控元件中有無需補償的液體，感應瞬時溫度的變化，提供準確的控制。

■ 測試每一個25系列的調節閥在出廠前都經測試，以確保無故障的操作。

Structural features:

Pilot valve spring: Three colors of springs can provide accurate control of different pressures within the range of 0.2-14 bar g.

Temperature adjustment dial: quickly and accurately set the required temperature.

Temperature sensor: There is an uncompensated liquid in the temperature control element, which senses instantaneous temperature changes and provides accurate control.

Each 25 series regulating valve is tested before leaving the factory to ensure fault free operation.

工作原理：

25P蒸汽減壓閥，斯派莎克減壓閥啟動前導閥彈簧處于自由狀態時，主閥和導閥處于關閉狀態。導閥由彈簧力作用打開，蒸汽經由導閥進入主隔膜室，一部分蒸汽則經由控制孔流出，當由導閥流入的蒸汽大于由控制孔流出的蒸汽，主隔膜室中的控制壓力增大，打開主閥。隨著蒸汽流過主閥，下游壓力的增量經由感應管反饋，作用在導閥膈膜下，平衡隔膜上部的彈簧壓力，使導閥逐漸關閉節流，維持主隔膜室中的壓力，控制主閥開度輸送適量的蒸汽。調節導閥隔膜上的彈簧即可改變下游壓力。
