按表中规定的温度范围或标明你想控制的温度范围。
测温毛细管长度。8英尺是标准尺寸。
测温探头形式：T、TU、TUBW、TUSW、TBW&TSW.
“P”型压力先导阀
请标明：
表中的调节弹簧压力范围
调节阀主阀
请标明：
D系列或HD系列调节阀
调节阀接口尺寸或蒸汽流量
接口形式（BSPT或NPT 螺口，PN16 / 125# / 150# / 250# / 300# 法兰）

工作原理
使用压力与温度先导阀的组合可同时对调节阀进行调节。当温度先导阀控制蒸汽温度的同时，压力先导阀控制减压阀出口的压力。温度先导阀可通过感应系统的温度来控制调节阀的开与关。压力与温度先导阀的组合避免使用两个单独的调节阀。
