产品名称：意大利STI定位器DE/3M,SA/CL等
产品型号：DE/3M,SA/CL
产品简介：意大利STI定位器包含DE/3M,SA/CL,UP,FT等系列
The SA/CL positioner is formed by:
• a diaphragm on which the pneumatic control signal operates;
• a feed-back spring;
• a double acting spool valve connected to the diaphragm by rod.
Control pressure, operating on diaphragm, opposes to the spring, causing spool valve to displace and, consequently, the cylinder stem to be actuated.
The stem displacement is transmitted to the feed-back spring through cam and lever.
Therefore the actuator stem is a stable position only when the feed-back spring balances exactly the force generated by the pneumatic signal on the diaphragm and spool valve is in a neutral position.
