产品简介：意大利STI***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, c***equently, the cylinder stem to be actuated.
The stem displacement is tran***itted 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.
