VALTORC沃泰克气动执行机构的简单介绍UM-900A系列拨叉式气动执行机构，采用活塞双导向设计，活塞运动平稳可靠，具有输出力矩大、安装维护方便等特点。通过活塞密封环密封，使气源压力作用在活塞上产生移动，带动推杆或左或右移动。VALTORC沃泰克气动执行机构的详细信息The Series hydraulic scotch yoke actuators deliver the optimum output from the linear movement of the piston. This is ideal for quarter-turn valve applications and it is available in symmetrical and canted designs to suit specific valve characteristics. The actuator piston rod is tied to a guide block and supported by a high strength alloy steel guide rod with self-lubricated bearings. This improves the transfer of energy from the actuator to the valve stem. The series is smaller than other actuators offering similar torque outputs, which reduces the overall valve packages envelop allowing for a more compact design. The two full length keyways simplify actuator with valve assembly and allow easier modification of the actuator orientation to accommodate last minute pipe work changes. |
