The various points where seals are used are highlighted in red. 7 7 3 3 3 3 The mechanical drive arrangement should be described, pointing out its simplicity, Three rotating parts, the rotor and wormshaft, the wormwheel and output centre column, the drive to the output turns counting system. The incremental encoder (counter) consists of a magnet and two 慼all effect?switches which give electrical pulses to the position processor. this is infinitely more simple than complex gear mechanisms with multitudes of LEDs and photo transistors. (To a power plant customer) Lets assume a turbine coming on load 2 times a day. The average isolating valve will take an average of 1 min to operate. Then, including commissioning the actuator will do about one month抯 work in a 20 year life span of the plant. (To the water or sewage works operator) (To the oil movements operator) How many operations is the average valve on your plant to make? so how long will the actuator operate in-say 1 year. Wear for most electric actuators is usually negligible so after a period of possible miss-use the actuator has to sit there holding a valve position reliably until called upon to operate. Reliability is therefore dependant upon the actuator manufacturer taking care of these two main items. Foundation is brand new. The system is yet another Open system
