KP/KPM SERIES General Description Pneumatic rack and pinion actuators QUIFER are in the market for more than 40 years. These actuators are popular for their high resistance and durability and, in consequence, the reduction of the maintenance cost in the production lines. For that reason, our actuators are used in the most exigent markets and environments like oil and gas, offshore platforms or vessels. The linking surfaces of the actuators are designed according ISO 5211 and VDI/VDE 3845. Design of the actuator is constructed according ISO9001:2015, IEC 61508:2010, LOM 05ATEX6032 and...

Technical Data Linking surfaces according ISO 5211 and VDI/VDE 3845 Air connections according VDI/VDE 3845 Drive shaft with square ISO 5211 All components have high resistance to corrosion All models have a double opening and closing regulation from the outside Multiple combination springs allow a wide range of torques for one model All springs have a preloader, increasing safety All models are easily convertible from spring return to double acting and vice versa Options Low temperature versions up to -65ºC High temperature up to +180ºC Nickel plated actuators Stainless Steel drive shaft...

Double Acting Torques Chart (Nm.) 40 PSI 2,7 Bar 25% Safety factor is recommended. Air Volume And Operating Time Air Volume Per Stroke (Lt) Spring Return Double Acting These times are approximate (the test was made with a supply pressure of 6 bar, an ambient temperature of 20º, with electric valve of 680 l/min., tubling of provide of electric-valve of 8mm. of diameter and the actuator without load). If any of these parameters are modified, the times can be different.

180º Actuators Series Double Acting Dimensions Those actuators turn 180º by putting pressure either in the “O“ inlet or in the “C“ inlet. Torques and rest of the dimensionsare the same as thier respective standard models. 180º Actuators 3 Positions Dimensions Those actuators have 3 positions. The central position is reached by spring force, then i order to move 90º clockwise or anticlockwise is necessary to put pressures either in “O“ inlet or “C“ inlet. Torques and rest of the dimensionsare the same as thier respective standard models. Quifer Actuators www.quiferactors.com...
