Thousands of Introl Series C,D and G Actuators areinstalled around the world on projects for some of the worlds leading oil and gasproduction companies.Koso Kent Introl manufactures from its plant in the UK, with global sales and applicationsupport from specialist sales people and carefully selected channel partners throughoutthe world. Quality Manufacturing Maintaining the highest standards of quality throughout design, production andcustomer service is the cornerstone of Koso Kent Introls philosophy. Our plant isaccredited in accordance with Quality Management System ISO 9001 and EnvironmentalManagement System ISO 14001. In addition all chokes, where applicable, conform toATEX, PED and are CE marked accordingly. Safety is the key element in anything we do.Valve Fitted With Piston Actuator 2 Technical Bulletin T8500 - 0109 Series G Spring Return Diaphragm ActuatorThe G Series actuator is a well proven design, its robust design makes itsuitable for the majority of control valve applications. It is a field provendesign

(50,000 units first supplied in 1986. It is available in a number ofsizes, built with field reversible fail action with no additional parts. Performance Reliability. High Power. Full response. Low Hysteresis. Design Flexibility Reversible fail action without extra parts. Split Coupling for easy attatchment to valve plug stem. Wide selection of optional accessories available, many withoutmodification of standard unit. Involute rolling diaphragm simplifies actuator design. Variable travel / stroke up to 8. Design Integity Robust steel construction. Low stressed alloy steel springs. Twin seal seal box with wiper system. Quality Manufacturing High quality material with traceability throughout manufacture. Quality Assurance systems in accordance with ISO9000 2000 Comprehensively tested to ensure specified performance on site.The G Series diaphragm has been developed from lntrols highly successful A Series range. The useof an involute rolling diaphragm permits the long travels required without the need for the expensivehardware normally associated with rolling diaphragm types. A wide selection of spring ranges areavailable and the use of ball thrust races prevents torsional loads being applied to the diaphragm aswell as reducing the effort required to precompress the spring. The modular design allows retrofittingof many of the optional extras without modification of the basic unit. Forstandardapplicationsthediaphragm actuatoroffersthefollowing advantages over the conventional piston type:Simple cost effective design.- Increased life and reliability, accurate honed bores with delicate sealing systems are not required.- Low cost, simple

4 maintenance.- High performance, low fric
maintenance.- High performance, low friction rolling diaphragm gives comparable hysteresis with piston types.

It is available for the 075 and 150size actuators and may be fitted retrospectively withoutany modification of the standard unit. The handwheel iscapable of providing operating forces in either directionand does not rely on the actuator spring to providereturn motion. The handwheel can also act as a limitstop to limit either the amount of valve opening orclosing. Side Mounted Handwheel unit (Continuously Connected) (Fig.3 )This unit is available for all sizes of actuator with travelsup to and including 8.

LB KG LB Technical Bulletin T8500 - 0109 The C Series Spring Opposed Piston Pneumatic Actuator is manufactured in 300 insize. The Actuator designcombines strokes up to 6 ins with spring powers up to 8700 Lbf (3590 Kg) and is used for both positivethrottling and on/off applications, for Automatic Control Valves. The all steel construction ensures safe workingpressures up to100 psig (6.9 Bar), the single-spring power unit giving distributed loadings for smooth operation.The piston fitted with seals operates in a honed steel cylinder which provides for smooth travel, minimisinghysteresis and wear.To ensure in-build reliability and low maintenance costs, the actuator is designed without linkages, and there areminimum of working parts.The actuator air fail position may be reversed by inverting the spring/piston unit, re-assembling the yoke andstem cover plate. the frequency response of the introl Piston Actuator is extremely high. Linear response tosignal change is unaffected by the increasing or decreasing pressure, sensitivity being maintained over theworking range.The Series C actuators are always operated through a valve positioner and an alternative of two types areavailable depending upon the application requirements.From the C Series the D Series actuator was developed, the spring return feature is removed and a seal plateunit is inserted. Series C Pneumatic Spring Return Piston ActuatorThe C Series actuator is a well proven design, its robust design makes it suitable for the majority of control valveapplications. It is a field proven design (50,000 units first supplied in 1986. It is av

Quality Assurance systems in accordance with ISO9000 2000 Comprehensively tested to ensure specified performance on site. Fig. 11 D series Pneumatic DoubleActing Actuator The D series double acting piston has been developed from the original C series piston actuator, which usedthe spring return feature.When operating as a D series actuator, the spring return feature is removed and a seal plate inserted. thisprovides the basic facility of double acting piston where extra power may be obtainted for the air fail action, byreleasing a stored volume of air contained within a separate tank. This range is available for valve strokes up to12 ins. Ancillary equipment comprising of a 3-way switching valve, lock-up valve, check valve, is required inaddition to volume tank and pipework. The existing positioner is optioned for double action operation.HandwheelsA side mounted handwheel of the continuously connected type is available foe both C and D series actuators.The unit is always mounted on top of the actuator and can be fitted retrospectively without anyadditions/modifications to the existing actuator and without removing the actuator from the valve.Because the unit is mounted on top of the actuator it allows it to be totally enclosed, thus preventing the ingressof any extraneous matter and hence increasing the life of the unit between service intervals. The gearing has been selected to ensure easy operation even with the maximum actuator powers.A declutchable handwheel unit is also available for the C and D series actuator
