2 General These adjustment and maintenance instructions apply to the 0900 Series Actuators used with the Masoneilan 00 Series Pressure s. They include a parts reference list including recommended spare parts (see pages & ). For installation, operation, adjustment and maintenance of the 00 Series s body S/A refer to instructions Nos indicated by the following table. Model No ; -0 ; -0 H; H-0 H; H-0 V; V-0 Body S/A Instruction No EY 00 E ; EY 0 E E 9 E Spare parts When performing maintenance always use Masoneilan replacement parts. Parts are obtainable through your local Masoneilan Representative or Spare Parts Department. When ordering parts, always include Model and Numbers shown on serial plate. Description-Operation The 0900 Actuator is a simple powerful mechanical device. It is Air-to-Extend type. The nominal range of an actuator is the pressure range in pounds per square inch (psi) in which the pressure setting can be obtained by adjustment. Conformation of the diaphragm () to the diaphram plate (0) serves as a flexible upper guide for the actuator stem (). Nylon reinforced neoprene diaphragms permit smooth, sensitive operation. The lower guide is an oil impregnated bronze bushing () located in the spring adjuster (). Note: On request, for special services, the nylon reinforced neoprene diaphragm may be provided with a PTFE coating. The 0900 Series Actuators are designed for use with the 00 Series s for reducing, back pressure and differential pressure applications.

Contact the nearest Masoneilan Sales Office or Representative or, directly the After Sales Department of Condé-sur-Noireau Plant. Training MASONEILAN regularly holds training seminars for technicians in its factory of Condé-sur-Noireau. In order to participate in one of these training seminars you should get in touch with our local Masoneilan Representative or our Training Department. The following instructions should be thoroughly reviewed and understood prior to installing operating or performing maintenance on this equipment. Only qualified personnel to service this equipment. Non-compliance with safety rules and caution notes of this instruction may bring about malfunction of the device or damage it seriously. In addition, such negligence might expose personnel present on the field to grave hazards. The opposite chart indicates the combinations available to provide the desired function. The 0900 Series Actuators are designated by the nominal range (psi). See the following chart. In Spring Diaphragm Actuators, three actuator cases are available: a case rated for 0 psi static pressure, a case rated for 0 psi static pressure and a case rated for 0 psi static pressure. In Differential Pressure Actuators, two actuator cases are available: a low-pressure case rated for 0 psi static pressure, and a high-pressure case rated at 00, 000 and 00 psi static pressure.

If installed otherwise, an adequate condensate barrier must be incorporated. In the Spring Diaphragm Actuators, the / NPT pressure connection is located on the upper diaphragm case (). ➂ Qty: on Low Pressure Case Design Qty: on High Pressure Case Design In the Differential Pressure Actuators, the / NPT high pressure connection is located on the upper diaphragm case () and the / NPT low pressure connection is located on the diaphragm chamber (9) or on the connection adapter (9). Refer to s Body S/A Instructions for installation according to the regulator function.

5 Adjustment When pressure setting has been specified in order, the regulator is set accordingly at the factory for test. Then, the spring compression is fully removed to avoid unnecessary stress to parts (diaphragm, spring) during the stocking. It is necessary to proceed with adjustment before servicing. The regulator pressure range is engraved on the serial plate. Proceed as follows : Open controlled pressure line valve(s) and check setting by means of the gauge(s). Set by means of the spring adjuster () of the actuator. (To increase pressure setting (or pressure differential), turn adjusting screw clockwise to compress the spring. To decrease the setting, turn adjusting screw counterclockwise to relieve spring compression). Fully open stop valve on the inlet side of the regulator. Open stop valve on the outlet side of the regulator and partially open stop valve on the inlet side, allowing pressure in the system to build up slowly. Maintenance CAUTION: must be isolated and pressure vented before disassembly. Replacing diaphragm On spring diaphragm actuators (00 series s), (Figure ) Remove the controlled pressure line from the diaphragm case () and relieve all spring compression by unscrewing spring adjuster (). Remove upper diaphragm case (), [nuts () and screws ()], [not screws () on 0-0 psi range]. a) On 0,- ;,- ; -0 ; -0 and -0 psi ranges: Remove locknut (), diaphragm washer () and diaphragm (). b) On 0-, 0- and 0-0 psi ranges: Remove diaphragm screw (9), seal washer (0), stop cup () and diaphragm (). c) On 0-0 psi range: Remove diaphragm (). Note: By means of a wrench applied on the plug stem nuts, hold the actuator stem during this operation. Install new diaphragm and reassemble by reversing of the above description order. Readjust the spring compression (see above). On differential actuators (00-0 series s), (Figure ) a. On low pressure case design: Remove the high and low pressure lines from the diaphragm case () and the diaphragm chamber (9). Relieve all spring compression by unscrewing spring adjuster (). Remove nuts () and cap screws (). Remove upper diaphragm case (). Remove locknut (), upper diaphragm plate (), upper O-Ring (), washer () and diaphragm (). Install new diaphragm and reassemble by reversing of the above description order. Replace upper O-Ring () if necessary. Readjust the spring compression (see above). b. On high pressure case design: Remove the high and low pressure lines from the diaphragm case () and the diaphragm chamber (9). Relieve all spring compression by uncrewing spring adjuster (). Remove nuts (), upper diaphragm case () and diaphragm (). Install new diaphragm and reassemble by reversing of the above description order. Readjust the spring compression (see above). Replacing O-ring(s) ()(low and high pressure case) On differential actuators, (Figure ) Disassemble the actuator head as described on the paragraph : Replacing diaphragm, (see page ). Remove diaphragm chamber (9) with plunger S/A (). With a wrench applied over O-Ring retainer (), unscrew it out of diaphragm chamber (9). Remove O-Ring (), being careful not to damage plonger. Install new O-Ring, replace and tighten O-Ring retainer (). Reassemble and readjust spring compression, (see page ). Caution: Uniformly tighten all diaphragm case nuts () when reassembling.
