FEATURES

• Anodized aluminium body and coversprovides light weight together with

compactoverall dimensions.

• Simplicity of construction and ease of useare at the top of design and

constructionparameters.

• High torque and speed performance.

• All gearing running in the oil bath whichallows global high and constant

efficiency andlow power consumption.

• Manual operation by hand-wheel withengagement lever an automatic

disengagementin case of motor rotation. The handwheel doesnot rotate

when motor is running.

• Local indication of valve position by a devicemechanically connected to

the valve stem or,upon request, local dial indicator or remoteindication by

electrical switches

• Weatherproof as standard (IP 68 according toIEC 529]

• Explosion proof protection available in caseof requirements for electrical

components(limit switches, position transmitters,solenoid valves, etc)

• Mechanical stops available on request.

• Supply connections with quick connectorsand protecting Plugs

General Application

Morin Actuators are designed for on/off or modulating control of any

quarter-turn ball, butterfly, rotary plug or damper style valve application.

Technical Data

Supply pressure:  Maximum operating pressure 400 to 2250 psig or as

specified by nameplate.

Maximum shell pressure 2250 psig or as specified by nameplate.

Supply medium:  Any gas or hydraulic fluid compatible with materials

of construction.

Temperature rating:

Standard range: -20 to 210 °F

Optional range: -65 to 300 °F

Angular rotation:  90° ± 8°

Installation

The actuator is factory lubricated and does not normally require periodic lubrication

while in service. The actuator can be mounted parallel or perpendicular to pipeline.

The actuator can be installed in any convenient position including vertical, horizontal

or upside down.

A. Bolt mounting bracket to actuator hand tight. Do not tighten yet.

B. Install coupling on valve. Be sure rotary stops on valve are removed or

adjusted to allow actuator stops to do the stopping.

C. Install actuator and bracket to valve being sure to leave all fastener

connections hand tight. If possible, stroke valve and actuator to a half open

position 45° and physically shift actuator back and forth until coupling and

all fasteners are relaxed then tighten all bolts and nuts. This procedure will

accurately align valve stem to actuator output shaft and prolong valve stem

seal life.

D. Cycle valve/actuator assembly and observe for smooth operation.

E. Adjust travel stops for perfect alignment in both open and closed positions.

F. Tubing Connections – Tubing connections for the hydraulic supply are to be

attached as shown in Figures 1. 2 and 3. Note that on a two cylinder actuator,

the inboard end cap (adaptor) is vented and must not be connected to the

hydraulic or high-pressure gas supply.
