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.

The BIFFI PHW Power Hand Wheel series has been engineered and manufactured to provide easy and quick operation ofpipeline valves equipped with a gear reducer instead of the operation of turning manually the gear reducer’s hand-wheel. GENERAL APPLICATION Power Hand Wheel Unit is designed for theoperation of linear and quarter turn valveson pipelines where power source (Electric,Pneumatic, Hydrauliclis not available. TECHNICAL DATA Ambient Temperature: from-30C to 80C Oil Flow rate into the range: rom 10 V/min to 60 V/min Supply Medium: Mineral oil Oil Max Flow rate(for 140 bar max oil pressurel: 70V/min Oil Supply pressure into the range: from 25 barg to 170 barg Output torques (without bevel gearl: up to1200 Nm Max. Supply pressure (for intermittent duty): 200 barg Speed (without bevel gear): up to 144 rpm (higher speeds on request）  

Bi-directional travel stops Adjustable stops on each end cap provide the flexibility of accurate valve rotation positioning at the end of the ‘open’ and ‘close’ stroke. Both stops are located on the cylinder centerline, the optimal osition to maximize travel adjustment and eliminate any detrimental side loading on the travel stops. Adjustable from 82° to 98°. Ingress protection Standard IP66. Optional IP68. Spring designed for safety All spring return models incorporate a ‘man-safe’ spring design that allows the actuator to be safely assembled and disassembled in the field without the need for special tools. The integral tie rods are bored and tapped to provide a means of loading and unloading the spring in a safe andconvenient manner.

DESIGNED WITH A HEART OF STAINLESS STEEL Stainless steel yoke The heart of any scotch yoke actuator is the yoke. S series actuators use 17-4PH stainless for this critical area as standard. The yoke is the mechanism used to convert linear force to torque. This area is most often where the life of the actuator is controlled. Principles of construction Using high quality materials of construction and modern rugged design concepts provides the standard for high quality, low cost valve actuation. The S actuator housings are all machined from 316 stainless steel castings. This produces a rugged, low cost product through reduced machining time and by eliminating wasteful excess material. Any components that rotate or slide during operation, such as the high strength stainless steel output shaft, stainless steel piston rod, stainless steel thrust pin or the stainless steel piston, are all supported by replaceable friction reducing bearings.

FEATURES AND BENEFITS • Innovative stainless steel construction provides superior internal and external corrosion resistance. • Scotch yoke design using precision bearings eliminates dead band in the yoke mechanism, providing the greatest torque output at the beginning and end of stroke. • High strength 17-4PH stainless output shaft transmits torque and gives long service life. • Heat-treated stainless steel thrust pin androllers transfer piston force to yoke to reduce friction for longer life and more efficient torque transmission. • Bi-directional travel stops provide accurate valve rotation adjustment. • PTFE piston bearings, piston rod bushings and output shaft bushings provide longer life, reduce maintenance and require no lubrication. • Universal design position indicator and pointer allows for either parallel or perpendicular mounting. • Stainless steel construction allows proximity switches to be direct-mounted in the actuator housing, eliminating the need to mount bracket and cam assemblies on top. • NAMUR drive slot maintains a compact assembly for accessory-driven components with no couplings necessary. • Available in symmetrical and canted yoke design to suit application. • Spring return model design requires no special tools to disarm springs safely and easily, reducing down time.

Checks Upon Actuator Receipt

• Check that the model, the serial number of the actuator and the technical

data reported on the identification plate correspond with those of order

confirmation (Section 1.2).

• Check that the actuator is equipped with the fittings as provided for by

order confirmation.

• Check that the actuator was not damaged during transportation: if necessary

renovate the painting according to the specification reported on the

order confirmation.

• If the actuator is received already assembled with the valve, its settings have

already been made at the factory.

• If the actuator is delivered separately from the valve, it is necessary to check,

and, if required, to adjust, the settings of the mechanical stops (Section 3.6)

and of microswitches (if any) (Section 3.7).
