Serving the Water & Waste Water Industry Since 1878IN-PLANT VALVESwww.mh-valve.comM&H Valve is a division of McWane, Inc.AUTOMATIONMORIN ACTUATOR DESCRIPTION:The Morin Actuator is a heavy-duty, quarter-turn scotch yoke piston design available in ductile iron/carbon steel, ductile iron/stainless steel and all stainless steel through 238,000 in. lbs. of torque. It is available as double acting (air-to-air) and spring return (fail-safe). Available accessories include:• solenoid valves, positioners, filter/regulator/lubricators• partial stroke test device• lockout device• jackscrew, hydraulic overrides• AWWA tested per C504 for water or pneumatic serviceWATER INDUSTRY APPLICATIONS• filter galleries• pump control/isolation• submersible• fail-safe isolationElectric motor actuators can be furnished when required. Quarter-turn actuators are available for butterfly and eccentric plug valves. Multi-turn actuators are available for resilient wedges and double disc gate valves.All actuators contain the following standard accessories: a handwheel for manual operation, open and close position limit switches to assure motor shut-off at the ends of travel, open and close torque limit switches to protect the valve from excessive actuator torque and a separate drive nut or coupling. The motors have been designed for high starting torque and long service life. Quarter-turn actuators are furnished with adjustable end of position mechanical stops.Optional accessories include intermediate position limit switches, position feedback devices and integral motor controls. Generally, motor controls consist of reversing starters, control transformer, push buttons, selector switches and indicating lights. For these applications requiring control by an analog signal (usually 4-20 mADC), a positioner can be furnished with motor controls.AUMA SA/GS Quarter-turn Electric ActuatorApplication: Used to operate larger quarter-turn valvesAUMA SG Quarter-turn Electric ActuatorApplication: Used to operate smaller quarter-turn valvesM&H ECCENTRICPLUG VALVESM&H BUTTERFLY VALVES M&H RESILIENT WEDGE(R/W) AND DOUBLEDISC GATE VALVESAVAILABLE END CONNECTIONS & SIZE RANGEFlanged End 3”– 24”M.J. 3”– 24”Grooved 3”– 16” ACCESSORIESFloorstands Electric Motor ActuatorsExtension Stems Cylinder Actuators2” sq.

Size Available End Connections Range Style No. Flanged End 4”-30” 47-02 SUGGESTED SPECIFICATIONS: Flap valves shall be of the circular port design with offset single pivoted hinge. They shall be of the iron body bronze mounted type and furnished with a flanged end. The assembly shall consist of three parts: flap gate, body and hinge pin. The flap gate and body shall be cast iron conforming to ASTM specifications A-126 Class B. The seats and hinge pin shall be furnished of bronze. The flap gate seat ring shall be rolled into a dovetailed groove under pressure to make one inseparable unit. The body seat ring shall be threaded and screwed into place in the body. Both gate and body seat ring faces shall be machined to a smooth finish. The valve shall be constructed with a 10 degree offset from vertical to ensure positive closure. The flange shall be drilled using an ANSI 125 pound template. Valves shall be as furnished by M&H Valve or approved equal. July 2005 / M&H Flap Valves INSTALLATION OPERATION MAINTENANCE M&H VALVE—FLAP VALVES (4”-30”) STYLE 47-02 General Inspect all assemblies at time of delivery for shipping damage and to confirm compliance with order. The valve should be protected from rough handling. Water and debris should not be allowed to collect in valve. I. Installation A. Check that valve end joints are clean B. Remove any material used to restrain the gate during shipment and storage. C. The gate should be checked to insure freedom of motion and proper operation D. When handling the valve, do not use the outside mechanism for lifting. E. Prepare pipe end of manhole as required, and install valve as per appropriate instructions for the specified joint. Bolt holes should straddle the vertical centerline. II. Operations Once properly installed, the valve will operate as pressure conditions dictate. The valve will open under direct pressure to release the outfall fluid and will close to prevent entrance of backwater when the direct pressure is relieved. The flap valve is a 10 degree inclined plane to insure positive seating. III. Maintenance Frequency of inspection should be at least on an annual basis. Joint should be visually inspected for leakage. Raise and lower the flap so pin can be checked for free operation. Troubleshooting: Exercise and lubricate the hinge/shaft pin (*with suitable lubricant) at least annually to assure free operation. Check bronze flap ring and seat ring for freedom from damage. Remove any debris found on inside of valve. Notes: There are no recommended spare parts *Recommend food grade grease similar to Chevron FM Grease EP NLGI 2.
