The Series 3PBV is ideal for mixing or diverting services in industrial, chemical, turf and irrigation, and pool and spa applications, as well as for use with potable water. The valve features a 3-seat design for efficient automation, reinforced TFE seats and EPDM seals for longer life, and an all PVC construction for heavyweight durability at a lightweight cost. Valves also come standard with field selectable NPT or socket process connections.

The 3PBV is an economical automated valve package with either an electric or pneumatic actuator. Electrically actuated models are weatherproof, NEMA 4, powered by standard 115 VAC supply, and are available in either two-position or proportional control. Two-position actuators use the 115 VAC input to drive each of the valve ports open or closed, while the modulating actuator accepts a 4 to 20 mA input for infinite valve positioning. Actuator features include thermal overload protection to withstand stall conditions, visual position indication and a permanently lubricated gear train.

The pneumatic double acting actuator uses an air supply to drive each of the actuator ports. Spring return pneumatic actuators use the air supply to drive the valve stem one direction, and internally loaded springs return the valve to its original position. Also available is the SV3 solenoid valve to electrically switch the supply pressure between the air supply ports. Actuators are constructed of anodized aluminum and are epoxy coated for years of corrosion free service.

LECTRIC ACTUATOR

. BASIC INSTALLATION

. Operate valve manually and place in the open position. (NOTE: ALL ELECTRIC

CTUATORS ARE SHIPPED IN THE OPEN POSITION.)

2. Remove any mechanical stops the valve might have. (DO NOT REMOVE ANY PARTS NECESSARY FOR THE PROPER OPERATION OF THE VALVE, SUCH AS THE PACKING GLAND, PACKING NUT, ETC.)

. Ensure that the actuator output shaft and valve stem are aligned properly. If they

re not, operate the valve manually until they are correct.

. Mount actuator to valve. Do not tighten nuts and bolts at this time.

. Remove actuator cover.

6. Bring power to the actuator. CAUTION: Make sure power is OFF at the main box.

7. Wire the actuator per the diagram attached to the inside of the cover. Special ctuators (those with positioner boards, etc.) will have diagrams enclosed inside

he cover.

. Securely tighten bolts used to mount the actuator to a mounting bracket or

8 directly to the valve mounting pad if it is ISO5211 compliant.

9. Cycle the unit several times and check the open and closed positions of the

valve. Cams are pre-adjusted at the factory; due to the variety of valve designs and types, however, slight adjustments might be required. (SEE II and III).

0. Replace cover and tighten screws.

I. TO SET THE OPEN POSITION

1. Cycle the valve to the open position by applying power to terminals #1 and #2.

The top cam and switch control this position. In the open position, the set screw in the top cam will be accessible.

2. If the valve is not open completely:

. Slightly loosen the 8-32 x 1/4” set screw on the top cam.

. Rotate the cam clockwise (CW) by hand until the switch makes

ontact. Contact is made when a slight click can be heard. By making

c incremental CW movements of the top cam, the valve can be positioned precisely in the desired position. C. When the top cam is set, tighten the set screw securely.

3. If the valve opens too far:

A. Apply power to terminals #1 and #3. This will begin to rotate valve CW. When valve is full open and in the exact position desired, remove power from actuator. B. Loosen the set screw in the top cam. C. Rotate the top cam counterclockwise (CCW) until the switch arm drops off the round portion of the cam onto the flat section. A slight click can be heard as the switch changes state. D. Continue applying power to terminals #1 and #3 until valve is in the desired position.

III. TO SET THE CLOSED POSITION

1. Apply power to terminals #1 and #3 to move the valve toward the closed position.

The bottom cam and switch control the closed position. In the closed position, the set screw in the bottom cam will be accessible.

2. If the valve is not closed completely:

A. Slightly loosen the 8-32 x 1/4” set screw on the bottom cam. B. Rotate the cam counter-clockwise (CCW) by hand until the switch makes contact. Contact is made when a slight click can be heard. By making incremental CCW movements of the bottom cam, the valve can be positioned precisely in the desired position. C. When the top cam is set, tighten the set screw securely.

3. If the valve closes too far:

A. Apply power to terminals #1 and #2. This will begin to rotate valve CCW. When valve is fully closed and in the exact position desired, remove power from actuator. B. Loosen the set screw in the top cam. C. Rotate the top cam clockwise (CW) until the switch arm drops off the round portion of the cam onto the flat section. A slight click can be heard as the switch is no longer making contact with the round part of the cam. D. Continue applying power to terminals #1 and #2 until valve is in the desired position.

IV. MAINTENANCE

Once the actuator has been properly installed, it requires no maintenance. The gear train has been permanently lubricated and in most cases will never be disturbed. In the event it becomes necessary to open the gear box for any reason, however, Shell Darina

#2 grease is recommended for re-lubricating.

age 3

. DUTY CYCLE

ost standard electric actuators are rated for 25% duty cycle at 100% ambient

emperature at the rated torque.

VI. THERMAL OVERLOAD

All actuators are equipped with thermal overload protection to guard the motor against damage due to overheating.

II. MECHANICAL OVERLOAD

ll actuators are designed to withstand stall conditions. It is not recommended to

ubject the unit to repeated stall conditions.

VIII. SPARE PARTS

When ordering parts, please specify:

. Model # B. Serial # C. Part Description

ecommended spare parts include:

R A. Standard actuator: set of cams and switches. B. Actuators w/positioner: set of cams and switches; 1K potentiometer; valve positioner board.

X. NEMA 7 ELECTRIC ACTUATORS

n general, operation and maintenance of a NEMA 7 electric actuator is no different

hat of a NEMA 4 actuator. However, some precautions must be followed:

1. DO NOT under any circumstances remove the cover of the actuator while in a hazardous location. Removal of the cover while in a hazardous location could cause ignition of hazardous atmospheres.

2. DO NOT under any circumstances use a NEMA 7 electric actuator in a azardous location that does not meet the specifications for which the actuator was

esigned.

. Always mount and cycle test the actuator on the valve in a non-hazardous

3 location.

4. When removing the cover, care must be taken not to scratch, scar of deform the

flame path of the cover and base of the actuator, since this will negate the NEMA rating of the enclosure.

5. When replacing the cover on actuators rated for both NEMA 4 & 7, take care that

the gasket is in place to assure proper clearance after the cover is secured. After the cover screws are tightened, the clearance between the cover and the base should be checked. A .002” thick by 1/2” wide feeler gauge is used for this; it must not enter between the two mating faces more than .125".

6. All electrical connections must be in accordance with the specifications for which

the unit is being used.

7. Should the unit ever require maintenance, remove from the hazardous location

before attempting to work on the unit. If the actuator is in a critical application, it is advisable to have a standby unit in stock.

NEUMATIC ACTUATOR

OTE: For optimal operation, 3PBV actuators should be run with a supply of clean,

ubricated air.

SPRING RETURN ACTUATORS

Air to PORT 2 (the right hand port) causes the actuator to turn CCW. Loss of air to PORT 2 causes air to exhaust and the actuator turns CW. This is the FAIL CLOSE

peration.

OUBLE ACTING ACTUATORS

ir to PORT 2 (the right hand port) causes the actuator to turn CCW. Air to PORT

(the left hand port) causes the actuator to turn CW.

DISASSEMBLING STANDARD ACTUATORS IMPORTANT: Before beginning disassembly, ensure that the air supply to the

ctuator has been disconnected, all accessories have been removed and that the

ctuator has been dismounted from the valve.

. Loosen the end cap fasteners (22) with a wrench (size varies depending on

1 actuator model). On the spring return actuator, alternate 3 to 5 turns on each fastener until the springs are completely decompressed. Use caution in removing the cap since the springs are under load until the fasteners are fully extended.

2. Remove the pinion snap ring (10) with a lock ring tool. The indicator (7) may now e removed.

. Turn the pinion shaft (2) CCW until the pistons are at the full end of travel.

isengage the pistons (11) from the pinion. (NOTE: Low pressure air--3 to 5 P.S.I.

D MAXIMUM--might be required to force the pistons completely from the body.) Note the position of the pistons before removing them from the actuator body. The part

umbers of the pistons are located on the side and should be right-side up on an

n actuator with a standard orientation.

4. Remove the pinion through the bottom of the actuator. The actuator is now

completely disassembled. All replacement parts may now be put in. W.E. Anderson recommends that all wear parts (3, 4, 5, 6, 12, 13, 14) be replaced before

eassembly.

REASSEMBLING STANDARD ACTUATORS IMPORTANT: Be sure that the actuator surfaces are free of grit and scratches before reassembling.

1. Apply a light film of grease to all o-rings and the pinion before replacing.

2. Put the pinion (2) back through the actuator with the flats of the pinion shaft

running parallel with the body.

3. When reassembling the actuator, make sure that the piston racks are square to

the actuator body and returned to their original orientation. (NOTE: The normal operation of all PBV pneumatic actuators is FAIL CLOSED. To change the orientation to FAIL OPEN, rotate the racks 180º to create a reverse operation.)

4. When replacing springs in a spring return actuator, ensure that the springs are

replaced in their identical position in the end cap from which they were removed. (NOTE: In some circumstances, you might want to change the standard 80 pound spring set to fit your application and available air pressure. Changing the spring sets on 3PBV pneumatic actuators requires no special tools. Please refer to the spring combination torque chart in our catalog for the inner and outer spring combinations that will allow you to operate with the spring set that you desire.)

4. Seal the end caps with a petroleum lubricant and bolt to actuator body.

5. Check the seal of the actuator by covering seal areas (pinion, end caps) with

soapy water and using low pressure air to the actuator to ensure that no bubbles are produced.
