.kyManual or Automatic - its your ChoiceLKB Automatic or Manual Butterfly Valve

.

ConceptLKB is a sanitary automatically or manually operated butterfly valve foruse in stainless steel pipe systems.

Working principleLKB is either remote-controlled by means of an actuator or manuallyoperated by means of a handle.The actuator is made in three standard versions, normally closed (NC),normally open (NO) and air/air activated (A/A).

The actuator is designed so that an axial movement of a piston istransformed into a 90 rotation of a shaft. The torque of the actuator isincreased when the valve disc contacts the seal ring of the butterflyvalve.

The handle for manual operation mechanically locks the valve in itsopen or closed position. The handles for the valve sizes DN125 andDN150, which are designed for locking in two intermediate positions,enable adjusting of the valve, so that the flow rate can be regulated.

Standard designLKB is available in three versions, LKB for ISO tubes, LKB-2 for DINtubes and LKB-F for flange connection.

The valve consists of two valve body halves, valve disc, bushes for thedisc stem and seal ring. LKB-F also consists of two flanges and twoflange seal rings. The valve is assembled by means of screws and nuts.

Two actuator sizes, 85 mm and 133 mm, cover all valve sizes. Theactuator is available in two versions, LKLA and LKLA-T.

The actuator is fitted onto the valve by means of a bracket and screws.(The actuator can also be fitted onto ball valves by means of specialbrackets).

The handle for manual operation is fitted onto the valve by means of acap/block system and a screw.

The valve has welding ends as standard, but LKB and LKB-2 can alsobe supplied with fittings.

OptionsA. Male parts or clamp liners in accordance with required standard.B. ThinkTop for control and indication.*C. Indication unit with micro switches.*D. Indication unit with inductive proximity switches.*E. Indication unit with Hall proximity switches.*F. Explosion proof indication unit with inductive proximity switches.*G. Bracket for actuator. (Also for ball valves).H. Handle with two or four positions (standard on DN125 and DN150).I. Handle for electrical position indication.J. Handle with infinite intermediate positions (not for DN125 and

DN150).K. Multipositioning handle**.L. Lockable Multiposition Handle. Padlock can be mounted as shown

in fig. 3.Note! Padlock is not delivered.

M. Special cap for 90 turned handle position.N. Service tool for actuator.O. Service tool for fitting 25-38 mm (DN25 - DN40) valve discs.

* For further information see Product Catalogue chapter "Control

& Indication".** A padlock can be mounted on the Lockable Multiposition

Handle as shown in the opposite figure.

Note! Padlock is not delivered.

2.3 Safety precautions

Installation

Always read the technical data thoroughly (See chapter 6 Technical data).Always release compressed air after use.Never touch the coupling between the valve body and the actuator if compressed air is supplied to the actuator.

Operation

Always read the technical data thoroughly (See chapter 6 Technical data).Never touch the valve or the pipelines when processing hot liquids or when sterilising.Never touch the coupling between the valve body and the actuator if compressed air is supplied to the actuator.

Always handle lye and acid with great care.

Maintenance

Always observe the technical data thoroughly (See chapter 6 Technical data)Always release compressed air after use.Never service the valve when it is hot.The valve/actuator and the pipelines must never be pressurised when servicing the valve/actuator.

4.2 Troubleshooting

Step 1NOTE!Read the maintenance instructions carefully before replacing wornparts. - See chapter 5.1 General maintenance

Problem Cause/result Repair

- External leakage- Internal leakage by closed valve

(normal wear)

- Worn seal ring- Worn flange seal ring (LKB-F)

Replace the seal ring and the bushes

- External leakage- Internal leakage by closed valve (too

early)

- High pressure- High temperature- Aggressive liquids- Many activations

- Change rubber grade- Change the operating conditions

- Difficult to open/close- Damage to disc connection (high

torque)

Incorrect seal ring (swelling) Replace by a seal ring of a different rubbergrade

Difficult to open/close - 90 displacement of the actuator- Incorrect actuator function (NC,NO)- Worn actuator bearings- Dirt penetration into the actuator

- Fit correctly (see chapter 3.4 Fittingactuator/bracket/handle on the valve(optional extras))

- Change from NC to NO or vice versa- Replace the bearings- Service the actuator

5 Maintenance

Read the instructions carefully. The items refer to the parts list and service kits section.Handle scrap correctly.NC = Normally closed. NO = Normally open. A/A = Air/air activated.

5.6 Dismantling of actuator

Step 11. Press end cap (5) into air cylinder (1).2. Remove retaining ring (6). Use a press!

TD 403-099

Step 2NC/NO actuator:Release the pressure on end cap (5) carefully and remove the endcap.Pay special attention to the warning! TD

-100

Step 3A/A actuator:Remove end cap (5) by hand.Pay special attention to the warning!

TD 403-101

Step 4Remove piston (3) and the springs.NOTE!- The actuator size 133 mm has a caged spring assembly.- The air/air actuator has no springs.

TD 403-271

Step 5Remove connex pin (16) and coupling (17) from rotating cylinderstem (2).

TD 403-119

Step 6Remove rotating cylinder (2) and the remaining internal parts fromair cylinder (1).

TD 403-120

5 Maintenance

Read the instructions carefully.NC = Normally closed. NO = Normally open. A/A = Air/air activated.Lubricate the rubber seals before fitting them. Lubricate the bearings.Clean the piston before assembly.

5.7 Assembly of actuator

Step 1Fit rotating cylinder (2) in air cylinder (1).

TD 403-269

Step 2Fit coupling (17) on rotating cylinder stem (2) and fit connex pin(16).

Fit the connex pincorrectly!

TD 403-270

Step 3Fit the springs in rotating cylinder (2) and fit piston (3) carefully.CAUTION!Fit the piston correctly in relation to the bearings.NOTE!The air/air actuator has no springs.

TD 403-274

Fit correctly!

Step 4A/A actuator:1. Fit end cap (5) sufficiently into air cylinder (1) so that retaining

ring (6) can be fitted in the air cylinder.2. Position the end cap correctly by hand.

Pay special attention to the warning! TD 403-272

Step 51. Fit end cap (5) in air cylinder (1) and press down sufficiently so

that retaining ring (6) can be fitted in the air cylinder.2. Release the pressure on the end cap.

Pay special attention to the warning!

Use a press!

NC/NO actuator

TD 403-273

Step 6Pre-use check:1. Supply compressed air to the actuator.2. Activate the actuator several times to ensure that it operates

smoothly.Pay special attention to the warnings!
