LKB Automatic or Manual Butterfly Valve

LKB-F butterfly valve with LKLA actuator

LKB butterfly valve with handle 1.1

Application

LKB is a sanitary automatically or manually operated butterfly valve for

use in stainless steel pipe systems.

Working principle

LKB is either remote-controlled by means of an actuator or manually

operated 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 is

transformed into a 90° rotation of a shaft. The torque of the actuator is

increased when the valve disc contacts the seal ring of the butterfly

valve.

The handle for manual operation mechanically locks the valve in its

open or closed position.

The handles for the valve sizes DN125 and DN150, which are designed

for locking in two intermediate positions, enables adjusting of the

valve, so that the flow rate can be regulated.

Standard design

LKB is available in three versions, LKB for ISO tubes, LKB-2 for DIN

tubes and LKB-F for flange connection.

The valve consists of two valve body halves, valve disc, bushes for the

disc stem and seal ring. LKB-F also consists of two flanges and two

flange seal rings. The valve is assembled by means of screws and nuts.

Two actuator sizes, ø85mm and ø133mm, cover all valve sizes. The

actuator 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 special

brackets).

The handle for manual operation is fitted onto the valve by means of a

cap/block system and a screw.

The valve has welding ends as standard, but LKB and LKB-2 can also

be supplied with fittings.

Control Equipment

Control and indication is possible in connection with the

remote-controlled LKB valve. See "Options".

LKLA-T can be fitted with ThinkTop®.

Seal Qualities

PFA:

PFA is a bonded seal in the PTFE family consisting of an EPDM seal with an outside PFA liner. The chemical resistance of PFA is very similar to PTFE,

butoppositetothosePFAisthermoplasticandhasminimalporosity. The seal has high mechanical strength which makes it a perfect choice when

dealing with abrasive products. Furthermore, the design of the PFA seal minimizes the risk of worn seal. Another advantage of the PFA seal is that the

service intervals are prolonged due to a longer lifetime for the seal. The maximal temperature for the PFA seal is 90°C (194°F).

The seal is available in the following sizes: ISO:38, 51, 63.5, 76.1, 101.6 and DIN: 40, 50, 65, 80, 100.

The PFA seal rings fit the LKB-F sizes for ISO and are available as spare. The flange seals are not available in PFA, please select available rubber quality.

EPDM:

The EPDM seal is mechanically strong and normally resistant to ozone and other strong oxidizers, animal and vegetable fats, polar solvents, Acids

and bases, water and aqueous solutions.

The seal is available in all sizes.

Silicone:

Normally resistant to ozone, other strong oxidizers and strong bases. The seal is available in all sizes.

FPM:

Normally resistant to ozone and other oxidizers, hydrocarbons in general, oils, lubricants and greases.

The seal is available in all sizes.

HNBR:

Mechanically strong and normally resistant to ozone and strong oxidizers, animal and vegetable fats, nonpolar solvents, oils and lubricants, water

and aqueous solutions.

The flange seals are not available in HNBR, please select available rubber quality.

For further information on Product- and Chemical Resistance of Flexible Rubber Materials, please see PD sheet 65036.
