LKB Automatic or Manual Butterfly Valve

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®.
