2-WAY CONTROL VALVES, DN 15/6-20MM, GUN METAL

Applications

Control valves type L1S are designed for regulating low, medium and
high pressure hot water, steam and lubricating oils with thermostats,
pneumatic or electric actuators. The valves are installed combined
with temperature or pressure diff erential regulators in control
systems for heating of domestic premises, district heating, industrial
processes or marine installations. They can also be used in cooling
applications when used with an electric actuator.
The valve components – spindle, seat and cone – are made of stainless
steel. The valve body is made of gun metal RG 5. The thread for the
actuator connection is G1B ISO 228. The valve is single seated. The
leakage rate is less than 0.05% of the full flow (according to VDI/VDE
2174).

FUNCTION

Without the actuator being connected, the valve is held in open
position by means of a spring. With pressure on the spindle the valve
will close. In connection with thermostats, pneumatic or electric
actuators, the valve will close at rising temperatures. For cooling
circuits the valve can be used in conjunction with a reverse acting
electric actuator. Alternatively a reverse acting valve can be used with
our self-acting thermostats. The quadratic characteristic will not
cease, until the flow has dropped below 4% of the full flow

FEATURES

Simple design secures reliable controls and reduces costly downtime.
Location of the pack box in the actuator makes the valve service friendly.
Reliable and secure due to internal parts of stainless steel.
Low leakage rate reduces the risk of overheating

MOUNTING

The valve can be installed with vertical as well as horizontal spindles. For valve temperatures of max. 170 ºC,
the thermostat/ actuator can be fitted below or above the valve. For valve mounted with thermostats in media
temperatures above 170 ºC, a cooling unit has to be applied with connection downwards (please refer to data
sheet for thermostat accessories). For electric actuators a high temperature adaptor must be used (please refer
to datasheets for the electric actuators).
