2-way Control Valves type L1S0 pages
2-way Control Valves type L1S
Gun Metal, PN 16, DN 15/6 – 20 mm
Characteristics
• Nominal pressure PN 16
k
• Regulating capability kvs > 25
vr
• Single seated and tight closing
• Quadratic characteristic
Applications
Regulating valves type L1S are designed
for regulating low, medium and high
pressure hot water, steam and lubricating
oils.
The valves are installed combined with
temperature or pressure differential
regulators in control systems for heating
of domestic premises, district heating,
industrial processes or marine installations.
Dimensioning
For sizing of control valves and selection
of actuators please see "Quick Choice"
leaet no. 9.0.00.
Design
The valve components - spindle, seats
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.
Pressure/Temperature Diagram
According to DIN 2401
2.2.02-L
GB-1
The valves are single seated and
designed for tight closure.
The leakage rate is less than 0.05% of the
full ow (according to VDI/VDE 2174).
To obtain an approximate, linear transfer
performance, for use in systems with
standard existing heat exchangers and
pumps, the valve characteristic is made
quadratic.
Quality assurance
All valves are manufactured under an ISO
9001 certication, and are pressure and
leakage tested before shipment.
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 or electronic actuators, the valves will close at
rising temperatures. For cooling circuits a
reverse acting valve can be used.
The quadratic characteristic will not
cease, until the ow has dropped below
4% of the full ow.
