VLSP, pressure independent
valve kit on/off
Two way pressure independent control and
adjustment valve with on/off actuator, shut-off
valve and bypass. DN15/20/25/32. 230V.
The valve set consists of the following:
• TAC, pressure independent regulation and
adjustment valve
• SD230, actuator on/off 230V
• AV, shut off valve
• BPV10, bypass valve
The shut off valve (AV) consists of a ball valve
which is either open or closed and is used to
shut off the flow, when servicing for example.
The regulation and adjustment valve (TAC)
can be used to finely adjust or shut off the
water flow manually. TAC is independent
of the available differential pressure, which
contributes to stable and accurate regulation
(ensures the correct flow to the heater even if
the differential pressure in the rest of the pipe
system changes). The water flow is set using
the gray adjustment knob on the valve
If the valve (TAC) is closed, a low flow
passes through the by-pass valve (BPV10) so
that there is always hot water in the water
coil. This is to provide quick heat supply
when a door is opened but also to provide a
degree of frost protection.
The actuator (SD) controls the heat supply
on/off. In unpowered mode SD230 is open.
The valve set is available in 4 different
valve dimensions, DN15 (1/2"), DN20 (3/4"),
DN25 (1") and DN32 (1 1/4"). The by-pass
valve is DN10 (3/8").
Used with SIRe Basic and Competent or
supplemented with suitable thermostat.

Material
AMETAL® is a dezincification resistant alloy.
Media:
Water or neutral fluids, water-glycol
mixtures.
Flow range
:
The flow (q
max
) can be set within the
range:
DN 15 LF: 44-245 l/h
DN 15 NF:88-470 l/h
DN 20: 210-1150 l/h
DN 25: 370-2150 l/h
DN 32: 800 - 3700 l/h
q
max
= l/h at each setting and fully open
valve plug.
Differential pressure (DpV):
Max. differential pressure (DpV
max
):
400 kPa = 4 bar
Min. differential pressure (DpV
min
):
DN15, DN20 = 15 kPa = 0,15 bar
DN25, DN32 = 23 kPa = 0,23 bar
(Valid for position 10, fully open. Other
positions will require lower differential
pressure.)
DpV
max
= The maximum allowed pressure
drop over the valve, to fulfi ll all stated
performances.
DpV
min
= The minimum recommended
pressure drop over the valve, for proper
differential pressure control.
