Water control
VLSP, pressure independent valve system on/off
Two way pressure independent control and adjustment valve with on/off actuator, shut-off valve and bypass.
DN15/20/25/32. 230V. Used with SIRe Basic and Competent or supplemented with suitable thermostat.
The valve system VLSP consists of the following:
• VKF, valve kit
- TAC, pressure independent regulation and
adjustment valve
- AV, shut off valve
• SD230, actuator on/off 230V
• BPV10, bypass valve
BPV10, by-pass valve
If the valve 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 by-pass valve is DN10 (3/8").
SD230, actuator
The actuator controls the heat supply on/off. In
unpowered mode SD230 is open.
VKF, valve kit
The valve kit is available in four different valve
dimensions, DN15 (1/2”), DN20 (3/4”), DN25 (1”) and
DN32 (1 1/4”).
The valve kit consists of the following:
• TAC, pressure independent regulation and adjustment
valve
• AV, shut off valve
TAC, regulation and adjustment valve
The regulation and adjustment valve 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 with the grey button on the valve.
AV, shut off valve
The shut off valve consists of a ball valve which is either
open or closed and is used to shut off the flow, when
servicing for example.
