KQF-B01 factory price electric valve for low pressure steam
switching
Description
The valve body of the electric valve is mainly made of brass, which
is reliable and durable. It is used for the installation between
the nut-connected ball valve and the actuator, and can be quickly
disassembled, which is very convenient and fast. The electric valve
has a precise structure and tight sealing. No leakage, safe to use,
widely used in air conditioning systems, piping systems, water
treatment systems and low pressure steam switching and other
fields.
Features
1. Built-in high quality inching switch, the electric motor is
unenergized upon completion of start and close, so it has long
service life, power saving and specially safe.
2. The shell is high strength flame-retardant engineering plastic,
durable and wearable.
3. Adopt high quality PTFE sealing ring, with special plastic
structure in two terminal, ensure the seal credible and prolong the
service life.
4. B type ball valve driver has inlay control circuit board,control
with one line, matched with three-speed switch, could realize
multi-valves parallel operation as to save temperature controller.

Wiring Diagram
Installation
1. Please read instruction before installing, the installation
shall be performed by technician according to wiring figure.
2. Two-way ball valve has no stipulation on medium flow: three-way
ball valve requires the medium flows from down to left or right.
3. The driver could be installed arbitrarily, but must be above the
valve body, with at least 30mm space for disassemble and
assemble.Keep enough maintenance operation space to round pipe,
equipment an building, but must be the place could be touched by
maintenance personnel through access hole.
4. Prohibit applying force on driver at installation, or it may
damage the driver.
5. Do not apply force on valve handle while disassembling valve
body, or the valve handle will be distort and result in failure.
6. Ordinary ball valve can not match three-speed switch, only with
mechanical or electronic temperature controller; the ball valve
with B type driver could be matched with various temperature
controller.
7. Observe the driver is whether could be started or stopped
credibly at debugging, if the ball rotaries continuously, replace
the driver, or it may shorten the life of seal.
8. Do not warp the driver into the insulating layer.
Notice
In order to avoid the trouble in the running, please wash whole
system before installation, and install 0.5mm(or thinner) filter
device in the system.
Warning
- Cut off the power before installation, maintenance and repairing.
- Cut off the liquid when replace the valve body, open the wind
exhaust valve to release the pressure.
- If the valve is leaked during use, isolate the valve from the
system and exhaust the liquid.
- Choose ordinary driver, one temperature controller could be only
match with one electric control valve, or the factory will be not
responsible for any results.
