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.

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.
