A dosing valve is a proportional valve that sets how much material passes through a line, most often at bunker and silo outlets. Our flow control gate opens anywhere between 0° and 90° on a 4-20 mA signal and reports its position back, so it can feed a rotary packer, a bulk loading point, a flowmeter or a belt weigher at a controlled rate.
Dosing means adding a new substance to raw material. The dosing flap is a part used in many different places and control units according to its usage and purpose.
Packaging machine factories are another place where the dosing flap is used, and bulk loading is a third. These valves are needed to meet the energy needs in a much more efficient and qualified way. The valve flap is preferred in weighing feeding devices as it offers various sizes.
Where is the dosing system used?
The dosing system can be used for any purpose in any facility. This flap controls the passage of any fluid. If a substance other than the original raw material is to be added during production, a dosing process is required, and this process is done with the help of a flap.
Dosing means determining the amount of the material passing through. Determining this is a very sensitive and important process. It requires a very fine measurement and evaluation, which is why the function of the valve matters so much.
All kinds of hot and cold water lines, different pipelines, water treatment plants, seawater applications and power plants are among the areas where these valves are used. In addition, the valves decide which substances are allowed to pass through the production facilities, so their function is a sensitive and delicate one.
Which materials are dosing valves made of?
The valve can be made of stainless steel, forged steel or ductile iron, depending on the place of use. This material can be changed according to the work to be done, the temperature and the pressure of the environment. The body and drum of our flow control gate are of steel construction.
Advantages of a dosing valve
A dosing flap gives a valve several advantages, although not every valve has one. The first is that the damper can regulate the airflow. Another is that it ensures that the link does not bounce. A throttle is generally designed with a double shaft, which keeps the pressure to a minimum, and low pressure is a further advantage of these valves.
On our gate, the aperture opens linearly and gives a reliable dust-tight shut-off. A 4-20 mA feedback signal reports the position, and 2×3 wire SPDT microswitches mark it. The gate closes when power or air fails, and its cassette-type sealing is exchangeable for easy maintenance. A lever allows manual adjustment.
We drive the gate pneumatically or with a gear motor. For pneumatic types we use Kinetrol pneumatic actuators and positioners; Mor Endüstri is the official distributor of Kinetrol Ltd in Turkey. We build each gate in the model and size its drive type, roller type, application and capacity call for.
At a silo outlet that feeds a packer or a belt weigher, the valve should be set and read back by signal: our flow control gate positions within 0° to 90° on 4-20 mA and closes when power or air fails.
