Qbr Quarter-Turn Valve Electric Actuators

As an alternation product of generation, the model QBR quarter-turn valve electric actuators are newly developed by the model QB of our company. These actuators are suitable for use on butterfly valve, ball-valve and cock valve etc. which are required to turn 90°.  These actuators are featured by small size, light weight, high efficiency, high reliability, high protection capability, low noise and so on. Both operation at site and remote controlling can be carried out. So they have been applied in petroleum and chemical industries, power generating plant, water treatment and papermaking industries.
We can produce the basic model, integral model, explosion-proof model, integral explosion-proof model and integral adjustable model, etc. The basic level of protection and the level of explosion-proof of the products are respectively IP67 and Ex dIIBT4.
    According to the theory of electric control, the following models can be formed:

Basic model: provided with on-site operation switch; course supplied by computer is optional; moment passive contact; output of 4~20mA valve location signal.
Integral model: provided with electric elements, on-site operation switch and field-remote control switch; course supplied by computer is optional; moment passive contact; field-remote controlled circulation state passive contact; output of 4~20mA valve location signal; open phase discrimination and protection device, etc.
Integral adjustable model: provided with electric elements, adjusting plate elements, on-site operation switch and field-remote control switch; course supplied by computer is optional; moment passive contact; field-remote controlled circulation state passive contact; open phase discrimination and protection device, etc.

Description:

Under rated voltage, guarantee value of the ratio of motor blocking current to rated current is, its tolerance is ±20% of the guarantee value.
As the output speed is 2r/min, the output shaft of the products does not self-lock. As a requirement of valve for self-locking is present, note should be taken.
For explosion-proof products, total weight may be increased by 5Kg.
For explosion-proof integral, total weight may be increased by 15Kg.
For integral products, total weight may be increased by 8Kg.
