as shut-off devices with remote control and are designed to automate the control of technological processes in many industries.
Pneumatically actuated ball valves FB39 are intended to be fitted as automated devices in the process lines chemical and oil-refining plants, at pulp-and-paper mills and other production facilities using fluid, gaseous as well as corrosive working media. Standard industrial and explosion-proof versions are available. Distinctive features of these valves are reliability and mean time to failure.

The valve consists of the following principal components: the body (1), the caps (2), the ball (3), and the stem (4). The valve body (1) and the ball (3) are sealed with ball seats (5) and joint gaskets (7) compressed by the bolting of the caps by stud bolts (12). The stem (5) is sealed with stem packing (8) and stem seal (9). The pneumatic actuator consists of the housing and two pistons, which are seated at the ends of the rack. The ratchet latch planted on the shaft meshes with the rack. When supplying compressed air into the actuator housing the pistons turn the ratchet latch and the shaft. The torque passes on the stem by the adaptor, and the latter turns the ball. The top of the pneumatic actuator accommodates the electro pneumatic regulator. The valve can be mounted on the pipeline in any attitude position required.

The dimensions and standard size of the drive are conditional, because they are specified for a two-way drive, PN16 and a compressed air pressure of 5.6 bar. For other PN and compressed air pressures other than 5.6 bar, as well as for a single-acting drive, the dimensions and size of the drive will differ. Also, pneumatic actuators can be equipped with a manual doubler, a pneumatic distributor, a filter reducer, a positioner, shaft position sensors, which leads to significant differences in design and dimensions from those indicated in the figure. In addition to flanged valves, pneumatic drive can be equipped with coupling and welded cranes, the dimensions of which are indicated in the relevant sections of the catalog.
When ordering, it is mandatory to fill out a questionnaire,

The ball valve with pneumatic drive belongs to the category of remotely controlled shut-off and control valves. It is widely used in automated process control systems of industrial enterprises. An important feature of the design is the presence of a pneumatic drive. It is able to create a significant force on the rotary rod with more precise and smooth regulation.
Structurally, the valve with a pneumatic actuator of the FB39.012 series is an inter-flange locking device, which includes two clamping nozzles and a pneumatic actuator. Main assembly parts:
The outer metal surface of all the constituent elements is painted with polymer paint on the ground.
The case has 3 versions depending on the steel grade used:
Rotary spindle made of 14X17N2T alloy.
When submitting an application for the purchase of a ball valve with a pneumatic actuator, it is necessary to fill out a questionnaire in which it is indicated:
The questionnaire form is provided on the website. Additional information by phone.
The price of a ball valve with a pneumatic actuator varies depending on many factors, including the design of pressure, diameter and material. Additionally, the individual wishes of the customer are taken into account.
You can buy a ball valve at a low price in JSC “RC “Fobos” by making an application by phone 8 (800) 700-62-60 (Moscow and all Russia) or using the services of regional managers, as well as by e-mail firstname.lastname@example.org
