Flanged Ball valves with reduced bore consists of a housing 1 and side fittings 2, pressing the fluoroplastic seats 5 to the floating ball plug 3. The detachable connection of the fitting 2 with the housing 1 is sealed with a ring 10. The counter-flying spindle 4 is sealed with two fluoroplastic gaskets 6 and 7. The supply of the working medium is to any of the fittings. The crane is switched manually by turning the handle 11 by 90″. The spatial position of the crane on the pipeline is arbitrary. Cranes can be equipped with a position lock.

Incomplete ball valves have a smaller diameter of the outlet compared to the pipeline. This increases the coefficient of hydraulic resistance, and the possibility of rapid overlap reduces the likelihood of a water hammer.
Also, the reduced thickness reduces the load on the locking ball, which significantly increases its service life. By reducing the flow, the force required to stop the movement is reduced. Most devices are equipped with symmetrical passage reduction around the perimeter. This makes it possible to install either side to the direction of movement of the working fluid.
The great advantage of incomplete products is the simplicity of the mechanism and low material consumption. This reduces the weight of the structure and its cost. Thus, these options can be used in plastic pipelines of increased dimensions. Reducing the load on the pipes prolongs their service life and protects the pipes from deformation and mechanical damage.
The main advantages of an incomplete ball valve are:
Such pipe fittings are used on both domestic and industrial systems. They are able to work with liquid and gaseous aggressive substances.
The price of an incomplete ball valve varies depending on a variety of factors, including pressure, diameter and material performance. Additionally, the individual wishes of the customer are taken into account.
You can buy an incomplete crane at a low cost 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 email@example.com
