Check pipeline valve (DN15-150, PN1.6-4.0 MPa)

Usage:

Check valves are intended to prevent backflow of working medium in the process lines at chemical and oil-refining plants, as well as at pulp-and-paper mills and other production facilities using fluid, gaseous as well as corrosive working media.

Connection to the pipeline for welding, flanged, flanged, coupling, Russian production.
Check pipeline valve is a type of protective pipeline fittings designed to prevent changes in the flow direction of the medium in the process system. Check valves allow the medium to flow in one direction and prevent its movement in the opposite direction, while acting automatically.
Check valves are used:

  • in pipelines where unidirectional movement of the working medium is required.
  • in pipelines with closed circulation of the working medium;
  • in pipelines consisting of several pumps, to exclude mutual influence during their simultaneous operation;
  • in filtration units installed in reversible process lines to ensure the movement of liquid through the filter in only one direction;

The check ball valve consists of the body (1) and two caps (2) bolted together by stud bolts (8) and sealed with joint gaskets (9). When supplying the working medium into the valve (4) the latter is moving within the stop (3) hole compressing the spring (5) and providing the admission of the medium. When cutting off the medium the valve closes under the action of the spring. To provide the leak-proofness of closed valve the latter is sealed with the valve seal (6). To provide valve capacity for work in corrosive media the seat, the spring and the stem are made of corrosion-resistant steel. The working medium can be admitted to the cap according to the pointer on the valve body. Joint to pipeline is welded.

* The valve can be mounted on pipeline in any attitude position required.
* – the flanged and inter-flanged joints are available on the customer’s request.

CHECK PIPELINE VALVE

Check pipeline valves belong to the class of special pipeline fittings installed to prevent a change in the direction of movement of the working medium. They block the return flow of liquid, protecting the equipment from water shocks. Prevent leaks from tanks when the supply pipe is depressurized. At the same time, the work takes place in automatic mode without the use of third-party drives and control systems.

 

General description

 

The check pipe valve is made of stainless or carbon steel and is assembled from the following structural elements:

  • cylindrical housing;
  • two welded pipes, tightened with studs;
  • locking element on the spring;
  • sealing ring.

 

The direction of movement of the medium is indicated by an arrow applied to the surface of the housing.

The diameters of the conditional passage are from 15 to 150 mm. The working pressure is 16, 25 and 40 kg/cm2. Operating temperature from -60°C to +160°C.

In accordance with the technical specification of the customer, the connection to the pipe or equipment can be not only welded, but also flanged.

 

Application environment

This type of shut-off and control valves are installed:

  • in the schemes of strapping pumps when they are connected in parallel;
  • on feeding and filling as automatic feeding devices;
  • on pipelines transporting cold and hot process solutions;
  • on the inlet lines of liquid storage tanks;
  • in fire extinguishing systems and water supply from tanks.

 

It should be borne in mind that such devices have increased hydraulic resistance. Therefore, each installation must be technically justified.

 

COST AND DELIVERY

 

The price of a non-return pipeline valve 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 check valve at an affordable 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 14@fobosarm.ru

Delivery of pipeline valves is carried out by the services of transport companies – Business Lines, PEC. Also, transportation is carried out by rail Zheldorexpedition and other types of delivery with payment for transport services and cargo insurance services by the buyer.
