RTKZ10 — a series of shut-off valves with forged-welded housings, mounting the oil seal on studs 
RTKZ14 is a series of shut—off valves with forged-welded housings, mounting the stuffing box on folding bolts. Shut-off valve elements are mandatory in various pipeline systems. Installation of special valve mechanisms allows to provide with a high level of tightness the overlap of the movement of liquid or gaseous media.
Where RTKZ10 and RTKZ14 shut-off valves are used
Shut-off valves can be successfully used at production facilities, as well as in pipelines of various communications. A large range of operating temperatures and a variety of body sizes and pipe threads, allows for rapid overlap of the following media:
- Water.
- Steam.
- Oil.
- Petroleum products.
- Natural gas.
RTKZ10 and RTKZ14 valves are made of corrosion-resistant materials, so they can be used in pipelines where aggressive media are moving.
Advantages of shut-off valves RTKZ10 and RTKZ14
The main advantages of RTKZ10 and RTKZ14 are:
- Long service life.
- A large margin of safety.
- High tightness indicators.
The long service life is due to the use of wear-resistant materials. Thanks to this feature, it is possible to ensure reliable sealing of pipeline systems during the entire period of operation of products.
Strength characteristics also depend on the quality of the materials used. The stability of the product body is provided by the stamped housing design. The reliability of operation is also positively influenced by the design feature of the location of the stuffing box. This part of the valve is located directly in the body of the product, which significantly increases the reliability of the system even with intensive use.
Valve control is possible with minimal physical effort. The carefully designed design of the control wheel and the transmission mechanism allows you to achieve a high-class tightness of the shutter without the use of additional devices and mechanisms.
The possibility of manufacturing products of an enlarged design is also an advantage of shut-off valves RTKZ10 and RTKZ14. Various combinations of dimensions of the inlet and outlet pipes make the installation of products easier. The connection to the pipeline may also differ significantly in the type of fasteners used.
