PNEUMATIC ACTUATORS ПЗ and ПЗН ТУ 38.110475-88

Application

Pneumatic actuators are meant for installation to wedge valves with a live spindle as well as for controlling the process of opening and closing the valves in the remote and local modes. In the distant mode the control is made through the injection of pneumatic and electrical signals to the pneumatic actuator, in the local mode – with the help of control bodies, being on the pneumatic actuator. The pneumatic actuator provides the injection of information signals (pneumatic and electric) about the position of the valve (“OPEN” or “CLOSED”).

ü    Recommended producers of wedge valves:

¨      OJSC “Tyazhpromarmatura”, Aleksin, Tulskaya oblast;

¨      OJSC “IKAR” Kurganskiy zavod truboprovodnoy armatury, Kurgan;

¨      OJSC “Penztyazhpromarmatura”, Penza;

¨      LLC “Yugo-Kamskiy mashinostroitelny zavod”, p. Yugo-Kamskiy Permskoy oblasti;

¨      OJSC “Blagoveshenskiy armaturniy zavod”, Blagoveshensk, Republic of Bashkortostan;

¨      CJSC “ARMAGUS”, Gus-Hrustalniy Vladimirskoy oblasti;

¨      CJSC “GUSAR”, Gus-Hrustalniy Vladimirskoy oblasti;

¨      OJSC “ARMZ”, Angarsk Irkutskoy oblasti;

¨      Valves of other manufacturers – by separate order.

ü      Port area of the valves: DN50, … , DN600.

ü      Conventional pressure of the valves: PN3, … , PN250.

ü      Pneumatic actuators can be installed and operated in explosion hazardous areas of grades 1 and 2 according to GOST Р 51330.13-99 (МЭК 60079-14-96),  also to “The rules electric installations’ arrangement” (ПУЭ) Chapter 7.3 and other directive documents, governing the application of electric equipment in explosion hazardous areas.

Characteristics

  Pneumatic actuators ПЗ are made for providing the following operation modes of the valves (agreed by order): 

– closing the valve at the speed from 3 up to 5 mm/s;

–  increased operation speed (opening and closing time of the valve doesn’t exceed 12 s);

–  controlled process of opening and closing of the valve (according to the law of the control signal change).

  Pneumatic actuators are installed on the valves, made in the performance “with electric drive” and “with manual drive” (agreed by order).

  Pneumatic actuators ПЗН are made for providing the following operation mode of the valves: 

–  increased operation speed (opening and closing time of the valve doesn’t exceed 12 s).
