The pneumatic actuators ПЗ with the offset control panels are applied by placing the pneumatic actuators in the conditions with the increased dampness (fire wells, buried bunkers).

The binding of the pneumatic actuators ПЗ is made in such a way, that the electrical devices are in normal conditions.

Example of record by ordering the pneumatic actuator ПЗ, having the following characteristics:

– port area of the valve DN100;

– conventional pressure of the valve PN16 (1,6 МПа);

– additional devices’ complete set:

   – one explosion-protected electric pneumatic distributor with the two outputs type – РДВ-4;

   – initial state of the actuator – normally-closed;

   – two explosion-protected electric limit switches type – ВВ-2-01;

   – filter-stabilizer of the air pressure type ФСДВ-10-У1;

   – supply with the compressed air with the pressure from 0,6 up to 0,8 MPa

 Pneumatic actuator ПЗ – 100 – 16 – 05.1.1  ТУ 38.110475-88.

 

Example of record by ordering the pneumatic actuator ПЗ with the controlled process of opening and closing of the valve, having the following characteristics:

– port area of the valve DN100;

– conventional pressure of the valve PN16 (1,6 МПа);

– additional devices’ complete set:

   – electric pneumatic positioner ЭПП‑Ех-2 4-20 mA 400 kPa (600 kPa) 4 У1;

   – two explosion-protected electric limit switches type – ВВ-2-01;

   – filter-stabilizer of the air pressure type ФСДВ-10-У1;

   – supply with the compressed air with the pressure from 0,6 up to 0,8 MPa

 Pneumatic actuator ПЗ – 100 – 16 – 10.1.1  ТУ 38.110475-88.

 

Example of record by ordering the pneumatic actuator ПЗН (for loading racks) for wedge valves with the port area DN 100 and the conventional pressure PN 16

Pneumatic actuator ПЗН – 100 – 16 – 01.0.0  ТУ 38.110475-88.

 

Example of record by ordering the pneumatic actuator ПЗ, providing the time of opening and closing of the valve not exceeding 12 s, having the following characteristics:

– port area of the valve DN100;

– conventional pressure of the valve PN16 (1,6 МПа);

– additional devices’ complete set:

   – one explosion-protected electric pneumatic distributor with the two outputs type – РДВ-4;

   – initial state of the actuator – normally-closed;

   – two explosion-protected electric limit switches type – ВВ-2-01;

   – filter-stabilizer of the air pressure type ФСДВ-10-У1;

   – supply with the compressed air with the pressure from 0,6 up to 0,8 MPa

Pneumatic actuator ПЗ – 100 – 16 – 05.1.1  ТУ 38.110475-88 (increased operating speed).

 

By ordering the pneumatic actuator ПЗ with the elements of the additional devices, different from recommended type, it is necessary to indicate the type of the element, for example –

Pneumatic actuator ПЗ – 100 – 16 – 05.1.1  ТУ 38.110475-88 (limit switches type – ВВ-3-04).
