PMK2/EMK2-IM-DE-B-EN-01-23 Rev.0

3.  Product description

The 3/2-way automatic valve of PMK2/ EMK2 
type is a combination of the following com-
ponents:

• 

3/2-way ball valve of MK2 type made of 
brass, with floating precision ball

and one of the following rotary actuators 
(according to order):

PKI (pneumatic)

• 

agturn Type GD-032 till 040 and  
Type GD/GS-052 till 400

• 

actubar Type AD-001 and  
Type AD/AS-002 till 1200

EKI (electric)

• 

electric rotary actuator of company 
Valpes

The valve is operated pneumatically (dou-
ble- and single-acting) or electrically and is 
characterized by a long service life and high 
operational safety.

Product features:

• 

Full passage

• 

Maintenance-free

• 

Optionally available with end position 
feedback, position controllers and so-
lenoid valves (only for pneumatic rotary 
actuators)

• 

Anti-blowout spindle

• 

Usage also with vacuum and high flow 
velocities

• 

Alternatively also can be delivered with 
hand lever or gearbox

3.1  Ball valve

The 3/2way ball valve of MK2 type is intended for installation in piping systems. Its function 
is to shut off or regulate a medium in pipelines. 

3.2  Rotary actuator

The rotary actuator is used for the automatic actuation of industrial valves continuously 
moving between the end positions.
