One-piece shut-off valve which is seated centrally and designed to favor
flow. It is tight closing in both flow directions. The seat seal is
vulcanized on a carrier ring and exchangeable.
The shut-off valve is pneumatically double- or single-actuated or can be
opened or closed using spring force. It has a flange connection for clamping
between flanges acc. to DIN 2501.
The pneumatic control of the actuator is optionally carried out with a
directly mounted or separate 5/2 or 3/2 way valve which can be operated
electrically, pneumatically or manually.
Neutral gases or liquids with a viscosity of up to 120 mm²/s can be used as
flow media. It should be noted that media that increase the actuation torque
require a different actuator assignment. In case of aggressive media, please
refer to the material resistance tables ZXWBT343.
PRODUCT FEATURES
Shut-off valves of type PZR have the following special features as standard:
Automatic valve in brass with floating precision ball. The valve is pneumatically (double or singleacting) operated and is characterised by long service life and high operational safety.
CHARACTERISTIC FEATURESThe 2/2-way automatic butterfly valve of PZR/EZR type is a combination of the following components:
and one of the following rotary actuators (according to order):
PKI (PNEUMATIC)The valve is operated pneumatically (double- and single-acting) or electrically and is characterized by a long service life and high operational safety.
One-piece, blow-out safe, flow-fitting form, sealed-off and centric embedded butterfly-valve. The automated butterfly-valve is pneumatically operated (double- or single-acting).

The actuator series agturn with the extended rotating angles 120°/135°/180° can be used for valves which have a working range beyond the standard 90° opening angle, e.g. 3-way valves as well as pipe diverters and hinged boxes.
With our variable adjustment options, any desired rotating angle between 90° and 180° can be precisely adjusted to the individual valve. This reduces the number of variants, increases availability in the application, and reduces stock-keeping.
actubar is the latest generation in our range of pneumatic actuators. Externally unmistakable and technically unique, the actubar offers new advantages and uses. In this version, the actubar has been adapted to the special requirements of process engineering in chemical plants
Technically speaking, actubar is the main component in the valve control system bar-vacontrol, a modular, intelligent system for monitoring and regulating automatic valves.
Working together with our directly-mountable system components bar-positurn2 or bar-posiswitch, actubar regulates quarter-turn valves economically and effectively.
