The modern premises are located near the D11 Prague - Hradec Králové motorway. The area of the premises is 170,835 m2, the manufacturing area is 47,773 m2.

The ZPA Company has been in private ownership since 1992. The long-lasting tradition in engineering and electrical engineering, however, goes back to 1894. The original manufacturing program concentrated on production of agricultural machines. For many decades, the ZPA Company has represented a traditional Czech manufacturer of electric actuators and actuators complete with gears and valves. The company occupies an important position in Central Europe, East Europe and several countries of Central Asia.
Actuators from the ZPA Corporation are produced under the trademark MODACT. The equipment is used for controlling various types of valves such as gate-valves, valves, butterfly valves or ball valves even in environment with combustible gases and vapours.
A large number of versions enables broad potentialities of applications of actuators in control circuits of technological processes, e.g. valve control. The ZPA products work in power plants, sugar refineries, water works, waste water plants, heating plants and other facilities.
The manufacturing program includes single or multiple-turn actuators for direct installation on the valve as well as lever, rod and special actuators. The MOA and MOA OC actuators, which operate under extreme conditions in nuclear power plants and hermetic zones, are a speciality.
The modular concept of MODACT actuators, which enable installation of our own gear-boxes, facilitates and unifies a series of various elements in diverse types of actuators, thus ensuring long life, high reliability and broad sphere of application. This is also contributed by several unique designs that have emerged thanks to our own design and development platform, for example a planet gear enabling manual operation, locking of torque switches, low hysteresis and non-linearity of position transmitters, high precision setting of positional and torque switches, etc. Remote control of actuators presents another benefit. A safe operation of actuators is provided by electrical protection IP 55, IP 65 and IP 67.
In 2009, production of blowers, which had been produced by the LUTOS Company, was transferred to Pečky in collaboration with the affiliated company ZPA Engineering. A series manufacture of vertical and horizontal Roots blowers with outputs from 40 to 120,000 m3/h began after building of a modern plant. The plant operates under a KANBAN system.
At present, the company produces several sizes of blowers in special designs that can be used in nuclear engineering. The components are made from special stainless materials.
Most of the components are produced by Division I, other components are made in the affiliated company Lubenecké strojírny. All metal sheet structures are made by Division II, which also provides finishing processes.

Actuators:

Single-turn actuators - used for controlling valves with an operational range of 0-360° such as ball valves, butterfly valves or three-way ball valves - control torque 16 – 1,000 Nm
Multiple-turn actuators - used for controlling valves with multiple-turn movement, e.g. gate-valves, slide-gates and valves - control torque 16 – 50,000 Nm
Lever actuators - used for controlling valves with an operation range of 0-120°, e.g. louvered flaps, butterfly valves controlled by a rod, valves in a shut-off and control mode - control torque 16 – 4,000 Nm
Rod actuators - used for controlling valves with rod movement, e.g. butterfly and control valves - shut-off force 5,000 – 63,000
Special actuators - used for controlling valves in the I and II zones of nuclear power plants, e.g. ball valves, butterfly valves, gate-valves and valves - control torque 16 – 4,000 Nm
