REALIZED PROJECTS

UNDERGROUND GAS STORAGE FACILITIES

In October, the production and the first part of the installation of the AT-HD pneumatic control system with stainless steel control box for the underground gas storage tank took place. The entire system was designed and completed for a DN500 PN63 pipe closure and the order also included the installation and connection of the equipment to the customer's technology.

 

 

CENTRIC BUTTERFLY VALVES FOR NATURAL GAS

The delivery of the manually operated valves with a centrically mounted disc and NBR seat took place in October. The butterfly valves were fitted with electromechanical SPDT end sensors in a PCR3SVAZ box from ROTECH for position feedback in the control system. According to customer interest and experience, this is the most popular type in the VALVE CONTROL range of butterfly valves.
