SERVICE TEAM WORKS

During the holiday season, planned plant shutdowns were more frequent and this is a period of increased number of calls for service personnel. In August, our specialists carried out regular maintenance and inspection of VALPES electric ball valve assemblies at the ŠKODA AUTO plant in Mladá Boleslav. 18 pcs of VSX series electric actuators for explosion hazardous environments passed the inspection, the fail safe function is guaranteed and the reliability of the backup power supply is guaranteed for the next period.

REALIZED PROJECTS

PNEUMATIC ACTUATORS QUIFER - FAST ACTING

After production and final testing, the order was shipped to a customer in the gas industry in the Russian Federation. QUIFER pneumatic actuator assemblies in FAST ACTING (closing within 1s) will be installed on DN600 size valves. In addition to the standard equipment (end position sensors, solenoid valves and filter/regulating station), the investor required manual control via a hydraulic pump in case of supply air failure. The entire supply meets the requirements for an explosion hazardous area.

PNEUMATIC KNIFE GATE VALVES FOR THE PAPER INDUSTRY

The August order for a domestic paper mill included control valves and one-way knife gate valves with pneumatic actuators, type L20. For the specified working conditions, stainless steel wafer bodies with stainless steel knife and PTFE impregnated synthetic fibre packing were used. Valves of this type allow a full flow of the working fluid with very low pressure loss and their design is suitable for paper mill water but also for bulk media.
