SINGLE PORTED GLOBE CONTROL VALVES ( TYPE Z1B)

APPLICATION AREA:
Single-ported globe control valves type Z1B are used in automatic and remote control instalations as flow control elements to adjust flow of liquids, steam and gases. Wide range of materials, excellent pressure and temperature parameters, multiple design variants, meeting requirements of various processes, make the valves applicable under the most demanding working conditions in power generation, petroleum chemistry, heating, chemical industry, metallurgy, etc. Versions designated for Western Europe market can be marked BR12.
FEATURES:
  • various materials of valve body and internal parts, adapted to specific working conditions,
  • design provides noise reduction, enhanced resistance to cavitation and flashing, and elimination of choked flow,
  • wide range of nominal pressures, PN10 to CL2500, and flow ratio and control characteristics,
  • reduction in aggressive and toxic media emissions to environment through application of bellow seal bonnets or bonnet packings meeting requirements of TA - LUFT,
  • easy assembly and dismantling of valve internal parts for maintenance and service,
  • high durability and reliability due to application of top-class materials and surface improvement processes (burnishing, stelliting, heat treatment, CrN coatings),
  • possibility of mating with reverse action P/R (column) and P1/R1 (cast yoke) multi-spring actuators, and changing the spring range with no extra parts (keeping the number of springs),
  • possibility of fitting actuators with lateral (P1/R1) or top (P /R) handwheel,
  • possibility of performing diagnostics of “valve-actuator” due to application of smart electro-pneumatic positioners,
  • wide range of electric actuators,
  • special executions for oxygen, hydrogen, gas fuels, low temperature fluids (liquid oxygen, liquid nitrogen), acid gases containing H2S; with heat jacket; for explosive atmospheres as per ATEX Directive 94/23/EC,
  • design and production process meet the requirements of Quality Management System ISO 9001 and Directive 97/23/EC, and regulations of AD2000 Merkblatt, designated for installation on pipelines.
