Single-ported globe control valves type Z1B-M

Applied in automatic and remote control installations as flow control elements to adjust flow of liquids, steam and gases.

A wide range of material executions, high parameters in the range of pressures and operating temperatures, numerous design variants adapted to the requirements of the technological process allow these valves to be used for the most demanding conditions in power engineering, petrochemical, heating, chemical industry, metallurgy etc. In Europe they are known as BR12B.

We can adjust the control valve to match your individual needs.

  • various materials of valve body cast and internal parts, adapted to specific working conditions
  • constructional designs limiting the level of generated noise, increasing resistance to cavitation and flashing, enabling elimination of throttled flow
  • wide range of nominal pressures from PN10 to CL2500, as well as flow ratios and control characteristics
  • reduction in aggressive and toxic media emissions to the environment through application of bellow seal bonnets or bonnet packings meeting the 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 matching with reversible action P1/R1 (with cast yoke) and P/R (column) multi-spring actuators and changing the spring range with no extra parts (keeping the number of springs)
  • possibility of equipping the actuators with a side (up to P1/R1) or top (up to P/R) manual drive
  • possibility of performing diagnostics of “valve-actuator” system, due to application of smart electro-pneumatic positioners
  • wide range of electric drives
  • - possibility of special executions: for oxygen, hydrogen, low temperature mediums (liquid oxygen, liquid nitrogen), acid gases containing H2S; with heating jacket; for explosive atmospheres as per 94/9/EC – ATEX
  • the 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
  • 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)
We can adjust the control valve to match your individual needs. In such cases, please contact our technical support specialist.
