Açıklama
High pressure control valves ANSI 3100 Convalve series high pressure control valves are designed for control of liquids, gases and steam from size DN15 (1/2") up to DN300(12").
Globe valves are a traditional solution for most of the industrial applications thanks to its long-term seat tightness, robust construction, and a wide variety of construction materials. They are preferred mostly for regulation duty due to their proper flow characteristics for this purpose.
Typical control applications include regulation of temperature, pressure, flowrate and level besides many more appliacations found around wherever industrial automation is involved.
Produced in Turkey under ISO 9001:2008 Quality Assurance System, convalve series pneumatic control valves are used in almost all process industries like chemical and petrochemical plants, refineries, power plants, metallurgical mills, paper mills, food and pharmaceutical industries, water treatment, as well as in machinery automation like textile, food and packaging.

  • Leakage Class IV, V or VI acc. to FCI70-2 (IEC 60534-4)
  • Process temperature range between -30... +550°C
  • Provided with pneumatic, electric or hydraulic actuator
  • Choise of analog or digital positioner
  • Optional manual override
  • Manufacturing under quality management system ISO 9001 - 2008 (TUV-SUD)
  • Material and hydraulic tests certificate to EN 10204 3.1 or 3.2
  • Hydraulic tests according to EN 12266-1 and API 598 standards

Maximum working temperature for each pressure class and the relavant maximum working pressure values are shown in "Maximum Body Working Pressure" tables according to ANSI standards.
Cast steel (WCB. WC6, WC9, C12A) valves are mostly suitable for common industrial fluids such as water, condensate, steam and air. WCB bodies can be used up to 425°C. Alloy steels like WC6, WC9 and C12A are recommended for higher temperatures. These alloys include higher molybdenum content, which enhances strength, hardenability, weldability, toughness and corrosion resistance of the material at elevated temperatures.
Stainless steel (F316, CF8M) valves are preffered for either aggresive or corrosive chemical fluids. They are also preferable for corrosive enviroment. Special exotic alloys are also available for more specific applications.
For valve body material selection, the toughest possible working conditions should be considered.
Thrust forces required to dose or open a globe valve depends on valve size and pressure drop across valve (in other words, pressure difference between inlet and outlet of the vatve). Maximum pressure difference values achieved with different actuator models are given in "Shut-Off Pressure (bar) vs. Valve Size Actuator Combination" table.
