  • Features
  • Specification

  • The YFL adjustable choke valve uses the stem tip driven by the rotating hand wheel to adjust the effective area available for the flow to control the production rate;
  • The YFL positive choke valve uses flow beans in different orifice diameters that can be changed to adjust the effective area available for the flow to control the production rate;
  • Structure type: needle type, barrel type, cage type, orifice type and wedge type;
  • The YFL H2 adjustable choke valve has externally controlled indicator showing orifice size in the increment of 1/16th inch;
  • All pressure-containing parts are made from alloy steels for enough tensile strength in order to ensure the safety and reliability at rated working pressure;
  • Choke beans are made from hard alloys for good wear and erosion resistance;
  • The YFL hydraulic choke valve uses the valve core which can be lifted and lowered to adjust the effective area available for the flow.
