Intelligent Pressure Balanced Low Noise Globe Control Valve

Intelligent Pressure Balanced Low Noise Globe Control Valve

    The YFL intelligent pressure balanced low noise globe control valve is specially designed to reduce the noise. The SV intelligent pressure balanced globe control valve uses modular design to achieve compact structure. The special symmetric holes on the valve trim are able to reduce the noise and further reduce the pressure in order to prevent flashing and cavitation.

  • Features
  • Specification

  • The modular design makes the YFL single seat globe control valve easy to repair and convenient for maintenance;
  • Single seat with double sealing sides and compressing tightly body ensure excellent seal performance and prolong the service life;
  • The YFL double guided single seat globe control valve has top guided and bottom guided available under the seat makes it suitable for applications require high stability and high pressure;
  • According to bonnet structure, it is classified into standard type, double guided type, control and shut-off type, shut-off type, cool fin type for high temperature application, bellow sealing type, low temperature type for cryogenic service, Jacket type;
  • Equipped with multi-spring pneumatic reinforce actuator makes the valve realize the conversion of normal close and normal open on site easily, the springs can be effectively protected from the corrosion to prolong the service life of actuator.
  • The actuator and the intelligent valve positioner are connected pipeless to strengthen the shock resistance, stability and precision adjustment, to meet precise control of the working conditions.
