Parker Series BD Servo Valves

Parker BD15 Servo valveBD Series Servo Valves feature a single source pilot design to best protect your system against “hard-over” failures. An internal filter mechanism makes the BD Series servo valves highly tolerant to contamination and easy to maintain. The Parker Series BD Servovalve provides high resolution in the control of position, velocity and force in motion control applications. When used in conjunction with Series BD90/95 and BD101 servo amplifiers or a motion controller, Series BD valves will provide accurate control of rotary and linear actuators. Some of the BD Series features include:

  • Rugged reliable trouble-free operation
  • Reduced contaminant sensitivity
  • Linear flow gain characteristics
  • Intrinsically safe model available
  • Explosion proof model available

Servovalve Solution for Gas Turbines

Plant operators have relied on Parker valves to provide control solutions for gas and liquid fuel turbines for many years. The Series BD Servovalve is an example of a high performance Parker valve designed to meet the critical performance requirements of the industrial market.

Manifold Mounted Servovalves

Servovalves are used in high precision applications that also require operating power of 200mW or less. These conditions are often found in process plant, power generation, mining, oil and gas, and simulation applications. The torque-motor pilot design of Parker Servovalves incorporates mechanical feedback for high response.

In addition, Parker Servovalves meet ATEX, CSA, and Factory Mutual requirements and are therefore available for applications in hazardous conditions. Parker Servovalves can directly replace competitive models in existing applications.
