  • A soft and fatigue-resistant material that mimics heart valves
    Summary Bovine pericardium, a tissue commonly used to make artificial heart valves, fulfills two fundamental mechanical requirements: a low modulus to ensure opening and closing in cyclic pulsatile flow and a high fatigue threshold to prevent crack growth The tissue consists of a soft matrix and crimped fibers
  • Digital hydraulic valves: Advancements in research
    Control valves play an important role in hydraulic systems as they manage hydraulic power by regulating the mechanical power transmitted to an actuator This control can be obtained by managing pressure (using pressure control valves), controlling flow rate (with flow control valves), or directing flow (via directional control valves) [4]
  • Dynamic characteristics measurement of a novel high . . . - ScienceDirect
    Existing high-pressure, large-flow water hydraulic flow valves are critically limited by structural complexity, imprecise control, excessive energy co…
  • A New Way to Pneumatic: Industrial Piezo Electric Valves
    The term A New Way to Pneumatic: Industrial Piezo Electric Valves The term "piezo" refers to a relationship between mechanical deformation and voltage–useful for some sensor processes Recently, the concept has been employed to upgrade pneumatic valves
  • Introduction to Flow Control Valves - Technical Articles
    Control valves manipulate fluid flow rate in industrial applications How do they work, what kinds are there, and what are some specific applications?
  • Valve Positioners | Basic Principles of Control Valves and Actuators . . .
    Read about Valve Positioners (Basic Principles of Control Valves and Actuators) in our free Automation Textbook
  • Biomaterials and biofabrication strategies for tissue-engineered heart . . .
    Heart valve tissue engineering (HVTE) holds the promise of providing living valve replacements with the capacity for growth and regeneration Increasingly, biomaterials and biofabrication technologies that aim to recapitulate essential characteristics of native tissue are being used to tissue engineer heart valves This review first investigates the types of biomaterials used in HVTE and the
  • Control Valve Actuators | Basic Principles of Control Valves and . . .
    The purpose of a control valve actuator is to provide the motive force to operate a valve mechanism Both sliding-stem and rotary control valves enjoy the same selection of actuators: pneumatic, hydraulic, electric motor, and hand (manual) Pneumatic actuators Pneumatic actuators use air pressure pushing against either a flexible diaphragm or a piston to move a valve mechanism The following
  • Materials and manufacturing perspectives in engineering heart valves: a . . .
    With this perspective, we quantitatively compare mechanical properties of various materials that are currently used or proposed for heart valves along with their fabrication processes to identify challenges we face in creating new materials and manufacturing techniques to better mimick the performance of native heart valves
