  • Valve Actuator Opportunities with Shale Gas in the U.S. in 2014
    Domestic Natural Gas Liquids (NGLs) production is projected to increase by more than 45% by 2040. What are the resulting opportunities for valve actuator manufacturers?
  • Household Gas Valve Electric Actuator PMDC Motor
    In order to eliminate the fire safety hazard caused by gas leakage, an intelligent actuator that integrates the functions of gas leakage detection, signal transmission, control of motor start, and automatic closing of gas valve came into being.
  • Motor Selection for HVAC Gas Valve Actuators
    The purpose of this paper is to highlight and compare motor technologies available for the actuation of gas valves used in heating, ventilation and air conditioning (HVAC) systems. HVAC systems include low cost, electronically controlled valves for fluid flow modulation and shut-off purposes
  • Motion System Options for HVAC Gas Valve Actuators
    Some control valves are opened and closed manually at the valve stem, while electronic valves incorporate an actuator to move the stem with control from a motor and drive system. Designers have three motor types to choose from, depending on the application requirements. Here's a summary
  • Variable Leak Valves: Fine Leak
    All-metal MLV series leak valves are specifically designed to control gas admission into ultrahigh vacuum systems. They are manually actuated and ideally suited for handling hot or corrosive gases commonly used in demanding research environments. The valve body is constructed of type 304 stainless
  • Variable Leak Valves: Precision Leak
    All-metal ULV series precision ultrahigh vacuum leak valves are designed to control gas admission into high and ultrahigh vacuum systems. They are manually actuated via a cantilever arm fitted with extra-fine pitch threads for precise adjustment. They are ideally suited for handling hot
  • Different Types of Pressure Control Valves
    , which depends on an external signal for its actuation, which normally comes from a digital pressure regulator. In certain applications, like ventilators and anesthesia machines, the flow must be consistent at all times. Variations in the flow of gases can lead to serious injury or death. That's why
  • Valve Actuators and Positioners Go Digital
    Fieldbus is the name of a family of industrial computer network protocols used for real-time distributed control, standardized as IEC 61158. Advanced digital fieldbus technology has been successfully used in oil and gas, petrochemical, pulp and paper, and other industries. This technology has also
