    • What Makes the One-Way Check Valve a Game-Changer
      Company News
      One-way check valves are mechanical devices designed to allow fluid flow in one direction while preventing backflow. They are typically composed of a valve body and a movable element, such as a hinged flap, ball, or diaphragm. The valve opens when the pressure on the inlet side exceeds the pressure on the outlet side, allowing fluid to flow. However, when the flow tries to reverse, the movable element closes, creating a tight seal that blocks backflow.

    • What Is the Role of a Solenoid Valve in a Refrigeration System?
      Company News
      A solenoid valve is a control mechanism for regulating refrigerant flow in a refrigeration system. Located within the refrigerant line, it acts as a gatekeeper, opening or closing to allow or block the passage of refrigerant. By controlling the flow, solenoid valves help maintain the desired temperature, pressure, and refrigerant distribution throughout the system.
