Valve specialist Schubert & Salzer Control Systems have developed a compact, lightweight, and energy efficient solution with its new type 8028 sliding gate valve.
With a pneumatic 80-millimetre diaphragm actuator and digital positioner, the control valve allows for a low-noise operation. The sliding gate technology used in the type 8028 controls the flow in milliseconds, as two slotted discs are arranged vertically, and the direction of flow slide over each another in a linear movement. The required actuating force is 90% lower than globe valves with the same nominal size at the same differential pressure. It controls media with temperatures from -60 to 350 °C and can be used at ambient temperatures from -30 to 100 °C and the maximum operating pressure is up to 40 bar, depending on nominal size.
