  1. Internal structure optimized for a compact size with a larger flow (orifice diameter of 4 mm) than conventional valves.
  2. Power consumption reduced by approximately 40% compared to equivalent models by other manufactures.
  3. Operating pressure range of -90 to 300 kPa for both IN and OUT ports, enabling the valve to operate properly when a pump reverses its flow.
  4. Compatible with fluid temperatures of up to 95??C, making it applicable in dialysis machine flushing processes. Wetted materials are also resistant to washing liquids such as sodium hypochlorite.
  5. Coil covered by a case, eliminating concerns of liquids splashing on the valve during maintenance.
  6. Different types of??port connections available, including O-ring types, which can be mounted directly on a balance chamber.
