ASCO™ Series D301 Total separation solenoid valves (DRY)
ASCO Series D301 total isolation solenoid valves (DRY) combine the traditional characteristics of strength and reliability, with construction solutions that make them particularly suitable for the control of aggressive and/or no contaminable fluids. These valves are available in 2/2 or 3/2 normally closed, open or universal service versions, plus miniaturized or silent versions with a latching actuator. The diverse range of features make these valves versatile for applications in food, biotechnology, chemical/pharmaceutical, and physiological/medial industries.

  • Direct acting, total isolation solenoid valve: the actuator is totally isolated from the fluid so that the wetted parts are just the body and the diaphragm.
  • Minimum overall dimension. Possibility of disassembling for inspection.
  • Reduced internal volumes: ~0,15 ml (0,15 c.c.).
  • Core duly coated by PTFE(polytetrafluoroethylene) based self lubricating material.
  • Suitable to shut off liquid and gaseous fluids (verify the compatibility of fluid with materials in contact).
