FAQ's:
  • What industries are these pneumatic knife gate valves suitable for?
    They are widely applied in coal preparation and mining for slurry and tailings, sewage treatment for sludge, papermaking and chemical industries for viscous media, and food and pharmaceutical sectors for sanitary-grade systems.
  • What is the difference between single-acting and double-acting pneumatic actuators?
    Single-acting actuators use spring return - the valve closes when air is open and opens when air is cut off (normally open) or vice versa (normally closed). Double-acting actuators use a two-position five-way solenoid valve where air from one port closes the valve and from another port opens it.
  • What sealing options are available for these valves?
    The valves offer both hard sealing (metal-to-metal) and soft sealing options using materials like polyurethane or reinforced polytetrafluoroethylene (PTFE) to suit different media requirements.
  • What are the key performance specifications?
    The valve has a nominal pressure of 1.0Mpa, strength test pressure of 1.5Mpa, seal test pressure of 1.1Mpa, and can handle temperatures up to 425°C with media containing particles, dust, slag and water.
