QT Series Electric Explosion-proof Actuators

BENEFITS OF FLEYENDA FLOW

  • Fast Delivery: Standard products in stock
  • ODM Service is Available
  • One-stop Solution: Full set of accessories for the option to improve your working efficiency
  • Quality Assurance: CE, ISO9000 certification. Strict IPQC & QC to make sure the high-quality actuator and valve
  • Cost-effective: Long service life and lower maintenance expenses. Simple maintenance reduces the potential of project delays.
  • Safety: Reduces the likelihood of accumulation persisting in pipes, resulting in pipe bursts.
  • Site Requirements: Butterfly valves are smaller in size and need less site area.

ADVANTAGES OF PRODUCTS

  • Construct: Simpler, lighter, and more compact structure.
  • Medium: Convey muck and gather the least amount of liquid at the pipeline's mouth
  • Maintenance: A 2-section valve stem is pinless. Maintenance and disassembly are easy.
  • Sealing: PTFE, The sealing substance is corrosion and age-resistant
  • Actuator: On-off type, adjustable type, intelligent type can be optional
  • Fast and Responsive: Quick opening and closing functions
  • Low and High-temperature Resistance: PDEM: -10℃ ~120℃ / PTFE: -30℃ ~180℃

QT ELECTRIC EXPLOSION-PROOF ACTUATOR FEATURES

  • Housing: The housing is made of hard aluminum alloy, with anodic oxidation treatment and polyester powder coating, contributing to its strong corrosion resistance. It has a protection class of IP67, NEMA4 and 6, and is also optional for IP68 and the explosion-proof type.
  • Motor: The fully enclosed squirrel-cage motor has a small size, a large torque and a small inertia force, with an insulation class F and a built-in thermal protection switch to prevent damage to the motor caused by overheating.
  • Indicator: The indicator is mounted on the central shaft and used to observe the valve position. The mirror adopts a convex lens design with no water accumulation, thus easier for observation.
  • Limit Switch: Mechanical + electronic limit. The mechanical limit screw is adjustable, being safe and reliable. The electronic limit switch is controlled by the cam mechanism, and the position can be set accurately and easily just by means of adjusting the mechanism simply, without battery support (All micro-switch contacts are silver contacts).

BUTTERFLY VALVE FEATURES

  • Compact: The structure is simple and compact, the operating torque is small, and the 90° rotation opens quickly
  • Functions: It can be used to cut off the medium and adjust the flow of the medium
  • Coating: The butterfly plate can be spray-coated according to user requirements, such as nylon or polytetrafluoroethylene
  • Adjustable: The flow characteristics tend to be linear and the adjustment performance is good
  • Stem Seal: Not easily deformed, avoiding the usual stem leakage
  • Sealing: The seals are replaceable and the sealing is reliable and achieves two-way sealing
