FLE-QT-W-B Wafer 4 inch Explosion Proof Motorized Butterfly Valve

The FLE-QT-W-B can be controlled by inputting switch signals or control signals (4~20mA or 1~5VDC) and a single-phase power supply. 

The explosion proof motorized butterfly valve is characterized by its strong functionality, small size, lightweight, reliable performance, simple matching, and high flow capacity. It is especially suitable for various liquids, gases, steam, and situations where the medium is viscous, contains particles, or has fibrous properties. 

Currently, this explosion-proof electric control butterfly valve is widely used in industrial automation control systems in industries such as food, environmental protection, light industry, petroleum, papermaking, chemical, teaching and research equipment, and power.

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

  • Butterfly valve: Wafer, Flanged Type, Lug
  • Material: PVC
  • Standard: GB/ANSI/JIS/DIN
  • Special Requirements: High pressure, high temperature, strong corrosion can be customized
  • Stem Seal: Not easily deformed, avoiding the usual stem leakage
  • Automated Centering Function: Achieve the minimal interference fit between the butterfly plate and the valve seat
