Product Specs

Overview:

Pneumatic butterfly valve is composed of pneumatic actuators and butterfly valves. Pneumatic butterfly valve is a circular disc with the stem to do the opening and closing, in order to achieve the action of the pneumatic valve to do the main use of the truncated valve can also be designed to have a regulation or segment valve and adjust the function of the current butterfly valve The use of the diameter of the pipeline more and more.


Features:

1. Compact and easy, easy to disassemble and repair, and can be installed in any location.

2. Simple structure, compact, small operating torque, 90 ° turn open quickly.

3. Flow characteristics of a straight line, good regulatory performance.

4. The connection between the butterfly plate and the stem is done with a pinless construction to overcome possible leaks.

5. butterfly plate cylindrical spherical shape, improve the sealing performance and extend the service life of the valve, with pressure to open or close more than 50,000 times to maintain zero leakage.

6. Seals can be replaced, and the seal is reliable to achieve two-way seal.

7. Butterfly plate can be sprayed according to user requirements, such as nylon or polytetrafluoroethane.

8. The valve can be designed for flange connection and clip connection.

9. Drive mode can choose manual, electric or pneumatic.

Features and Benefits

  • Compact Design
    The Luobai rack & pinion pneumatic actuator produces linear torque output in a compact design utilizing the same body and end caps for double-acting and spring-return units.
  • Degree of Travel
    The standard angle of rotation is 90°. Luobai actuators feature dual travel stops that provide ± 10° stroke rotation on both the opening and closing phases of the actuator stroke. 110° of travel in a standard 90° actuator!
  • Honed Bore for High Cycle Life
    Extruded aluminum body is internally machined and honed to exact specifications. Honing prevents dry spots from forming within the actuator bore and therefore eliminates premature seal failure—a critical aspect to long cycle-life. All internal and external surfaces are hard anodized for corrosion resistance, with all units permanently lubricated at the factory.
  • High-Cycle Bearings
    Shaft bearings isolate the pinion gear from the housing and support the shaft for high-cycle applications. Many competitive manufacturers do not provide this critical feature.
  • High Cycle-Life Wear Pads
    Pistons incorporate double wear pads (skates) to separate the rack from the actuator wall and serve as both guide and wear bearings.
  • Rugged Tooth Design
    The pinion teeth are engaged the full length and stroke of the piston, and designed for the toughest flow conditions. The pinion height allows manual override without needing to remove the indicator.
  • Multiple Output Shafts
    The female pinion drive is standard with a double-square output drive, and optional with a double-D drive, keyed drive and designs to meet your specific requirements.
  • Namur Mounting
    Namur VDI/VDE 3845 and ISO 5211 dimensions on all sizes. No special blocks are required to mount solenoid valves, limit switches or positioners.
  • High Visibility Beacon
    External open/close indicator as standard, available for all rotations.
  • Safe Preloaded Spring Cartridges
    Epoxy-coated special steel springs are pre-loaded with non- metallic materials. The stainless steel end-cap fasteners are extra-long to allow for spring relaxation. All parts are corrosion-resistant.
  • Alternate Operating Media
    Air pressure operation from 40 to 150 psi (2 to 10 Bar). Water, nitrogen and compatible hydraulic fluids may also be used to power the actuator.
  • Stainless Steel Fasteners
    All external fasteners are corrosion-resistant stainless steel.
  • Optional Accessories
    Luobai offers a wide range of adapters for many different types of valves—including butterfly valves, ball valves and plug valves—as well as a variety of pneumatic and electric automation accessories suitable for diverse industrial environments.
  • Quality Assurance
    100% of all units are factory pressure and leak tested, and individually boxed for shipment.
  • Traceability
    All units are externally marked with a progressive traceable serial number.
  • Best Warranty In The Industry
    Luobai products are covered by our unlimited cycle-life warranty. Contact your local distributor or sales representative for more details.
