Overview: Solenoid valve is an electromagnetic control of industrial equipment, is used to
Product Specs


Solenoid valve is an electromagnetic control of industrial equipment, is used to control the fluid automation of basic components, are actuators, not limited to hydraulic, pneumatic. Adjust the direction, flow, speed, and other parameters of the media in an industrial control system. Solenoid valves can be equipped with different circuits to achieve the desired control, and control accuracy and flexibility can be guaranteed.


1. Leakage plugging, internal leakage easy to control, the use of safety

Internal and external leakage is a factor that threatens safety. Other self-control valve is usually the stem out, by the electric, pneumatic, hydraulic actuator control spool rotation or movement. This is to solve the long-term action of the valve stem seal outside the leakage problem; only the solenoid valve is the role of electromagnetic force on the seal in the electric control valve magnetic casing casing completed, there is no dynamic seal, The Electric valve torque control is not easy, easy to produce internal leakage, and even pull off the stem head; solenoid valve structure type easy to control the internal leakage, until reduced to zero. Therefore, the use of solenoid valve is particularly safe, especially for corrosive, toxic or high and low temperature media.

2. The system is simple, then access the computer, the price is low

Solenoid valve itself is simple structure, the price is low, compared to other types of actuators such as regulating valve easy to install and maintain. What is more significant is the composition of the automatic control system is much simpler, the price is much lower. As the solenoid valve is the switch signal control, and industrial computer connection is very convenient. In today's popular computer, the price dropped significantly in the era of the advantages of the solenoid valve is even more obvious.

3. Action express, power is small, lightweight appearance

Solenoid valve response time can be as short as several milliseconds, even the pilot solenoid valve can also be controlled in tens of milliseconds. Due to self-loop, than other self-control valve reaction more sensitive. Designed solenoid valve coil power consumption is very low, is energy-saving products; can also be done just trigger the action, automatically keep the valve position, usually not power consumption at all. Solenoid valve small size, both to save space, but also lightweight and beautiful.

4. Adjust the accuracy is limited, the applicable media is limited

Solenoid valve is usually only two states of the switch, the spool can only be in two extreme positions, can not be adjusted continuously, so the adjustment accuracy is also subject to certain restrictions.

Solenoid valve on the media cleanliness has a higher demand, with granular media can not be applied, if the impurities must first filter. In addition, viscous media can not be applied, and the specific product has a relatively narrow medium viscosity range.

5. Variety of models, widely used

Although the inherent lack of solenoid valve, the advantages are still very prominent, so it is designed into a variety of products to meet a variety of different needs, the use of very wide. The progress of the solenoid valve technology is also around how to overcome the inherent deficiencies, how to better play the inherent advantages and start.

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.
