The air cylinders has the field of round cylinders and tie rods well and truly covered, too – stainless steel fittings crafted for special use are also available.

Three way solenoid valves have long-life operation

solenoid valve is an isolated type with an Elastomeric membrane that hermetically isolates the solenoid actuator from the fluid, making it less sensitive to abrasive or contaminated fluids thus providing a safe, and long-life operation. The unique pivoted armature switching mechanism does not require a minimum operating pressure and is unaffected by its mounting position. The solenoids coil is continuous duty design and is encapsulated in a compact Epoxy construction that is suited for corrosive environments. The 3-way solenoid valve, Isolating Membrane type is suitable for activating deluge or other water Control Valves using freshwater, corrosive, contaminated fluids or air. 3v solenoid valve is a valve with three ports, usually for mixing or diverting applications. Typically, it is comprised of one inlet and two outlets, but can also be found with one outlet and two inlets in some cases. The inlet port is usually the pressure port, with one outlet normally closed (no flow) and one outlet normally open. 

Wider Application Flexibility of the 4 way solenoid valves

4 way solenoid valves is the simplest method of stepping a multiposition air actuator. Energizing the solenoid steps the valve to its next position, and de-energizing the solenoid resets the mechanical ratchet in the actuator. This implementation, not recommended for two position actuators, can be useful when only a limited number of external events is available on the data system. CE-approved versions are also available.

The direct acting solenoid valves Solenoid Coils and Connectors Provide Quick, Clean Connections:

Coils are Class F rated for 100% duty cycle applications at 122-degrees F (50-degrees C). AC or DC coils can be interchanged on the same solenoid stem. Each Solenoid connector acts as its own junction box, with molded connectors and gaskets to protect electrical connections. Design meets NEMA-4 classifications.

JELPC solenoid valves industrial applications

We offer solenoid valves that feature two or more ports to help more industrial applications accomplish more tasks. For example, 2-way valves feature one inlet and one outlet port and a single orifice, while 3-way valves feature three port connections and two valve orifices. At Solenoid Solutions, our extensive product line includes miniature, subminiature, high-capacity and low-wattage solenoid valves.

JELPC Air and Water 3-Way Solenoid Valves

Available either AC or DC operated with Brass or Stainless Steel bodies for a wide variety of high flow applications.

JELPC stainless steel round body cylinders

The pneumatic air cylinders are an ideal choice for a host of applications in a broad range of industries. Dimensionally interchangeable with leading cylinder manufacturers, the stainless steel pneumatic cylinders is perfect for replacement applications as well as new designs. There's no maintenance required with these non-repairable cylinders, just millions of trouble-free cycles. 

Steam solenoid valve fault detection techniques

Steam solenoid valves after withstand electrical control signal can take the initiative to open or close the valve, to achieve off pipe steam or flow conditioning control, and thus the system in the steam temperature, flow, pressure and other parameters automatically adjust or long-distance control solenoid valve. Because the steam solenoid valve to use textiles, printing, plastics, chemical, pharmaceutical, rubber, building materials, machinery, electrical appliances, food, such as automatic control system, the use of extremely broad. Following small for us to introduce, steam solenoid valve problems arise after the investigation tips.
1, if the lugs loose or thread off, electric solenoid valve shall be fastened thread.
2, coil burn, remove the solenoid valve wiring, measured with a multimeter, if open, the solenoid valve coil burned out.
3, steam solenoid valve stuck. Cooperation gap solenoid valve slide valve sleeve and spool with a small (less than 0.008mm), are usually one-piece installation, when a mechanical impurities into or too little lubricant, it is easy to get stuck.
4, the lack of air pressure leakage will form, making forced opening and closing valve is difficult, because the gasket is damaged or slide valve wear and the formation of several cavity channeling gas.

It turns out that foot pumps

It turns out that foot pumps, like the vast majority of hand pumps, have a flap, either plastic or aluminum, whose function is to block the entrance of the air once the inflation nozzle has been inserted into the valve of the chamber . Up to that point everything is correct and easy. But as is normal, these pumps and other pumps are designed for standard size wheels, either road 700cc (28 "or" 29 ") or mtb 600cc (26") or even folding or bmx 20 "( Ertro 406) In all of them the radius crossing, or the angulation of these if not crossed, allows to perfectly unfold the locking flap, because there is enough distance to the hub. 3/8 (Ertro 349) can not be done easily, since if you manage to enter it, then it costs a lot to remove it without forcing it out because of the small size of wheel and short distance between the intersection of the spokes and the hub.

Cryogenic solenoid valve troubleshooting

There is a rather special class in many types of electromagnetic valve solenoid valves, the solenoid valve is low. Ultra-low temperature solenoid valve with a long life a bit, and its simple structure, easy maintenance, the use of special valve made of stainless steel, has a good wear resistance and low temperature resistance, widely used in the nuclear industry, military, petrochemical, shipbuilding, aerospace industrial automation control and other fields. So in daily use, among other factors due to improper operation will encounter this kind of problem.
1, liquid cryogenic solenoid valve prone to failure problems are mainly consumable parts and seals and other coil, the coil burned out due to work overload caused the seal itself is wearing parts, mostly as a result of the prolonged natural abrasion.
2, cryogenic solenoid valve at work, if the vibration occurs frequently, it is very likely to cause damage to the valve member, and therefore low temperature solenoid valve maintenance, should guarantee the stability of the work environment, regular solenoid valve components fixed, such as nuts and bolts and the like.
3, regularly clean up the demolition cryogenic solenoid valve internal impurities, and check whether the various parts of the hydraulic solenoid valve has serious wear and tear, and to consider the replacement or repair damaged parts according to the actual situation.
4, at low temperature solenoid valve disassembly time, to conduct power and other ancillary closing the connection, and pay attention to the order of installation in various parts of the solenoid valve during the disassembly.
5, under the conditions allowed, if the solenoid valve in the workplace is important, be equipped with a dedicated maintenance personnel, to ensure the stability of the work of the solenoid valve and low failure rate. In order to make it work more efficiently, lower maintenance costs, longer life.

Jelpc solenoid coil​ working principles

Jelpc solenoid coil principle: The use of magnetic field around the existence of the wire through the established, to spiral it around to strengthen the magnetic field, that is, with the smallest space to achieve the highest magnetic field strength, coated with a layer of insulating paint on the wire instead of the ordinary wire is also for save space.
