If you need support to design custom solutions and to create special products, at MSD, we work with you to study your needs, analyses your applications and design the best solutions. Our technical department is available to cooperate in design special solutions. We hope to work with you to develop the best ideas and advance proposals that are always innovative and competitive. MSD products have a robust design and are manufactured with utmost precision to ensure safe and reliable functioning.
Solenoid valves are electromechanical valves used to control the flow of liquids or gases. Because of the advantages in the way of safe and rapid switching, reliability, long service life, and compact design, solenoid valves are very popular in a variety of industries.
Our solenoid valves range includes 2/2, 3/2, 5/2, 5/3 Direct and Pilot action, Normally Open Normally Close, Universal, Manual operated, Explosion Proof, Intrinsically safe and Low Power SOVs. This range offers services such as: releasing, mixing, shutting off, dosing or distributing fluid or gas.
Some common applications include Automatic valve actuators such as Shut Off Valve, Line Break valves, ESD valves, refrigeration, HVAC and air conditioning, power washing, agricultural air conditioning, pneumatic and hydraulic systems (motors, cylinders, buffers, etc.), compressed air systems, automotive engineering and household appliance.
MSD produces solenoid valves via a variety of processes, such as: CNC machining, laser welding, injection molding and coil winding. Once the valve components are fabricated, they will be assembled. These components include: the solenoid valve coil, the valve, an inlet port, an outlet port, a spring, an orifice and an actuator. Often, solenoid also feature seals.
MSD have a wide variety of materials available with which to construct our solenoid valves ranging from both plastic and metal materials, such as PVC, natural polypropylene, PTFE, CPVC, stainless steel, bronze, aluminum, and brass. Seals, like Viton seals or NBR seals, are usually made from some sort of rubber. In addition, we will make stainless steel seals.
Solenoid valve is made based on application specifications such as: nature of fluid/gas inside pipe (corrosiveness, hazardousness, viscosity, acidity, etc.), environment, frequency with which the pipe will be used and application standard requirements. Based on the specifications, we can choose design aspects like: valve size, valve material, valve type and configuration and number of ports.
We are able to customize your solenoid valve system in a number of ways. For instance, we normally create valves with two connection areas and one orifice, but we can also make you valves with three connection areas and two orifices. Likewise, while we usually design valves to run using a low power source. We may also provide you with specialized: pressure levels, spring return, valve size, etc. Also in the plants such as pharmaceutical plants in which hygiene and efficiency play a key role in the processes, MSD offers cost effective and reliable solutions. Chemical and petrochemical plants have a corrosive and aggressive environment. Such plants need products that are not only reliable but also capable to withstand such abuse. The range of material
Solenoid valves function using two main components: a solenoid coil and a valve. The coil is a magnetized wire coil that comes alive from a series of electrical charges and then emits a current flow. This current flow generates a magnetic field that converts electrical energy into mechanical to move the actuator. The actuator is an extension of the valve; it, along with an attached string, is responsible for moving the valve from an opened to closed position.
Solenoid valves are generally built as either normally closed (NC) or normally open (NO) devices. Normally closed valves operate with an inner plunging rod or pin, called a plunger, held in place by the solenoid coil, that blocks current flow. To activate flow in an NC valve, an electromagnetic charge must be sent through the coil, which will then lift the plunger out of the way to allow flow. NO valves, on the other hand, are the opposite. They will close when the solenoid is activated.
Solenoid valves are classified based on many different features and components, to help manufacturers select which valve may be best, some of them are as following:
- Valve construction/design,
- Power supply,
- pilot-operated or direct-acting
A pilot-operated solenoid valve, uses a diaphragm rather than a plunger to create differential pressure and thereby control flow.
A direct-acting solenoid valve uses a plunger that has direct contact with the in-flow valve body opening, called an orifice. In this case, the plunger opens and closes the orifice to control flow.
High-pressure solenoid valves are excellent resources for flow control in areas that are incompatible with other valves, like in work areas that engage with dangerous machinery or inaccessible lines.
Stainless steel solenoid valves, as their name indicates, have a stainless steel body. Because stainless steel is corrosion and abrasion resistant, stainless steel solenoid valves work well with chemical processing applications, which require outstanding control of bases, acids, and analytical reagents.
Miniature solenoid valves are the perfect size for delicate medical equipment like biotechnology equipment, portable medical devices, and gas analyzers.
A poppet valve, sometimes called a mushroom valve, consists of an oval or round hole, along with a disc-shaped tapered plug located at the end of a shaft called a valve stem. The poppet valve, which can be closed or open type, is used for controlling engine air/gas flow quantity and timing. It is made from stainless steel or brass.
Solenoid valves made from brass are great for use with non-corrosive substances, like inert gas, water or light oil. They are not strong enough to carry highly corrosive substances.
Solenoid valves made from PTFE, also recognized by its brand name Teflon, are a great choice for harsh gases and corrosive fluids.
With fewer moving parts than other valves, solenoid valves are comparably low-maintenance. They are also operable by remote devices, which is an invaluable feature for hazardous applications. In addition, they can be made portable. Finally, solenoid valves are flexible; able to use either hydraulic or pneumatic power.
Typical solenoid valve accessories include: connectors, manifolds, screws, gaskets and lights. Of these, connectors are most common. They help you put together more complex valve assemblies. To find out what accessories are best for your application, talk to your manufacturer.
The standards to which your solenoid valves will need to adhere depend on your application, industry and location. For example, if the valves will be coming in contact with drinking water, the solenoid valves must be lead-free. We ensure customers our valves are able to meet all of their specifications, including certifications, lead times and budget. Don’t forget to talk to us about that. In addition, we will be available for installation assistance, onsite training and availability for consultation, parts maintenance and parts replacement after installation.
