Buy Double Solenoid Valve
Direct-Acting Solenoid Valves open and close regardless of the pressure and flow: so long as the published maximum inlet and back pressure are not exceeded. In Direct-Acting Solenoid Valves the energized coil magnetically pulls-up on the core, which is attached to the shaft and seat, thus overpowering the spring and opening the valve orifice. For closing, the coil is de-energized and the spring now pushes the core, shaft and seat back to the normally closed position. This style valve does not require any minimum line pressures or differentials to operate. Examples of Direct-Acting Solenoid Valves include Plast-O-Matic Series EASYMT/EASMT, EAST, EASYM, EASM, EASTMD/EASMD and EUC Models. A well known Company for Steel solenoid valve is Gould, J. D.

Ball valves is a general term we use for a distinct category of valves, which includes fire safe ball valves, panel mounted ball valves, actuated ball valves, high pressure ball valves and the likes. A ball valve, often referred to as a quarter turn valve, opens by turning a handle attached to a ball inside the valve. The ball includes a port or a hole that blocks flow through the valve. Once the port is in line with the ends of the valve, flow will be released. The materials from which ball valves are manufactured are metals, ceramics or plastics (or a combination of the three). To make the ball inside the valve more durable (remember, it will be the subject of high pressures and flow stress), some Alco ball valves are chrome plated to increase toughness. The liquid passageway is constructed so that if it’s not in line with the ends of the valve, no spills occur; protecting the valve and the system you are using it for. Ball valves are of various types like two way, three way, four way, and five way.
A solenoid valve is a device that controls the flow of liquid or gas, and there are several types. Direct-acting solenoid valves block or release liquid and gas flow, but the actual pressure exerted on the valve by the liquid or gas does not determine when this happens. Consequently, there is no minimum pressure required to cause the valve to operate. The exception to this is when the pressure exceeds a predetermined maximum. Direct-acting solenoid valves are controlled by a power source that is applied directly to the device, energizing a coil. When energized, the coil creates a magnetic field, causing a core to push down on a shaft attached to a seat, thereby opening the valve. The magnetic field is strong enough to counteract the force of a spring, and in the absence of this energy, the spring once again moves the component parts back into their resting positions, closing the valve. A number of models from the Plast-O-Matic series are direct-acting solenoid valves, examples of which include the EAST, EASMT/EASYMT, and EASYM models. Other examples are the EUC, EASM, and EASTMD/EASMD Models. One of the principal companies that sell steel solenoid valves is J.D. Gould Company, Inc., which is based in Indianapolis, IN. In addition to manufacturing valves, it is also a service company.

Ball valve is an umbrella term that denotes a distinct class of valves. This category includes fire-safe ball valves, panel-mounted ball valves, actuated ball valves, high-pressure ball valves, and many others. Ball valves, which are often referred to as "quarter-turn valves," open by means of a turning handle that is attached to a ball inside the valve. The ball works in conjunction with a port or a hole. When moved up against the port, the flow of gas or liquid through the valve is blocked. When the port is in line with the ends of the valve, the flow is restored. Ball valves are manufactured with various materials, including metals, ceramics, or plastics. Various combinations of these materials are also possible. The ball inside the valve sometimes needs to be endure a lot of pressure. In these cases, they can be given a coat of chrome plating to make them more resilient. This is true of Alco ball valves. The passage trough which the liquid passes is made in such a way that if it is not in line with the ends of the valve, no spills occur. This ensures that no damage is done to either the valve itself or the system of which it is a component. Ball valves are of a number of types, including 2-way, 3-way, 4-way, and 5-way valves.
