6 WAY ZONE VALVE

The most compact six-way zone valve in the HVAC industry with QM (Quick Mounting) assembly between the valve and the actuator, and directly connect to the flexible hoses. The six-way zone valve allows you to manage the supply to a single user from two different sources of thermal energy, or to easily manage 4-pipe systems (typically used in heating and cooling applications). A single actuated valve can substitute two or more actuated valves, easily resolving any complications with synchronization for the opening/closings of the two sources. The six-way zone valve allows the system change-over from heating to cooling within the quarter turn and also the simultaneous closing of the supply from both sources at 45°.

These valves are typically used in radiant ceiling systems, in particular for the service sector, where the change-over from heating to cooling can be easily managed, even when this is required during the same day, and can be carried out independently for each zone.

Automated Flow Balancing Valve

The Automatic Flow balancing Valve uses the latest flow technology to assure that the designed flow rate is achieved at all the times, in the whole system, irrespective of any pressure changes within the system. The solution ensures the desired flow rate for your cooling or heating water distribution system. In brass with 1/2″ sweat end connections, available with 0.5 GPM increments up to 6 GPM.

Dampers make up a critical part of HVAC systems and getting the selection right is vital to long term performance. Here’s what you need to know to choose the right damper.

The basics

Dampers are used to control airflow through certain portions of an HVAC system. You may need them to open and close or you may need them to modulate for variable airflow. They may be duct-mounted, wall-mounted or integrated into air handling equipment. Specialized dampers like smoke dampers limit the spread of smoke through ductwork and air transfer openings.

Dampers are constructed from metal (aluminum or steel) and consist of a frame and moving blades. The position of these blades determines how much air can flow through. Dampers may be have parallel or opposed blade arrangements. Parallel blade dampers are better suited to open/close applications while opposed blade dampers work well for modulating airflow.

Sizing and selecting a damper

Sizing a damper begins with the maximum airflow through the damper using the equation:

Airflow = Velocity x Cross-sectional area.

For dampers, the cross sectional area is the free area, which is the area available for air to flow when the damper is fully opened. Manufacturers publish this information in charts. Once you calculate your free area for a given velocity, use these charts to find the height and width for your damper.

To ensure that the dampers don’t create airflow problems in your system, the fan must be able to overcome the damper pressure drop. Depending on the situation, you may have to oversize your damper to reduce the pressure drop.

Choosing a velocity to size the damper depends on the application. The velocity for intake should be limited to 450-500 feet per minute (fpm) to prevent rain from entering. Exhaust velocities can go up to 1200 fpm.

Another decision you have to make when selecting a damper is whether the blades need to be weather-sealed or insulated. Weather sealed and insulated dampers are suitable for intake and exhaust dampers that are open to the exterior.

Controls

Dampers can be manual or automatic and with the increase in building automation, getting control right is important. This is where actuators come in. Our next article will discuss actuators in more detail.

What Does an Electric Actuated Ball Valve Do?

Before you start your quest to find the ideal electric actuated ball valve, you should know just what they do. These valves serve an array of industrial and commercial applications. In HVAC, they direct air flow in certain manufacturing operations. Even when they’re used to move water, electric actuated ball valves are technically listed as an HVAC component. The most common use in this regard is in industrial water chillers, which help cool any equipment that’s at risk of overheating.

In addition, electric actuated ball valves are ideal for situations that lack a compressed air supply, as well as applications where a solenoid valve is incompatible.

Electric Actuated Ball Valves Versus Other Ball Valves

When you’re trying to control air flow, you have an endless amount of options. Pneumatic, manual, hydraulic, and spring ball valves are all easy to find and work for most projects. The advantage of employing electric actuated ball valves is that they’re easily wired in parallel electric circuits, providing a plethora of benefits that keep your system running smoothly as long as power continuously runs to the valves. Other valves rely on other types of sources to work, and most often, they aren’t nearly as easy to control or access.

What are the Advantages of Electric Actuated Ball Valves?

In short, the advantages of electric actuated ball valves lie in their versatility. For example, these ball valves come in a variety of materials to suit the task at hand. Stainless steel, brass, and PVC (polyvinyl chloride) are three of the most popular materials for the valves, offering different price ranges and benefits. For example, stainless steel is more malleable than other substances, while PVC is an inexpensive alternative.

Electric actuated ball valves also come in two-way and three-way varieties. This helps streamline the automation process for your needs. Two-way varieties can accurately turn air flow on and off at the touch of a button, or as part of an automated unit. Three-way valves allow you to close air flow or change air flow in rapid succession for maximum efficiency.

When you need electric actuated ball valves for your business, you don’t want to take chances on units that lack quality or durability. That’s what makes Enolgas USA a solid choice. Since 2008, Enolgas USA has produced only the highest quality actuators and valves in the world. Don’t hesitate to contact them for your next purchase. It might be the best choice you make.

What Are Valve Actuators?

To understand what an electric actuated valve is, you first need to understand the nature of valve actuators. A valve actuator is any device that employs a source of power to open or close a valve.

Often, that source of power is a human being. As in, a person must be present at the valve site to apply rotational force in order to open or close the valve. As you can imagine, this is often inconvenient and can cost precious time. For example, if there is an emergency within a plumbing system you may have to wait hours until a plumber can shut off the valve if you’re not familiar with how to do it.

Other valves are automatic. They may be operated by a variety of means, including electricity, hydraulics, air, or springs.

Advantages of Electric Actuated

The biggest advantage of electric actuated valves is they can be remotely operated. Therefore, if there is a plumbing emergency the valves can easily be shut off before a bad situation gets any worse.

Electric actuated valves are also energy efficient. Not only can they prevent excess water flow, thereby saving you money on your water bill, but the valves themselves do not consume a great deal of energy. According to Flow Control Network, which focuses on designing, maintaining, and operating fluid control systems, “It is often said that control valves wastefully expend energy, but this is not true. Modern control valve design and sizing methods allow for the use of pumps with smaller head pressures, resulting in less energy absorption via the pressure drop across a control valve.”

Electric actuated valves are often used in industrial settings, but they can be useful in any fluid management system.

Electric Actuated Valves as Part of a Water Security System

A water security system can prevent flooding, prevent water damage, and reduce water waste. Electric actuated valves can be an integral part of such a system. The valves may have sensors that detect when water flow is too high and automatically shut off. This monitoring capability does not consume a lot of energy and can be especially valuable when you are away from home for extended periods of time and aren’t around to notice if something is off with your water system.

You don’t have to be an expert to understand that electric actuated valves can benefit you and your home.
