Asco Control Group: Motorized Valves
ASCO valves are definitely some of the company’s most famous and acclaimed products, not only because of their high-quality and extremely reliable, but also because their tradition in manufacturing valves, the company actually being the first to manufacture a solenoid based valve system, back in 1910. The company came out to be one of the leading manufacturers in the HVAC industry and specialists and contractors all over the world received a huge helping hand with the new manufactured motorized valves. The fuel, gas or oil motorized valves handle combustion system needs and are very popular in industrial, commercial or home applications.
The electro-hydraulic motor operated valves are available in different versions, ranging from 2-way normally closed valves, 3-way diversion valves or manual reset valves. Some distinctive features that these motorized valves posses include visual indication, pipe taps, closure proofing and strong bronze, aluminum or cast iron body structures.
The HVAC PLUS product catalog includes many motorized valve categories, the difference between them being either the use of another type of actuator, the number of inputs and outputs of the valve and the structural metal or alloy used in the valve’s cast. The series are as follows:
· 2-way, Normally Closed, Aluminum Body Gas Valves (V710 Series)
· 2-way, Normally Closed, Hydramotor Actuator, Cast Iron Body Gas Valve (H-Series)
· 2-way, Normally Closed, Hydramotor Actuator, Bronze Body Oil Valve (HOV-1 Series)
· 3-way, Normally Closed, Hydramotor Actuator, Bronze Body Oil Valve (HOV-13 Series)
Most motorized valves coming from their use AH series, Hydramotor actuators. The AH series model is a push-type, self-contained electro hydraulic linear actuator, that gives out the best results when a motorized valve is combined with them. The provide excellent control of main gas lines, commercial burners, industrial burners, home heating and other HVAC systems that it can operate in. The AH series includes on/off control, manual resets, modulating and low or high control of the handled fluid or gas.
The 2-way, Normally Closed, Aluminum Body Gas Valves hold V710 motorized valve models, that have a push-to-open type body, with on and off or proportional control. The V710 are mounted on a Hydramotor actuator AH and it can be purchased in 4 trim styles: quick opening with valve seal overtravel, standard quick opening, standard linear and linear with valve seal overtravel.
The 2-way, Normally Closed, Hydramotor Actuator, Cast Iron Body Gas Valve series consists of models H117, H118 and H137. These fuel gas shut-off valves are usually employed in industrial settings, appliances and environments, processing heating operations. The most common usage of this type of valve is in industrial boilers, the cast iron body and the closed Hydramotor actuator-based system being perfect for larger heating appliances such as boilers. Each model offers a different pressure and flow rapport: the H117 has low pressure but high flow, the H118 has high pressure and low flow and the H137 has both high pressure and high flow. A great and useful (not to mention safe) feature of these valves is that they close almost instantly, in about a second tops, when they are shut off or when power is removed (or a power failure occurs, case in which this feature will prove vital to keeping your operations safe).
The ASCO 2-way, Normally Closed, Hydramotor Actuator, Bronze Body Oil Valves consist of globe type models which are seated with Teflon, making them ideal for larger oil fired industrial heating applications. Of course, commercial technicians and engineers can also use these valves on their system, but their more common role is in large industrial operations. These valves’ pipe connections range from 1/2” to 1” and just like the H-Series, they have a quick turnaround time when it comes to shutting off. Again, in a large industrial oil-based heating appliance, a quick valve closing time when power is either removed or failing, could prove not only useful, but also vital. called HOV1.
The last ASCO motorized valve series, the 3-way, Normally Closed, Hydramotor Actuator, Bronze Body Oil Valves, include the HOV13 models. These models are similar to the HOV1 models, in that they are globe type and Teflon seated. They offer 300 psi fuel oil shut-off and diversion valves and are also most commonly used in large industrial environments. The major difference between the HOV1 and the HOV13 is that the latter is a 3-way motorized valve, meaning that the normally closed output offers shut-off, while normally open ports permit diversion of flow from the burner to the system. Pipe connections are also somewhat smaller, ranging from 3/4” to 1/2”.
Mostly used in industrial applications (although some commercial operations also found them useful), the motorized valves are extremely safe and reliable, offering 100% control on the heating system of your application.
