Radiator valves are necessary plumbing devices to have if you maintain a boiler or a heating unit. Picking the right type of radiator valves can ensure efficient control of the room temperature in an office or warehouse setting. Radiator valves also work as important components for managing steam and hot water in industrial equipment or facilities.

The most common type of radiator valve is the thermostatic radiator valve, which is installed with most pipes in plumbing to control hot and cold water temperatures for water output. Steam radiator valves and parts such as radiator thermostats are appropriate for boiler room or steam heating equipment. Radiator thermostats may be installed vertically or horizontally, depending on the model, to properly monitor air temperature in a room. Automatic radiator valves don't require a lot of manual adjustments, and they save energy by keeping air out of radiators. Automatic radiator valves also reduce noise and pipe corrosion. Once you've become acquainted with radiator valves basics:

1. Pick steam radiator valves, thermostatic radiator valves and other radiator valves from certified manufacturers.

2. Choose from different varieties, including stainless steel radiator valves, brass radiator valves or automatic.

3. Consider services for radiator valve repair in case equipment malfunction occurs.

These radiator thermostats control the temperature settings for radiators by regulating the flow of water. Styles include straight, angle and side mount. Operators attach with/without remote sensors. These items aren't compatible with separate electronic thermostats.

I recommend: Buy online an automatic radiator valve actuator controller in several models and types at All Thermal Controls. Select the brand name you need, including Danfoss, Honeywell, Macon and Taco, to proceed to types and prices for online ordering at Garnet Midwest; radiator thermostats are also available.

Work with a radiator valve manufacturer for products or solutions

Contact manufacturers that make products for commercial, OEM and residential plumbing and heating markets.

I recommend: Contact Hydronic Alternatives, an OEM for a variety of radiator accessories. View product line, part number and description by clicking “Products-Radiator Accessories-Valves” for selections that include radiator thermostats, single entry bottom feeds and reverse angle pattern valves among others. Contact Watts Water Technologies for supply valves, thermostatic and bronze or brass steam radiator valves.

Locate suppliers and distributors with in-stock radiator valves

Find coin key air valves, auto vent, brass and bronze valves and valve nuts and tailpieces. You can even find antique radiator valves for rehab projects.

I recommend: Contact Matco-Norca, or click “Valves & Specialties,” then “Radiator/Heating Valves” for brief descriptions of radiator steam air and supply valves. Check out the selection of valves and order online at MSC Industrial Direct. See photos and descriptions of current antique radiator valves in-stock at A-1 New and Used Plumbing/Heating Supply; then call or email from the information given at the bottom of the page.

• •  Instead of a radiator valve repair, especially in older buildings, warehouses and garages, consider installing a thermostatic radiator valve. These valves replace the on-off valve on each radiator in two pipe systems and for one-pipe steam systems, the valve replaces the air vent. The results include lower heating bills in a single unit or building complex. Monitor with wire or wireless sensors that control off and on for heat.

Proper radiator valves education and training can help keep your utility bills lower and reduce repair and maintenance bills by keeping your home or business in proper working condition. Whether it's learning to read radiator thermostats, adjust steam radiator valves, change antique radiator valves or repair radiator valves, having the proper know-how can help save you time and money in the long run. It must be cautioned, though, that if you are at any point uncertain as to what you are doing, please seek the help of a paid professional to do the job for you.

Radiator valves education and training can come in the form of online videos, instruction directions and/or diagrams. You can use these tips to install, upgrade or repair your existing radiator system.

• •  When using online videos as your radiator valves education and training, don't hesitate to pause the video or wind it back as needed. The moderator of the video is a trained professional who can probably work with a radiator valve in his or her sleep. You, on the other hand, cannot rush quality. So take as much time as you need, and stop the video as often as you need to.

Radiator valves control the temperature to heating units within a home or building. These valves must be operating properly in order to properly heat a building and reflect an accurate temperature on radiator thermostats.

Thermostatic radiator valves read the room temperature and help maintain preset temperatures on radiator thermostats. These radiators valves are more expensive than standard radiator valves, which simply control the temperature on the radiator. When setting up a new system or preparing for a radiator valve replacement, consider the following radiator valves pricing and costs information before ordering from a radiator valve manufacturer:

1. Thermostatic radiator valves have sensors that read room temperatures and are typically more expensive than standard radiator valves.

2. Brass radiator valves can be an inexpensive replacement on an existing radiator.

3. Steam radiator valves can often be used for hot water or steam radiators.

Action Steps
