How do automag zone valves work?

The long lasting Automag Zone Valves are powered closed, therefore if power fails, our valve will automatically open. We provide flow with low pressure drop and overall lower power consumption. There are no gears to strip, or wax conductors to break down. Available in 3/4 inches or 1 inch, two port configuration.

What happens when a zone valve fails?

If power to the valve fails, it can be opened manually, allowing some circulation by gravity (Figure 4). The valve automatically returns to normal operation when power is restored. The manual-open position is recommended during soldering to keep from overheating the ball plug.

What is the purpose of a zone valve?

A zone valve is a specific type of valve used to control the flow of water or steam in a hydronic heating or cooling system. In the interest of improving efficiency and occupant comfort, such systems are commonly divided up into multiple zones.

Can a zone valve get stuck open?

If the motor to the power head has gone bad, the valve can be stuck in an open position. Using a small hammer tap the valve lightly. If the cover closes then that confirms that you have a bad power head. If the valve stays open you may want to continue to troubleshoot for blockages or damage to the valve head.

How do you know if a zone valve is bad?

To test if your zone valve is working, switch off demand for your hot water (you can do this via the timer – set Hot Water to Off). Now create demand for central heating – turn up the thermostat and make sure the timer is set to ‘On’ or ‘Continious’.

Does a zone valve go on flow or return?

Water Systems New Member If you can get away with it put them on the return as the water temperature is lower. The reason they put them on the flow is that you are virtually guaranteed no gravity flow around the system – it can always be a problem no matter where the valves are.

How do I know if my zone valve is working?

What do you need to know about zone valve controls?

We’ve enhanced our complete line of Zone Valve Controls with the features and styling you’ve been asking for. Whether you’re looking for switching relays, zone valve controls, priority zoning circulators, or fan controls, Taco has everything you need.

What are the actuators for Siemens zone valves?

Siemens Zone valves are available in ½- to 1-inch line sizes with Cv ranging from 1.0 to 7.0. These valves can control hot and chilled water, with up to 50% glycol, over a temperature range of 35° F to 230° F. On/off fail-safe and floating or modulating fail-in-place actuators are available.

Where can I buy Taco zone valve controls?

Support is only a click away! Our dedicated customer service and tech support teams are waiting to hear from you.

How does a magnetic latching valve shift from one state?

To shift the valve from one state to another, a short 50 millisecond DC voltage is applied to the coil. To shift the valve back, a reverse polarity pulse is applied to the coil. This feature makes this valve suitable for use in remote areas where continuous power may be limited.
