Q: I want to use this for a hot tub....so when I send 24volts to it it will open.....when the 24 volts shut off will this valve automatically close without power? and if it fails will it fail in the closed position?
Asked by ron 13 years ago

This will close without power, it is closed when power is not present. Sent from my mobile device
I am using this valve for the same purpose. The valve opens when energized, valve will close when not energized and should fail closed Connected by DROID on Verizon Wireless
This is a diverting valve 2 ports will always be open.
When you turn off the power, it goes back to the original position. It can fail in three ways, one is the motor could fail so it would never open. Two is the spring could break so it never closes. Three is something gets jammed in the valve (calcium, rust, etc.) and it either doesn't open all the way or doesn't close all the way.
This valve is designed to flow the direction of the arrow normally (or as looking at it with the green unit at the top) flows from bottom to the right in the picture. It will stay that way until an applied 24V moves the "plunger" in the valve body to change the flow to straight (left to right in the picture) through.
Q: I use a modulating boiler to heat 3 zones using taco sentry zones and one taco 0011-F4 pump. When one of the thermostats call for heat, the proper zone valve will open, then boiler and the taco pump start together. My concern is that when the thermostat is satisfied the zone valve(s) will close but the pump continues to run for about 30 additional seconds with no place to send the hot water. The pump is switched on and off by the boiler which I assume was designed to run the extra time to flush the heated water out of the boiler but it can't. Is this going to ruin my pump or boiler and do I need to redesign the system somehow? Thank you.
Asked by RMG 14 years ago

Here are my two suggestions: 1) Add a bypass loop in the system that opens a valve that circulates right back to the boiler. This valve could be controlled by a multitude of sensors such as a flow sensor. Or you could add a couple electrical relays to the bypass valve that opens the valve when all other valves are closed and the pump is still running. This is probably the safest option because it was designed this way for a reason. It probably keeps circulating water to give the boiler time to shut down so the water doesn't have an opportunity to boil. 2) A cheaper option would be to cut power to the pump using a relay that's controlled by the thermostats. This wouldn't be my first option.
You should have a time-delay (off-delay) relay to keep the zone valve open for the additional time the motor is on. This will allow the pump to cool the boiler before the zone valve closes.
No.
It takes about 30 seconds for the zone valve to fully close. It shouldn’t be a problem.
Q: is the valve installation water flow direction dependant
Asked by Matt the newbie 14 years ago
Add your answer
Yes, there's arrows cast into the metal sides showing the flow direction. If it's installed backwards, it may not completely shut off the unselected pipe since it uses the pressure to help seal it.
Yes. This valve is designed for a specific flow direction.
Theoretically use but it will work in reverse Stephenne
I guess the short answer is yes. The directional indicators on this valve are a little deciving. In the "Off" position. No power to the valve water will flow in from the bottom of the valve to the outlet port with the arrow poiting out. It would also flow in the opsit direction if you wanted., Once power is sent to the valve the bottom port closes and water would travel in eaither direction through the two top ports. So no it is not direction dependant and yes it is. Depending on how you look at it. I hop this helped. Steve
Q: In the shown upright position, is the bottom port normally closed? When energized, does the bottom port open & one of the other ports close? Thanks
Asked by Fritz 15 years ago

Verified Reply- PexSupply StaffWhen energized, the bottom port closes and the side port opens.
Q: If one port opens when power is applied, does the other port close?

Q: Can I install Taco 3-way Zone Valve in open system? I read that Honeywell zone valve cannot be installed in open system.

Verified Reply- PexSupply StaffWe would recommend the Taco 556-G2 zone valve, which is designed for use in open systems.
Q: Does the 3-way zone valve open when the 24 volts powers the valve? Does the valve go into bypass when the 24 volts is taken away? Or does the valve require a three wire to it?
Asked by Tyler 15 years ago

Verified Reply- PexSupply StaffThis is a 3-wire valve. The valve will open when power is applied to it.

Q: What kind of mounting does this valve offer? Are there bolt holes in the body or is this mounted with U-bolts around the outlets?
