How does a zone valve on a Honeywell v8043 work?
A Honeywell V8043 zone valve has a rubber BALL that rotates on an axle at the end of a shaft. Every time the valve opens and closes, that rubber ball rotates slightly so there’s always a different circular area on the rubber ball contacting the brass seat to shut off the water flow.
Is it possible to wear out a Honeywell zone valve?
The internal guts of a Honeywell V8043 series zone valve is similar in that regard to the seats on Crane Dial-ese faucets; it’s almost unheard of for them to wear out.
Is the Honeywell 8043 power return valve closed?
The Honeywell 8043 is Normally Closed. When it is powered up, it opens. When the power goes off a spring return closes this valve. I have read the specifications sheet for this valve along with other specification sheets.
Can a zone valve be replaced without draining the heating system?
1. If that zone valve was built within the past 30 years, you should be able to replace the power head on it without draining the heating system. 2. MOST of the time, any problems with the operation of your Honeywell zone valve will just be due to internal friction in the motor.

Which is the best Honeywell zone valve model?
Honeywell V8043F series are the most popular zone valve models with terminal block (hardwired) electrical connections, end switches and sweat connections.
What kind of valve does a v8043b have?
The V8043B series valves are a normally-open version of the V8043A series without a manual opener, but with similar characteristics and specifications. These zone valves are 2-way valves with an auxiliary end switch, 18″ leads and a manual opener, available in 1/2″, 3/4″ and 1″ sweat connections.
What causes a Honeywell zone valve to get stuck?
MOST of the time, any problems with the operation of your Honeywell zone valve will just be due to internal friction in the motor. What happens is that friction causes the motor to get stuck in one position, and the thermostat applying voltage (or interrupting voltage) to the zone valve is not enough to get that motor turning again.
