3/4" Horizontal Angle Valve Body for High Capacity Radiator

The Honeywell V110 series valves have only 3 threads to hold the valve body to its radiator bushing. It needs 5 threads avoid side pressure on the supply pipe and to seal the water pressure to avoid leaks, especially if the system uses low-pressure steam. Honeywell has a newer thermostat valve and actuator that is less expensive and has 5 threads. Checkout the V2040ASL20 valve and the T2001 actuator, also sold by SupplyHouse. The valve body appears to be a zinc casting. The bushing is brass. The radiator is cast iron. Ergo, it needs an insulating fitting to avoid galvanic corrosion. Teflon plumbing tape may work to avoid this problem and help seal the threaded connections. Please be very cautious. It is easy to cross-thread and ruin the valve body with soft metal and only 3 threads. Also secure the supply pipe when you take the old valve off to make sure the pipe does not unscrew on the wrong end. I hate to see grown people cry.

I have previously purchased this item, my review is the same. Please refer to my eariler comments..

This item functions as advertised !! But, I do have a negative comments... 1.This valve installation could have been and should have been very easy to be installed. The terminal threading and end dimensions both match existing conditions. HAD the internal seal of the new union matched the internal seal of the existing union, the installer would have the option to use the existing union outlet nipple or use the new union outlet nipple..(Radiator inlet connection) The existing nipple can at times be very difficult to remove from the radiator, but still be in good condition and could be reused. However, the new union internal seal does not match, thus not permitting a tight seal if using the existing union outlet nipple.

I have a 100 year old townhouse with original radiators (radiators probably not as old as the house). I removed the old natural circulation piping and manual thermostats to save energy costs. These radiator valves allow you to set a different termperature in every room without zoning the entire system. Showed up new, solid casting and robust. The valve actuator had a nice rubber cover to protect it during installation. No problems so far.

Does what it is supposed to do.
