Product Q&A
10 QuestionsQ: Is the contact between the flapper and body metal on metal? Or is it metal against some kind of seal (e.g. rubber) material?
Asked by MarkL 9 years ago
Add your answer
It's machined metal on metal. It will seal just fine. I use them in hydronic heat applications where rubber would not be advisable. This is an excellent check valve when installed correctly in a horizontal position. Jay Clark Managing Partner Critical Infrastructure Mapping LLC Geospatial Services
Q: can this check valve be mounted virtical or horazonal and work ?
Asked by earle the fixer. 11 years ago

Only horizontal. For vertical you need a spring loaded valve. Jay Clark Managing Partner Critical Infrastructure Mapping LLC - Geospatial Services
Q: Can this be used in the condensate return is a low pressure steam system?
Asked by Jr plumber 12 years ago
Add your answer
Verified Reply- PexSupply StaffThe temperature rating on this check valve is 180 degrees Fahrenheit so it would not work in a steam application
Q: Can I use this 1 1/4 threaded swing check valve by Hydrovalve on a ram pump project as demnostrated in youtube.com
Asked by Rolando 12 years ago
Add your answer
If the operating pressure of the hydraulic ram does not exceed the pressure of the check valve then yes, it will work. If the hydraulic pressure in the ram exceeds the operating pressure of the valve it will not work. To answer the question the user needs to understand the pressures involved.

Q: can this valve be installed in a city water line to prevent backflow and will I get excessive pressure drop through valve?
Asked by Bill 12 years ago
Add your answer
No excessive pressure drop. It will prevent back flow, but most inspectors will not accept on a domestic water supply.
The item is made of Bronze and hence environmentally safe. Yes you can use in the city Waterline. And Yes, there is very negligible pressure drop. The valve will close when the flow is reversed( due to reverse differentials). Hope This answer your concerns. http://wwwapps.ups.com/WebTracking/trackhttp://wwwapps.ups.com/WebTracking/t rack
No, you will not notice any pressure drop or change whatsoever. The valve is used to precent backflow, if it does not, then the valve is not operating correctly. drVinnie
Q: Can this valve be disabled to temporally allow flow in both directions?
Asked by Andy 12 years ago
Add your answer
The valve diaphragm( made of Bronze) inside the valve floats vertically due to gravity. The valve opens in the direction indicated due to forward water pressure . But it shuts closes in the opposite direction to prevent back flow. Hence the water cannot flow in both direction. You may need a solenoid operated valve to meet your needs to disable for your application.

Q: What is the temperature limit?
Asked by Clay 13 years ago

Verified Reply- PexSupply StaffThe valves are rated up to 180°F.
Q: I have a well and pressure tank. The pump appears to come on regularly although no water is being used. The tank is maintained at about 40-45 psi. The pump should only come on if the pressure goes below 40 psi. There does not appear to be a check valve in the system. If there is one someplace that I have not seen, it appears to not be working (maybe there is one at the pump). I am considering using this valve so that the pump does not cycle when it does not need to. Will this valve work this?
Asked by ET 14 years ago
Add your answer
Verified Reply- PexSupply StaffYes, this valve should work for you.
You most likely have a fautly foot valve. If your pump is a submersible(in the well), the "foot" valve should be located in the well at the connection between the pump and the tubing. If your pump is located external to the well, then there is normally a foot valve at the bottom of your "in-well" tubing, at the inlet strainer. You can install a check valve at the water tank to prevent losss of pressure, but there is the risk that your pump may loose it's prime during periods of no water usage.
Q: Can this valve be installed in a vertical position so that there is a more positive stop to the check valve?
Asked by Karl 15 years ago
Add your answer
Verified Reply- PexSupply StaffNo, it cannot be installed in a vertical position, as per the manufacturer.
You could make a short section of horizontal pipe and mount it there. Then continue your pipe in the former direction.
Q: can this valve be installed in a vertical position so the flap has a more poitive closed position due to gravity? The amount of force o open it seems like i would still be vey little. Thanks
