Yes, if you have the parts, and know-how.

If you don't know if it's applicable, how do you expect to re-build it?

"know how" is the possession of the knowledge and skills required to rebuild the valve.

Some valves can be re-built and some cannot.

Although you seem to think that unknown strangers who haven't even been told the specific valve you have (1500 class ball valve hardly defines the valve) can impart the "know how" into you you are sadly wrong.

Contact the valve maker and order a rebuild kit. Be ready to tell them the part number of the valve you have. Then ask them if someone who has no clue about valves will be able to re-build the valve you have.

My advice to you is to order a new valve.

This is hopeless, goodbye.

Parts for valves are designed for that specific application, and are generally certified.

You state 1500# rating, so even if you use parts from a newer model valve, they will not be certified to seal properly on your model. You could be wasting time and money, if the service in which the valve will be used is high pressure/high temperature. The cheapest repair is not necessarily the best repair. I have many years experience doing such work in the oil & gas industry, where the quality and reliability of the repair would be more significant than a cheaper cost.

Typically, we would look at replacement if the repair reached 50-60% of the replacement cost.

Yes, it is very economical to do it. Once trained many pipe fitters, mill wrights, mechanics and other trades can do it. Parts, except for the body, are usually not very expensive, not more than 1/4th cost of a new valve. Make sure you can get the parts before taking it apart. The bigger the valve the more money you are saving by doing it yourself. There are even valve repair shops that do this if you Google for them.

Example-- 2" Apollo 76F-108-27 St Stl threaded full port ball valve with st stl ball costs around $ 147.00. Internal parts that usually go bad are ball (very infrequently), ball seals, stem and packing. Replacement parts approx. $40 max. One hour labor or less and you have a like new valve. 2 piece bodies are the hardest to do because of the torque to separate the two ends. Three piece are the easiest since they are held together by exposed bolts.

The bigger the valve the more $ saved. The more exotic the materials the more $ saved. Since labor is not in proportion to the valve size it is cheaper per valve cost as the valve gets bigger.

Numerous other types of valves such as gate, butterfly, globe, float, diaphragm, needle, check, safety and many other types if valves can be economically repaired. If the body is bad scrap it. Bodies are a large part of the cost of a valve.

Good Luck, Old Salt

I have trained numerous mechanics to do it. I have also done it myself many times, almost all successful. Ball, gates, checks, float, diaphragm and butterfly mostly but a few other types.

Good Luck, Old Salt

So, tell me, why are you asking me instead of your local valves distributor directly, Mildred?
