Pilot for PRV or direct acting pressure reducing valve

[Baram]

Hi Our Experts,

I have pilot operated pressure reducing valves 6" , brand is
,pilot model 1340 , pilot spring range 20-80 psi is damaged,
My question is : can I use another manufacturer for directing acting pressure reducing valve size 1/2" instead of the pilot.
pilot port size is 1/2".
In another way can we replace damaged pilot (2 way) for PRV to another manufacturer for direct acting pressure reducing valves? also another concept.

The problem I face that the price of pilot as spare part is higher than direct acting PRV.

NOTE. I will try to find same spring stiffness for to keep 20-80 psi.

Also you can find the attached files.

Thanks,
Baram

I would avoid using 'creative' solutions, using un-original spares or other models to do a regulating job, chances are that you very easily could come into problems costing far more than the saved sparepart price.

Bear in mind that to have a satisfactorily working regulating valve you have to have a solution both installed correctly, and covering the complete working range of the actual situation.

If the one valve/brand/type you have has worked properly: keep it, replace with original spares.

Note: if the pilot spring has broken prematurely the whole valve could have been dimensioned or installed incorrectly, in which case you should re-evalute and replace existing solution totally, and perhaps with even a more advanced valve regulating system.

Quality costs, but price over lifetime could be far better with a proper solution, costing more to buy.

Baram, a ½-inch direct acting pressure reducing valve should work the same as the OCV pilot. I am assuming a water application.
