Pilot for PRV or direct acting pressure reducing valve

Pilot for PRV or direct acting pressure reducing valve

Pilot for PRV or direct acting pressure reducing valve

(OP)
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

RE: Pilot for PRV or direct acting pressure reducing valve


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.
