Hello everyone,

 

I found in this vendor link 700001-2.pdf (ari-armaturen.com).

 

I saw different Kvs value for this certain control valve. 

Please see the attached screenshot,

 

there are 2 Kvs values: standard and reduced. By reduced, they mean Kvs value for a different opening?

I am not familiar with this vendor, so I'd recommend calling them and asking how they achieve the reduced Kv's.

 

The vendors I am familiar with achieve reduced Kv's using different "trim", which changes the opening.  Another vendor I am familiar with has a built-in Kv adjustment knob on their eccentric plug control valve.

 

So, give them a call/e-mail.

Hi Latexman,

Thanks for your reply!
Yes, I will call try to contact them.
Then there is a way that changes the opening, which reduces the Kvs.
