VBN Butterfly Valve With Micro Adjust Handwheel

Micro Adjust Butterfly Valve is infinitely adjustable. Perfect for those situations where precision flow rates are required, such as process piping between lauter tun and the grant. Stainless handle and spindle assembly are durable and rounded to prevent

Application

Micro Adjust Butterfly Valve is made of SS304/SS316L and is infinitely adjustable. Micro Adjust Handwheel is a very unique valve that allows you to dial in the precise flow that you require for your application.

We offer this valve in sizes 1″ to 4″ with either Silicone, EPDM or Viton seats
