API 609 Cat A Butterfly Valve
14 products found
An API 609 Cat A butterfly valve is a concentric, zero-offset rotary valve designed and manufactured in strict compliance with Category A of the API 609 standard, governing rubber-seated valves with a localized interference fit. The design features a disc centered precisely in the middle of the valve bore and stem axis, which rotates 90 Degree to press directly into a resilient rubber liner (such as EPDM, NBR, or Viton) to achieve a tight shutoff. Because the disc remains in continuous contact with the seat throughout its entire rotational stroke, Category A valves are specifically optimized for lower-pressure systems, typically rated up to Class 150 LB or PN16. Procurement managers and piping contractors can minimize project overhead and secure reliable low-pressure flow isolation by importing certified API 609 Cat A butterfly valves directly from premier manufacturers in China via our advanced B2B commercial platform.
