Actuated Valve Dimension: Face to Face
Actuated Valve Dimension: Face to Face
(OP)
Can more knowledgable persons please explain because I am not very familiar with details of valves and its dimensions.
For pneumatic actuated valves, would the face to face dimension be the same as a manual valve for a given type of valve, e.g. butterfly type?
I need the information very urgently because for the piping design but unfortunately, the valves have yet to be ordered, but the piping isometrics need to be done.
Appreciate any information, please.

and has no impact on face-face dimensions.

>> from the same manufacturer
>> within the same series
>> with the same trim
typically have the same face to face dimension...
... but there is no law requiring this to be so.
At your apparent level of responsibility, you probably need to get someone in authority to commit to the basic valve dimensions, or to at least verbally accept the business risk that comes with changing valve size/series/trim/mfgr after the pipes have been committed to fabrication.

The face to face dimension for other valves will be as per ASME 16.10.
i think i have cleared for your query.

Regardless, the actuator for a shutdown valve (scotch yoke style) could be substantially larger than the face-to-face. Assure that the piping layout accommodates the actuator including access to any valve mounted control accessories.

now Industries also use IEC 60534-3 standard for face to face dimension
