Mixproof seats travel as a Flux 3 pair, not another ball-valve turn

ball-valve-oem, gate-valve-oem, and butterfly-valve-oem already shipped. Mixproof is two seats and a leak-detection port on the same body: closed, then both seats lifted. Flux 3 first-last at 9cr. Do not regenerate port size.

A mixproof listing is not a handle that snaps ninety degrees. It is two independently actuated seats in one body, a leak-detection port between them, and a travel you can photograph twice: both seats down, then both seats lifted. Interpolation between those two stills is the ad. A generated body that fattens the port on the way open is a different valve.

Two seats, one leak-detection port, same body

Procurement is matching a hygienic double-seat: this casting, this actuator stack, this drain nipple on the leak chamber. Closed is both seats down, chamber draining to atmosphere so two products cannot mix. Open for transfer is both seats lifted on that same body. Photograph that pair. Do not prompt a cousin mixproof with a prettier polish and a different drain.

Ball valves quarter-turn from closed to open on the same body already spent handle-across, handle-in-line. Rising-stem gates are a handwheel pair, not a foundry film already spent stem-down, stem-up. Butterfly OEM already spent disc travel in a photographed wafer. Do not twin any of those.

Keep the leak-detection port large in frame. That nipple is the claim this is mixproof, not a single-seat cousin. If the still hides the port, the interpolate will not invent an honest one. Crop people. Crop a dairy hall you did not film.

Closed, then both seats lifted

Photograph the valve square-on, or at the three-quarter you already print on the cut sheet. Both seats down. Drain visible. That is frame A. Do not touch the tripod. Lift both seats to the open position you sell. Same body, same end connections, same leak-detection port. That is frame B.

First-last frame takes those two stills and generates the motion between them. Ordinary image-to-video improvises the ending. First-last has to land. The two frames have to be connectable: same serial, same actuator stack, same lens height, same lighting family. A closed 2-inch mixproof into an open 3-inch cousin is a morph of the SKU.

Prompt the travel, not the objects. "Both seats lift on the same body, leak-detection port static, camera locked, no new flanges." Re-describing "hygienic double-seat mixproof, 2 inch, EPDM" restages the hardware. The stills already contain the class.

Do not treat a loop (same still in both slots) as a mixproof demo. A loop is ambient motion on one plate. This offer needs two states. Seat-lift CIP — one seat rising while the other stays down — is a different pair. Shoot that pair if that is the week. Do not ask closed-to-both-lifted to invent a one-seat CIP on the way through.

Flux 3 at 9cr; Veo first-last is the short 4K row

Create a first-and-last-frame transition video is the named agent job: two photos in, one transition out. The agent passes them as first and last frame and picks a first-last-capable model. Cost is priced per model, shown before you confirm. This is not the plain "turn one photo into a video" capability.

Flux 3 First Last Frame to Video is the interpolation row: start frame and end frame, native audio, up to 1080p, 5s through 20s. The listed rate is 9 credits per second. Audio is on — write the mix (a quiet bench, an actuator click, no speech) or write silence. A silent brief still gets a soundtrack you did not choose.

VEO First Last Frame interpolates first and last frames: requires an image, native audio, 4s / 6s / 8s, up to 4K, listed 40 credits. A seat lift does not need a cinematic mouth. Write the mix or write silence. Eight seconds of 4K on Veo if the specifier will pause on the drain nipple. Ten to twenty seconds on Flux 3 if both seats need time to read. Do not stitch both rows. Stitching is how the port breathes.

Inspect the midpoint. Ends are held by construction. The middle is where a generator cheats — extra packing, a second drain, a port that fattens. If the middle is wrong, reroll the motion, not the stills, unless a still was the lie. Overlay the figure number after picture lock. Do not ask the interpolate to typeset DN on the body.

Not another ball-valve turn. Port size is not a prompt

A quarter-turn is a handle. Mixproof is two seats and a leak chamber. Copying the ball playbook onto this body is how a specifier never sees the drain. Copying the gate playbook — foundry pour — is a plant film you may not own.

Port size is a claim. The bore already lives in the photographs. A generate that "opens" by growing the bore is a different SKU. If a 2 becomes a 3 for six frames, throw the take out.

Order: two approved stills of the same mixproof body; first-last on Flux 3 or Veo; prompt only the seat travel. Reverse that order and you will pay for a cousin valve that changed port size on the way open. A constructed engineer walking "what you should spec for this dairy line" is a presenter you do not need. Photograph the pair.

FAQ

Can I animate one photo of the closed mixproof and hope both seats lift?

You can. The ending is then the model's guess. A mixproof ad is both seats lifted on the same body, leak-detection port unchanged. Pin that still as the last frame or you are not selling the travel.

Why Flux 3 instead of Veo first-last?

Length and ceiling. Flux 3 is 5s–20s, up to 1080p, 9 credits per second, native audio. Veo first-last is 4s / 6s / 8s, up to 4K, listed 40 credits with audio on. Same job shape: two stills, one landing. Pick by how long both seats need to read.

Is this the same as the ball-valve quarter-turn post?

No. That post is handle-across to handle-in-line on a ball. Gate is stem-down to stem-up. Butterfly is disc rotation in a photographed wafer. This leftover is two seats and a leak-detection port. Do not twin any of those three.

Do the two photos have to share the same leak-detection port?

Yes. Same body, same drain nipple, same end connections, same lighting neighbourhood. A noon still into a night still is a time-lapse you should prompt as one. A different valve is a morph. Missing the open pair is a different job.
