22*25mm Ball Valve 1704A0014 Replacement For Biesse Vacuum Cups Of CNC Machine

A ball valve is what decides whether a vacuum pod holds or releases, and when it sticks the panel either will not let go or will not hold. The 1704A0014 is a 22 mm outer diameter ball valve, 25 mm high without the ball, in black, in three parts: cap, ball and spring. It replaces the valve in Biesse vacuum pods and suction cups.

A vacuum pod that will not release a panel is as bad as one that will not hold it. The valve sticks, the operator waits for the vacuum to bleed down, and the cycle time grows a few seconds per panel until the table is the bottleneck. Nothing looks broken, because the pod is still sealing.

The 1704A0014 replaces that valve. It is a 22 mm outer diameter body, 25 mm high measured without the valve ball, in black, and it comes apart into three parts: cap, ball and spring. The 22 mm diameter is the seat figure; the 25 mm height is what has to clear the pod housing when the valve is closed.

The three-part structure is why the valve can be replaced without the pod. Cap, ball and spring are the whole mechanism: the spring returns the ball, the ball seals, and the cap holds both in place. When one of the three fails the valve behaves differently, which is why a valve that sticks is a valve that needs replacing rather than adjusting.

Packing is 500 pieces per carton, which suits a table rebuild or a service kit rather than a single replacement. Fit is checked on diameter and height against the valve being removed, and the pod model is the second reference: Biesse vacuum pods and suction cups use this valve.

What the three-part build and the two dimensions control:

• 22 mm outer diameter — the 22 mm body is the seat figure that decides whether the valve drops into the pod.
• 25 mm height, ball excluded — 25 mm measured without the valve ball; this is the clearance that has to fit under the pod housing.
• Cap, ball, spring — three parts per valve, which is the whole mechanism: seal, return and retention.
• Black body — visually distinct against a grey pod, which helps when a table has mixed valves.
• Biesse vacuum cup fit — listed as a replacement valve for Biesse vacuum pods and suction cups on CNC machines.
• 500 pcs per carton — packed for a table rebuild or a service kit rather than a single swap.
• Wear part — the spring and the ball seat are what wear out, which is why the valve is replaced as a unit.
• Two-number check — diameter and height off the old valve decide fit; the pod is the second reference.
• Seat and ball wear as a pair — the ball and the seat it seals against wear together, which is why the valve is replaced whole instead of re-using a worn seat.

What a working valve changes about a table that has become slow:

• Release stops being a wait. A sticking 22 mm valve holds vacuum after the cycle, so the operator waits for the panel to come free. A new valve releases when the circuit does.
• Seal restored where it happens. The ball and its seat are the sealing pair; replacing the valve restores that seal without opening the pod.
• Height is the fit figure. At 25 mm without the ball, the valve has to clear the pod housing; measuring it avoids a valve that threads in but sits too tall.
• Three parts, one unit. Cap, ball and spring are supplied as one valve, so there is no question of which component failed.
• Carton quantity suits a rebuild. 500 pieces per carton matches a table service rather than forcing single-unit purchases.
• Diagnosis gets simpler. When one pod holds and another does not, the valve is the first part to swap, and it is a straight exchange.
• Cycle time stops creeping. A valve that sticks adds a few seconds to every panel; across a shift that is the difference between the table being the bottleneck and not.

Check two numbers on the old valve: 22 mm outer diameter and 25 mm height without the ball. If they match, it replaces the valve in the same pod. Send the pod or machine model if you want it confirmed first.

Three parts: cap, ball and spring. The spring returns the ball, the ball seals, and the cap retains both.

The 25 mm figure is the body height with the ball removed, which is how the valve has to fit under the pod housing. Measuring with the ball in place gives a different number.

Packing is 500 pieces per carton, which suits a table rebuild or a service kit.

Either the panel will not release at the end of the cycle, or the pod takes longer to pull vacuum at the start. Both point at the valve rather than the pump.

The body is plastic, listed black. The ball and spring are inside the cap.

The valve is supplied as a complete unit of cap, ball and spring, which is the practical way to replace it because the seat wears with the ball.
