How should I choose diaphragm and valve-seat materials?

Provide the reagent and cleaning-fluid composition, concentration, temperature and contact time. Check all wetted parts together: diaphragm, O-rings, base plate and, on threaded versions, the valve seat. A material name alone does not establish compatibility with every fluid.

Are 12 V DC and 24 V DC solenoid valves available?

Yes. The SV10 series offers separate 12 V DC and 24 V DC versions, each with ±10% voltage tolerance. Select the coil for your equipment supply. Standard power is 2.5 W; the optional power-saving circuit uses 2.5 W at start and no more than 1 W while holding. Observe polarity: red positive, black negative.

How quickly does the valve respond?

Response is ≤15 ms for the standard version and ≤25 ms with the power-saving circuit under no-load test conditions at 25 °C, rated voltage and maximum operating air pressure applied to the common port. Actual timing varies with the circuit and fluid. FFKM diaphragms respond more slowly at temperatures of 15 °C or below.

Q: Should I choose a normally closed or normally open solenoid valve?

Choose the valve according to what your equipment needs when power is removed. A normally closed solenoid valve closes the connection without power and opens it when energized. A normally open solenoid valve does the reverse. The SV10 series offers NC and NO options for its 2-way valves.

The SV10-M6/U28-2 2-way valve opens or closes a reagent or wash-fluid line. Choose normally closed operation if the line must close without power, or normally open operation if it must remain open; energizing the valve reverses that state. Coordinate the valve with the pump and instrument sequence to control delivery, and select a 12 V DC or 24 V DC coil.

Choose M6 or 1/4-28 UNF fittings to match the valve. Recommended thread engagement is 5 mm and tightening torque is 0.25–0.3 N·m. Use a suitable sealing washer at the bottom seal. EPDM, FKM or FFKM diaphragms and matching O-rings can be combined with the available valve-seat materials. Check all wetted parts against the actual reagents and wash fluids; a PFA seat or base plate requires separate configuration confirmation.

2-way solenoid valves for reagent on/off control

In an automated analyzer, a 2-way valve can open the reagent line for a dispensing step and close it afterwards. Choose NC when the connection must be closed without power, or NO when it must remain open.

Coordinate the valve with the pump and equipment program. The valve controls the connection; the pump and its operating sequence determine the amount delivered.

Power-off behavior: normally closed or normally open

Use a normally closed version when the line must close without power, or normally open when it must remain open. Consider this state as part of the equipment shutdown and restart sequence.

Equipment integration: manifold or tubing connections

Use the base-mounted version when combining valves on a fluidic manifold. Choose threaded connections for tube fittings, or barbed connections for flexible tubing.

Plan access for installation, tubing replacement and wiring. The three connection styles serve different layouts while retaining the same choices of 2-way or 3-way function.

Frequently Asked Questions

A normally closed valve closes the connection without power and opens it when energized. A normally open valve does the reverse. Coordinate the valve with the pump and control program: the valve controls the connection, while a pump or pressure difference moves the fluid.

Send the circuit diagram, 2-way or 3-way requirement, unpowered state, connection type, reagent and cleaning fluids, pressure, temperature and supply voltage. Include mounting space and cycle timing so we can match the connection, materials and power-saving option. The displayed models identify configuration families, not complete ordering codes. Confirm the operating state, voltage, diaphragm and other wetted materials, and power-saving option when ordering. M6 and U28 identify separate M6 and 1/4-28 UNF threaded versions.
