PUBLISHED PRODUCT
Use KLSL for stainless steam-type pilot piston solenoid valve inquiries where the buyer names KLSL or needs steam-capable fluid-control selection.
Ordering Code Product configuration
KLSL150-D1-AC220V - KLSL: stainless pilot piston steam-type family
- NO: normally open variant where listed
- Select the catalog size that matches pipework, flow and pressure requirements
- Blank: normally closed where applicable
- NO: normally open where listed
- PTFE, NBR, EPDM, VITON, silicone or custom option depending on series evidence
- Confirm coil connector, protection requirement, voltage and frequency
Pressure depends on coil and voltage
Do not quote KLSL by size alone. Confirm KLSL model, normal state, coil type, voltage, pressure and media temperature together.
Steam service caution
For steam or high-temperature applications, confirm seal compatibility, pressure and duty cycle before replacing a standard fluid solenoid valve.

Frequently Asked Questions
- FAQ What information is needed before quoting this valve?
Confirm medium, temperature, pressure, port or flange size, normal state, seal material, body material, voltage, coil protection requirement and quantity. - FAQ Can this series be used for corrosive or chemical fluids?
Some catalog rows mention slightly corrosive or chemical fluids, but the exact medium concentration, temperature and seal compatibility must be checked before selection.
