PUBLISHED PRODUCT
Use KLS when the buyer asks for a stainless pilot piston solenoid valve for steam, air, water, light oil, mildly corrosive media or chemical-fluid service and can provide connection size, normal state, seal material, voltage and coil protection requirement.
Ordering Code Product configuration
KLS150-15-NO-V-D1-AC220V-G - KLS: Kailing stainless pilot piston solenoid valve
- KLSL: Kailing stainless pilot piston solenoid valve family reference
- 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
KLS ordering checks
The main catalog now provides the ordering structure, technical table, NC/NO dimensions, structure parts and pressure tables across pages 29-32. JHClaw should keep these as editable tables rather than flattening them into paragraph text.
Coil and seal matching
D-series DIN coils, W lead-wire coils, explosion-proof coils, waterproof coils and energy-saving coils must be selected together with seal material, model size, normal state, voltage and operating pressure.

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.
