Kailing KLS direct acting stainless solenoid valves are used when the buyer needs zero-pressure-differential starting, fast switching and compact stainless construction for steam, air, water, oil or selected chemical-fluid applications.
- 01 Zero-pressure start
Direct acting construction supports starting at zero pressure differential, with fast switching and smooth operation.
- 02 Compact stainless construction
The compact SUS304 valve body is designed for low weight and convenient disassembly.
- 03 Seal and media options
Rubber seals support lower-pressure sealing, while PTFE seal options cover a broader range of industrial media.
- 04 Industrial coil options
The catalog specifies Class H coil heat resistance and lists protection options for demanding installations.
KLS030-08-NO-V-D1-AC220V-G - KLS: stainless small direct acting solenoid valve
- 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
Zero-pressure and vacuum-compatible use
The catalog states that KLS valves start at zero pressure differential, switch quickly, start smoothly and can pass vacuum, which makes them different from pilot-operated valves that need pressure differential.
Seal and media selection
Rubber seals are suited for lower-pressure sealing, while PTFE is listed for multiple industrial media. Confirm medium chemistry, temperature and pressure before selecting seal material.
