Description

1/8" & 1/4" Stainless Steel Solenoid Valve 0–30 Bar – JA Series


Compact Direct Acting Stainless Steel Solenoid Valve for Air, Water, Gas, Oil & Vacuum

The JA Series is a compact 2/2 way normally closed direct acting stainless steel solenoid valve designed for reliable control of air, water, gases, vacuum and light oils. Its direct acting design allows operation from zero bar differential pressure, making it ideal where pressure-assisted valves cannot be used.

Manufactured from AISI 303 stainless steel with stainless steel internal components, the JA Series offers excellent corrosion resistance, fast response times and working pressures up to 30 Bar when fitted with the optional high-power coil. Available in 1/8" and 1/4" BSPT ports with multiple seal materials, it is a popular choice for OEM equipment, instrumentation, automation and compact industrial installations.

Features

✓ Direct acting operation from 0 Bar
✓ Working pressure up to 30 Bar
✓ Compact stainless steel body
✓ Air, water, gas, oil and vacuum compatible
✓ Fast 10–20 ms response time
✓ Viton, EPDM or NBR seal options
✓ 100% continuous duty rated coil
✓ IP65 protection as standard
✓ Optional high-power coil for higher pressures
