Product Overview
The SZW-10K-24VDC is a heavy-duty 3/8" 304 stainless steel solenoid valve engineered for fail-open, zero-differential fluid control in 24V DC industrial and battery-powered systems. Featuring a Viton® (FKM) diaphragm seal and a direct-assisted lift mechanism, this 2-way Normally Open (N/O) valve remains open when de-energized to permit unrestricted flow at 0 PSI, closing in less than one second when 24V DC power is applied.
Normally Open Application & Media Notice:
-
-
- This valve is Normally Open (remains open when de-energized and closes when energized). It is designed specifically for fail-open setups, gravity-fed drains, freeze/overheat protection loops, and safety bypass lines.
- Equipped with a Viton® (FKM) diaphragm rated for media up to 250°F, diesel fuel, glycol, weak acids, and harsh fluids.
- Always verify chemical compatibility before installation.
-
Key Features
-
304 Stainless Steel & Viton® Construction: Maximum chemical, corrosion, and temperature resistance for aggressive media, potable water, and outdoor environments.
-
Normally Open (Fail-Open) Operation: Keeps fluid flowing or lines drained during power loss—essential for emergency dump lines, cooling loops, and safety circuits.
-
24V DC Automation & Battery Integration: Connects directly into 24V DC PLCs, industrial control boards, solar controllers, and 24V battery banks using an IP65-rated DIN electrical connector.
-
Zero Differential Operation: Direct-assisted design operates reliably from 0 PSI (gravity feed) up to maximum working pressure.
-
Fast-Acting & 100% Duty Cycle: Closes in under one second when energized and rated for continuous-duty operation.
Common Applications
-
PLC-driven industrial automation, safety bypass loops, and machine tool cooling lines
-
Solar thermal overheat dump lines, gravity-fed water tank drains, and reservoir dumping
-
24V DC battery-powered irrigation, fertigation flushes, and remote fluid management
-
Auxiliary diesel fuel transfer bypass, generator fuel lines, and glycol circulation
-
Commercial beverage equipment, high-temp sanitizing dump lines, and gas purge loops
Installation
- Align media flow with the directional arrow cast into the 304 stainless body.
- Connect 24V DC power using the included DIN electrical connector.
- For optimal service life and reliable seal closure, especially in gravity-fed drain lines, mount the valve with the coil facing upward.
- Install an inline strainer upstream to keep sediment off the Viton® diaphragm.
