Typical Applications
The VHS30-N03-Z is ideal for pneumatic systems requiring:
- Pressure relief and system isolation during maintenance shutdowns
- Energy isolation systems for machine safeguarding
- Modular air preparation assemblies with FRL components
- Industrial control and automation systems
- Equipment where manual lockout is required for compliance
Compatibility & Replacements
Compatible With
- SMC modular spacer assemblies for FRL (filter-regulator-lubricator) stacking
- Standard pneumatic 3/8″ NPT female port systems
- Compressed air distribution networks rated 0.1–1 MPa
- OSHA-compliant energy isolation and lockout procedures
Replaces / Drop-In Replacement For
The VHS30-N03-Z directly replaces other VHS30 body size manual lockable variants when NPT threading and PSI labeling are specified. Verify exact port configuration and pressure label requirements with your system integrator before ordering.
Works With
