Notes
Product Overview
VE4020B1145T extends the DN20 safety shut-off valve by adding an integrated flow regulation function.
This allows commissioning engineers to fine-tune burner gas flow directly at the valve without installing additional throttling components.
It is commonly selected for burner systems where small flow adjustments are needed to optimize combustion performance while still maintaining full safety shut-off capability.
Key Features
- Normally closed safety shut-off behavior
- Integrated flow regulation for commissioning flexibility
- DN20 size for medium-capacity gas lines
- Fast response times suitable for safety applications
- IP65-rated enclosure for industrial environments
- VE4000 modular design simplifies replacement
Packaging & Delivery
- Protective industrial packaging
- Export packing supported
- Suitable for spare parts inventory
Frequently Asked Questions (FAQ)
Q: Does the flow regulator replace a pressure regulator?
A: No, it is for flow trimming only, not pressure regulation.
Q: When should I choose B instead of A type?
A: Choose B when on-site flow adjustment is required.
