KDV WEIR TYPE DIAPHRAGM VALVE
MiniVal Mini Diaphragm Valve
KDV MiniVal is a compact mini diaphragm valve designed for reliable, bi-directional flow control in applications where space and process isolation are important. Its diaphragm design isolates line media from the valve’s mechanical components while providing bubble-tight shutoff, low fugitive emissions and easy maintenance.
FEATURES AND BENEFITS
- Bubble-tight shut off
- Easy/low maintenance
- Readily available spare parts
- In-line serviceable (top entry)
- Excellent control characteristics
- Low fugitive emissions
- No stem leakage
- Line media isolated from valve mechanicals
Applications for MiniVal Diaphragm Valves
- Water and waste water
- Gases (e.g. compressed air)
- Lubricating oil
