LENO MSV-O Manual Presetting Valve
Brand: DanfossLENO MSV-O is a new generation of manual valves for balancing flow in heating, cooling and domestic hot water systems.
It is recommended to use LENO™ MSV-O in constant flow systems in front of boilers, flat stations or heat pumps in one-family houses for balancing, shut-off function for service and repair, flow verification, one pipe systems.
The valve may be mounted in flow or return.
LENO MSV-O is a combined presetting and shut off valve with a range of unique features:
- Fixed Venturi Orifice
- Removable Hand Wheel for Easy Mounting
- Numeric Presetting Scale, Visible From More Angles
- Easy Locking of Presetting
- Open-Close with Allen Key in Emergency
