Needle Valve Lock Off (NVLO) is a simple device for preventing inadvertent or unauthorised operation of needle valves. If you need to interlock with other valves (or devices) refer to our Needle Valve Interlock.
The device is designed to replace the existing wheel/handle. When fitted, NVLO spins freely. Valve operation can only take place when the magnetic coded key is inserted into the device, engaging the drive.
NVLO is supplied with a bespoke stem adaptor to create a precision fit of the device on the valve. For pricing on this device please provide the following information:
- Valve make
- Valve figure no.
- Valve stem size/shape
