MANUAL OPERATING LEVER
All NVMZ Series motorised Valves are equipped with a manual operating lever. This lever:
Allows the valve to be opened for system flushing before it is put into operation
Prevents damage to the seating paddle on 3-way valves, and allows flushing of the system by
maintaining the valve in the mid-position
Resets to normal position the first time the valve is powered up.
FAQ
Q1: What after-sales support do you provide for international buyers?
We offer online technical support, installation guides, spare parts supply, and quick response service to ensure smooth operation for our global partners.
Q2: What is the difference between a damper actuator and a valve actuator?
A damper actuator controls airflow in ducts, while a valve actuator regulates water or gas flow in pipelines. Both are essential in HVAC automation, but serve different functions.
Q3. How fast is the delivery time for bulk damper actuator orders?
Standard lead time is 2–4 weeks, depending on order quantity and customization. We also keep stock for fast delivery of popular models.
Q4.How should damper actuators be installed and maintained?
Installation is simple, with universal mounting brackets and clear wiring diagrams provided. Minimal maintenance is required-just periodic inspection to ensure smooth damper operation.
