Dimensions (All Dimensions are in mm) Attention: Please read the instruction manual, check the product model and parameters before installation, and set the working voltage and input signal according to the requirement;

Ensure vertical installation, reserved space to facilitate maintenance；

The installation should pay attention to ensure that the direction of flow with the arrow pointing on the body consistent;

The proposed design system bypass connectivity, filling should bypass the impurities in the pipeline clean, otherwise it may cause valve blockage;

System shutdown and system filling, should be set to normally open state (refer to module operation instructions);

The installation should be guaranteed before and after the valve reserved for a length of straight pipe section, usually in the reserved pipe diameter of 10 times the length of the straight pipe, export reserved pipe diameter 5 times the length of straight pipe section;

Installation:

Downward Installation Prohibited

Notice: When we do the pipe pressure testing and flushing, the valve body should be in a state of full open. This operation can not only protect the internal parts of valve body, but also prevent pipe from blocking. pipeline

Maintenance：

When doing service work on the actuator: Close the pump and turn off the power supply. Close the shut-off valve, exhaust water in the pipe to

reduce the pressure inside pipes. Make water pipe(hot water) cool down naturally.

Dismantle electric wires from wiring terminals.

Remark: Before debugging valve again, install actuator correctly.

Downward installation is forbidden, when the medium is chilled/hot water and the flow direction of medium in valve should be consistent with the medium of Pipe Line

INTELLIGENT ACTUATOR

LEHRY intelligent actuator is a kind of electronic and mechanical product; it can be matched with 40MM & above size valve body by different connectors.
