Brass Control Valve (VB300)

Applications:
VB300 brass valve is equipped with electrical control device, It is made up of actuator, valve body, valve seat, paddle, stem. It can be used to control the flow of steam or cool/heating water in central air conditioning, heating, water handling and industrial processing system.

CHARACTERISTICS
Flowing Characteristics: Equal percentage
Leakage: Less than 0.05% of Kv factor
Closing Direction: Valve stem goes up is closing
Pipe Connection: G/BSP

INSTALLATION AND DEFEND
1. Before mounting the valve, make sure that the pipe is clean and free from soldering scraps, metal sheet, sand, and other sundries.
2. The pipe and valve body must be connected perfectly without vibration, The water flow direction shall be the same as marked on the valve body.
3. If the valve is mounted in the factory, which is working with high temperature fluid(steam, overheated water, diathermic liquid), it is necessary to use expansion joint to avoid expanding the pipe and pressing the valve
4. The actuator shall be mounted vertically on the valve body, and avoid the actuator is below the valve body. Remain enough space so that the actuator can be taken down from valve body during daily maintenance.
5. Power supply must be shut off or insulated when maintaining the valve, no pressure in the water system
6. For other installation requirements, please refer to our instruction to valve and actuator.
