Q941y hard seal floating electric ball valve PN16 ~ pn63 is operated by electric, and the connection mode is flange connection and floating ball through type. The sealing form is hard seal. The sealing surface of valve seat is made of cemented carbide. The nominal pressure is PN16 ~ pn63, the nominal diameter is DN 15 ~ DN200, and the applicable temperature is - 28 ~ 500 ℃. The valve body is made of carbon steel or stainless steel. Due to the use of hard seal (metal seal), this valve is especially suitable for medium with particles, solids, slurry and other media and high temperature and high pressure pipeline.
Q941y hard seal floating electric ball valve PN16 ～ pn63 is suitable for two position cut-off and adjustment. The valve is directly connected with the actuator, which is composed of fine and small electric actuator (or different types of electronic electric actuator or air piston actuator can be configured according to user requirements) and ultra short ball valve. The electric actuator has a built-in servo system, which can be controlled by inputting 4-20mA signal and 220V AC power supply without additional servo amplifier. Compared with ordinary electric ball valve, it has the advantages of compact structure, small volume, light weight, close distance between valve seat and end face flange, less material retention and superior sealing performance.

1. Be careful in installation and construction, and do not hit the valve.
2. Before installation, the ball valve should be inspected to check the specification and model, and identify whether there is damage, especially for the valve stem. Turn it a few times to see if it is skewed, because Zui is prone to bump the stem during transportation. Also remove the debris in the valve.
3. When lifting the ball valve, the rope should not be tied to the hand wheel or the valve stem to avoid damage to these parts, but should be tied to the valve body.
4. The pipeline connected to the ball valve must be cleaned. Compressed air can be used to blow away iron oxide chips, mud and sand, welding slag and other impurities. These debris, not only easy to scratch the sealing surface of the ball valve, in which large particles of debris (such as welding slag), but also block the small valve, so that its failure.
5. The position of valve handle rotation should be reserved during installation. 6. The ball valve cannot be used as throttling. 7. The ball valve with transmission mechanism shall be installed vertically.
