Overview of Q641H Q641H-16 Q641H-16C Q641H-16P Pneumatic ball valve

Q641H Q641H-16 Q641H-16C Q641H-16P Pneumatic ball valve is suitable for two position cut-off and adjustment. The connection between ball valve and actuator adopts direct connection mode. Pneumatic metal sealed ball valve is suitable for working conditions with temperature above 250 ℃. Pneumatic metal seal ball valve is mainly divided into two sealing structures: one-way seal and two-way seal; One way sealing: it can only be sealed in the specified direction, that is, the sealing direction marked by the ball valve; Two way sealing: it can be sealed in both directions; The structure of pneumatic hard seal ball valve is divided into floating ball type and fixed ball type; The connection forms are flange connection, welding connection and threaded connection. Matched with the electric valve positioner, the operation can be controlled by inputting 4 ~ 20mADC signal and 0.4 ~ 0.7MPa air source to realize the adjustment of pressure, flow, temperature, liquid level and other parameters.

Features of Q641H Q641H-16 Q641H-16C Q641H-16P Pneumatic ball valve

1. Q641H Q641H-16 Q641H-16C Q641H-16P Pneumatic ball valve has small fluid resistance, which is the smallest of all valves. With compressed air as power, the regulating type can control the operation by receiving (4-20mA, 0-10mA or 1-5vdc) current signal or voltage signal. The switch type accepts a simple contact model to perform switching action. Q641f pneumatic ball valve rotates the ball 0 ~ 90 º with the torque output by angular stroke to achieve opening and closing action or adjustment action.

2. The ball core channel of Q641H Q641H-16 Q641H-16C Q641H-16P Pneumatic ball valve is flat and smooth, and it is not easy to deposit media. Pipeline ball passing can be carried out. The utility model has the advantages of simple structure, light weight and good sealing performance. Q641y / h pneumatic hard seal ball valve is especially suitable for occasions requiring zero leakage rate.
