Explosion proof electric ball valve _Q941F-40P electric explosion-proof ball valve
Model: Q941RF-16P, Q941RF-25P,Q941RF-40P
Overview of electric ball valve:
Electronic Ball Valve is a kind of rotary ball valve with a 90 ° angle. It has excellent sealing performance, large flow capacity, small flow resistance coefficient, simple structure, convenient maintenance, long service life, equal diameter of valve channel and connecting pipe, and media can flow almost without loss. Q941F-40P electric explosion-proof ball valve is usually used in occasions with strict sealing requirements. In addition to controlling gas, liquid and steam media, it is also suitable for controlling sewage and media containing fibrous impurities. It is widely used in petroleum, chemical industry, metallurgy, light industry, paper making, power station, refrigeration and other work fields.

Main parts and materials of electric ball valve:
1. Valve body: carbon steel, stainless steel
2. Sphere: 2Cr13+nitrided, 304, 316, 316L
3. Valve rod: 2Cr13, 304, 316, 316L
4. Sealing ring: polytetrafluoroethylene (PTFE), reinforced polytetrafluoroethylene (PPL), para polystyrene, flexible graphite
5. Packing: V-shaped PTFE, flexible graphite
6. Support: carbon steel, stainless steel
Features of electric ball valve:
1. The ball valve is one of the valves with small fluid resistance. Even the reduced diameter ball valve has relatively small fluid resistance.
2. The thrust bearing reduces the friction torque of the valve stem, which can make the valve stem balanced and flexible for long-term operation.
3. The sealing performance of the valve seat is good. The sealing ring made of PTFE and other materials is easy to seal, and the sealing capacity of the ball valve increases with the increase of the medium pressure.
4. The valve stem seal is reliable. Since the valve stem only rotates rather than moves up and down, the packing seal of the valve stem is not easy to be damaged, and the sealing capacity increases with the increase of medium pressure.
5. Due to the good self-lubricating property of materials such as polytetrafluoroethylene, the friction loss with the ball is small, and the service life of the ball valve is long.
6. The lower mounted valve stem and the convex step at the head of the valve stem prevent the valve stem from ejecting. If the valve stem seal is damaged due to fire, metal contact can also be formed between the convex step and the valve body to ensure the valve stem sealing.

Electric ball valve application:
Q941F-40P electric explosion-proof ball valve is an explosion-proof electric cut-off ball valve composed of explosion-proof electric actuator and fireproof and anti-static floating ball valve. It is a kind of pipeline pressure element for industrial automation process control. The actuator motor driven by 220 V AC or 24 V DC power drives the valve stem axis to rotate. It is usually used for remote opening and closing (connecting and cutting off media) control of pipeline media. The explosion-proof electric ball valve receives the input and output of the current signal or voltage signal from the industrial automation control (DCS, PLC system) instruments, and can realize the proportional regulation or two position switch control of the fluid medium in the process pipeline, so as to achieve the automatic control of the flow, pressure, temperature, liquid level and other parameters of the fluid medium.
