Q941RF-25P Explosion proof Electric Cut off Ball Valve_Q941F-40P electric explosion-proof O-type ball valve

Model: Q941RF-16P, Q941RF-25P, Q941RF-40P

Overview of Electric Ball Valve:

Electronic Ball Valve is a type of rotary ball valve with a 90 ° angle. It has excellent sealing performance, high flow capacity, low flow resistance coefficient, simple structure, easy maintenance, and long service life. The valve body channel and connecting pipe diameter are equal and form one diameter, and the medium 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 fields such as petroleum, chemical, metallurgical, light industry, papermaking, power plants, refrigeration, etc.

Main component materials of electric ball valve:

1. Valve body: carbon steel, stainless steel

2. Sphere: 2Cr13+nitrided treatment, 304, 316, 316L

3. Valve stem: 2Cr13, 304, 316, 316L

4. Sealing rings: polytetrafluoroethylene (PTFE), reinforced polytetrafluoroethylene (PPL), para polystyrene, flexible graphite

5. Packing: V-shaped PTFE, flexible graphite

6. Bracket: Carbon steel, stainless steel

Features of electric ball valve:

1. Low fluid resistance, ball valve is one of the types of valves with low fluid resistance, even for reduced diameter ball valves, its fluid resistance is quite small.

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 valve seat has good sealing performance and is made of sealing rings made of materials such as polytetrafluoroethylene. The structure is easy to seal, and the sealing ability of the ball valve increases with the increase of medium pressure.

4. The valve stem seal is reliable. As the valve stem only rotates and does not move up or down, the packing seal of the valve stem is not easily damaged, and the sealing ability increases with the increase of medium pressure.

5. Due to the good self-lubricating properties 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 bottom mounted valve stem and the protruding step at the head of the valve stem prevent the valve stem from spraying out. In the event of a fire causing damage to the valve stem seal, the protruding step can also form a metal contact with the valve body to ensure the valve stem seal.

Application of electric ball valve:

The Q941F-40P electric explosion-proof ball valve is an explosion-proof electric cut-off ball valve composed of an explosion-proof electric actuator and a fireproof and anti-static floating ball valve. It is a type of pipeline pressure component in industrial automation process control, which is driven by an AC 220V or DC 24V power supply to drive the actuator motor and rotate the axis of the valve stem. It is usually used for remote opening and closing (connecting and cutting off) control of pipeline media.Q941RF-25P Explosion proof Electric Cut off Ball ValveAccepting input and output of current or voltage signals from industrial automation control (DCS, PLC systems) instruments can achieve proportional adjustment or two position switch control of fluid media in process pipelines, thereby achieving automatic control of parameters such as flow rate, pressure, temperature, and liquid level of fluid media.
