Electric three-way ball valve Q944F-16P

Electric Three way Ball Valve Q944F-16P Product Description

The electric three-way ball valve Q944F-16P is designed for automatic switching or process control needs in water treatment distribution, chemical batching, equipment bypass, and utility engineering. When selecting, one should start from the actual working conditions, check the medium name, temperature, maximum and normal flow rates, pressure before and after the valve, connection standards and control methods, and not simply copy the valve diameter based on the existing diameter. The parameters provided in this article belong to the commonly used configuration range, and the final execution data should be based on the project operating conditions, order confirmation form, and manufacturing drawings.

Product Specifications

Structure and working mode

Q944F-16P adopts L type three-way flow channel, flange connection, and floating ball structure. When the fluid passes through the valve body flow channel, the position of the opening and closing parts is changed by the angular stroke electric actuator, thereby reversing and opening and closing between the two designed flow paths; If special intermediate valve position function is required, it should be confirmed according to the actual ball opening and actuator limit. The actuator should match the required torque or thrust of the valve and have a reasonable safety factor. When there are requirements for feedback, positioning, or interlocking, it is necessary to specify the power supply, control signals, valve position feedback, and electric actuator requirements during the ordering stage to avoid inconsistent on-site accessory interfaces.

Caliber pressure and material selection

The commonly used caliber is DN15-DN200, and the pressure rating is PN16/PN25. The valve body material can be selected as CF8/CF8M, but the material selection cannot be separated from the corrosiveness of the medium, chloride ion content, temperature fluctuations, and cleaning conditions. PTFE or enhanced PTFE soft seal, its allowable temperature, pressure difference, and leakage level need to be checked simultaneously. For steam, crystallization prone, particle containing, or frequent operating conditions, further confirmation should be made on the hardness of valve internals, packing form, and erosion prevention measures.

Product features and applicable industries

The main features of this product are three-way reversing, remote switch, and L flow path. After reasonable configuration, it can be used for water treatment distribution, chemical batching, equipment bypass, and public works. When used in hazardous areas, the corresponding actuator, solenoid valve, limit switch or locator should be selected according to the explosion-proof zone on site; When used in food, pharmaceutical and other systems, it is also necessary to confirm the requirements for liquid handling materials, surface treatment and cleaning. Any project involving oxygen, strong corrosive or toxic media should undergo specialized material and safety reviews.

Installation and Debugging

Before installation, check the nameplate, flow direction, flange or thread standards, remove welding slag and hard debris from the pipeline, and ensure that the front and rear pipe sections are concentric to avoid transmitting pipeline stress to the valve body. Space for disassembly and assembly should be reserved around the actuator, and cable entrances should be waterproofed and protected according to the on-site environment. The first debugging should check the fully open and fully closed positions, travel feedback, interlocking logic, and sealing conditions under low-risk conditions, and then gradually enter the working pressure.

operation and maintenance

During operation, the action time, abnormal noise, leakage, valve position feedback, and control signals should be observed. If the action is slow, first check the power supply, wiring, control module, valve position feedback, and electric actuator, and then check the valve stem, valve seat, and seals. It is not advisable to blindly increase the driving force. Before maintenance, it is necessary to isolate the medium, relieve pressure, and confirm that the equipment has no residual energy. After replacing the seal, strength, sealing, and action tests should be conducted according to regulations, and the material of the spare parts and the date of maintenance should be recorded.

Q944F-16P electric L three-way ball valve common problems

Is the L three-way ball valve mainly used for diversion or reversing?

The L type flow channel is usually used for reversing between two flow paths, and the actual interface connection relationship should be confirmed based on the spherical opening and installation direction.

Can Q944F-16P achieve all flow paths of T three-way ball valve?

No. The internal flow channels of L and T are different, and should be selected separately according to the required connection method.

Can the middle position of the electric three-way ball valve be set freely?

No, it should be determined based on the combination of ball flow channel, actuator limit, and valve position allowed by the process.
