Electric corrosion-resistant ball valve Q941F-10P

Electric corrosion-resistant ball valve Q941F-10P Product Description

The electric corrosion-resistant ball valve Q941F-10P is suitable for automatic switching, switching or process control in electroplating, environmental protection, chemical wastewater and water treatment systems. Before determining the configuration, a comprehensive judgment should be made based on the composition of the medium, operating temperature, maximum and normal flow rates, pressure before and after the valve, connection standards, operating frequency, and control signals. The model cannot be directly determined based solely on the existing pipe diameter. The following parameters are commonly used configuration ranges, and actual supply should be based on project conditions, technical confirmation forms, and manufacturing drawings.

Product Specifications

Structure and working mode

Q941F-10P adopts a two-piece straight channel, flange connection, and floating ball structure. During operation, the angle stroke electric actuator drives the opening and closing components to change the flow cross-section, achieving cutting, reversing, or adjustment. The actuator should be selected according to the maximum pressure difference, valve stem thrust or output torque, and a reasonable margin should be reserved. When remote feedback, proportional adjustment, or interlocking is required, the requirements for power supply, control signals, valve position feedback, and electric actuators should be clearly defined during the ordering phase to avoid inconsistencies between accessory interfaces and on-site control logic.

Caliber pressure and material selection

The commonly used nominal diameter is DN15-DN200, and the pressure rating is PN10/PN16. The valve body material can be selected from PPH or UPVC, and its adaptability needs to be confirmed in combination with the corrosiveness of the medium, temperature cycling, particle content, and external environment. The allowable temperature, pressure difference, and leakage requirements of PTFE soft seal should be checked synchronously. For pipelines that are prone to crystallization, contain particles, frequently move, or have significant temperature changes, the wear resistance of valve internals, packing structure, support method, and erosion prevention measures should also be confirmed.

Product features and applicable industries

The main features of this product include corrosion resistance, remote switch, and flange connection. After reasonable configuration, it can be used for electroplating, environmental protection, chemical wastewater and water treatment systems. When dealing with flammable, explosive, highly corrosive, high-temperature, or toxic media, explosion-proof actuators, locators, solenoid valves, limit switches, and corresponding materials should be selected according to site specifications, and general parameters should not replace special safety reviews.

Installation and Debugging

Before installation, the nameplate, flow direction, connection standard, and sealing surface should be checked, welding slag and hard debris in the pipeline should be removed, and the front and rear pipe sections should be ensured to be concentric. It is forbidden to use valves to forcibly correct pipeline deviations. Maintenance space should be reserved around the actuator, and cable entrances should be waterproofed and protected according to the on-site environment. The first debugging should be carried out under low-risk conditions to check the fully open and fully closed positions, travel feedback, interlocking logic, sealing condition, and abnormal noise, and then gradually increase to the working pressure.

operation and maintenance

During operation, action time, valve position feedback, leakage, pressure difference, and control signals should be recorded. If the action is slow or the switching is not in place, the power supply, wiring, control module, valve position feedback, and electric actuator should be checked first, and then the valve stem, valve seat, and seals should be checked. It is not advisable to blindly increase the driving force. Before maintenance, it is necessary to isolate the medium, relieve pressure, and confirm that there is no residual energy; After replacing the seals, conduct strength, sealing, and action tests according to regulations, and keep records of spare parts materials and maintenance.
