Pneumatic three-way ball valve Q614F-16P

Pneumatic Three way Ball Valve Q614F-16P Product Description

Pneumatic three-way ball valve Q614F-16P is suitable for automatic switching, switching or process control conditions in small caliber equipment, sampling branches, automation matching and public engineering. 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

Q614F-16P adopts T type three-way flow channel, internal thread connection, and floating ball structure. During operation, the opening and closing components are driven by double acting or single acting pneumatic actuators to change the flow cross-section, achieving three-way diversion, merging, or reversing; If continuous proportional adjustment is required, the ball flow channel, valve seat, and positioning control configuration should be confirmed separately. 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 air source pressure, control signal, single or double acting requirements, safety position for gas loss, and power supply conditions (such as configuration) of accessories such as solenoid valves or positioners should be clearly defined during the ordering stage to avoid inconsistency between accessory interfaces and on-site control logic.

Caliber pressure and material selection

The commonly used nominal diameter is DN15-DN50, and the pressure rating is PN16/PN25. The valve body material can be selected as CF8/CF8M, 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 three-way diversion and merging, threaded connection, and fast action. After reasonable configuration, it can be used for small caliber equipment, sampling branches, automation matching, and public works. 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; If solenoid valves, locators or limit switches are configured, their electrical interfaces should be protected according to the on-site environment; Pneumatic accessories should use a clean and dry air source that meets the requirements of the actuator. 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 air source, filter pressure reducing device, solenoid valve or positioner (if configured), valve position feedback and pneumatic actuator should be checked first, and then the valve stem, valve seat and seals should be checked. Blindly increasing the driving force is not advisable. 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.

Q614F-16P Pneumatic Three way Ball Valve Common Problems

Is Q614F-16P a T type flow channel?

The current page parameter is clearly T type three-way flow channel, and the actual interface connection position should still be confirmed during ordering.

Can a three-way ball valve be directly used as a continuous control valve?

It cannot be judged solely by pneumatic actuators. Continuous adjustment requires confirmation of the ball flow channel, valve seat, allowable pressure difference, and positioning control configuration.

How to choose between single acting and double acting actuators?

It should be determined based on whether a loss of air reset is required, the frequency of action, the required torque, and the safe position of the system.

Order Information List

Suggest providing the composition of the medium, design and operating temperature, maximum and normal pressure, flow range, pipeline standards, operating frequency, control signals, power or gas supply conditions, fail safe location, and environmental protection requirements. Fouten Flow Control (Jiangsu) Co., Ltd. will verify the caliber, material, seal, actuator, and accessory combination based on these materials to ensure that the product parameters are consistent with the actual pipeline conditions, and provide traceable basis for subsequent installation and maintenance.
