Extended Female Thread Ball Valve
If you are looking for a factory that offers both wholesale solutions and fully customized services, you can consider Gentant. Our company has been dedicated to the manufacturing and global trade of Extended Female Thread Ball Valves for years, building deep expertise in this product. Gentant’s operations are supported by two key strengths: the scale of our manufacturing facility is large, ensuring significant production capacity and supply stability. Furthermore, our management systems are meticulous and refined, overseeing every stage from material procurement and precision machining to quality control and logistics. This combination of substantial infrastructure and detailed process management guarantees consistent product quality, on-time delivery, and the ability to meet specific customer requirements effectively.
The Extended Female Thread Ball Valve is a specialized variation designed for applications requiring easier access and operation in hard-to-reach or insulated pipelines. Its core function mirrors that of a standard ball valve: providing reliable, quarter-turn on/off control of fluid flow with minimal pressure drop. The defining feature is an extended stem assembly, which positions the operating handle farther from the valve body. This allows the actuator to protrude beyond pipe insulation, wall panels, or other obstructions, enabling safe and convenient manual operation without removing surrounding materials. The valve ends with internal (female) threads for direct connection to external threaded pipes, offering a secure and compact seal in plumbing, heating, and industrial systems.
Product Feature and Application
The Extended Female Thread Ball Valve is designed with an elongated body to facilitate easy installation in insulated piping systems or recessed wall spaces. This extension allows the handle to operate freely without interfering with thick insulation layers, commonly found in commercial HVAC and chilled water networks. Its primary feature is the deep internal threading, ensuring a high-torque, leak-proof connection that is ideal for heavy-duty residential plumbing and high-efficiency building projects.

Product Features & Advantages
GenTant Extended Female Thread Ball Valves are designed for rapid shut-off and reliable flow activation.
Premium Material: Constructed from HPb59-1 high-quality brass (National Standard).
Optimal Flow: Offers the lowest possible flow resistance (effectively zero).
High Performance: Capable of withstanding high pressure differentials during closure.
Rapid Operation: Select models feature opening/closing speeds of 0.05s to 0.1s, ideal for automated systems.
Compact Design: Lightweight and space-saving for easy integration into diverse piping networks.
Installation Guidelines
To ensure long-term performance and prevent structural damage, installation must be performed by qualified professionals.
Preparation: Ensure the piping system is clean. Remove protective caps and inspect ports for debris.
Alignment: Confirm that connecting pipes are perfectly aligned. Excessive misalignment creates installation stress that can damage the valve.
Correct Tooling: Use a wrench or pipe tongs with appropriate torque on the hexagonal or octagonal portion of the valve closest to the thread being tightened. Never apply force to the opposite end, as this may deform the body.
Thread Sealing: Use PTFE sealant on the pipe threads only. Follow ISO 228 standards for thread length; do not over-tighten, as "bottoming out" the thread can damage internal sealing surfaces.
System Support: Provide adequate support to prevent piping weight from stressing the valve.
Pre-Service Check: Verify pressure and temperature ratings match the system and cycle the valve fully (Open/Closed) once before commissioning.
Operating Instructions
Function: Extended Female Thread Ball Valves are intended for on/off service only. They must be kept fully open or fully closed and should not be used for throttling (flow regulation).
Mechanism: These are bidirectional valves. The handle position indicates the flow direction.
Water Hammer Prevention: Do not close the valve too abruptly to avoid "water hammer" effects (sudden pressure surges).
Handle Usage: Only use the factory-supplied handle. Never use extensions to increase leverage, as excessive torque will damage the internal components.
Inspection & Maintenance
General Care: Regular maintenance is typically unnecessary beyond occasional cycling and stem packing checks.
Filtration: It is highly recommended to install a filter at the system inlet to protect the valve's internal seal.
Leakage Control: If a stem leak occurs, tighten the packing nut clockwise by 1/4 turn. The PTFE packing is designed for compensation.
Safety Warning: Never attempt to repack or disassemble a valve while the system is pressurized. Always relieve pressure first.
No Disassembly: We do not recommend disassembling two-piece valves for part replacement, as this usually compromises the body/tailpiece integrity.
