Female Thread Ball Valve
GenTant is a leading manufacturer and supplier of Female Thread Ball Valves in China, with a dedicated focus on continuous product technology development to enhance performance and durability. The valves we produce have an exceptionally wide range of applications. They are fundamental components in numerous residential, commercial, and light industrial systems, commonly found in plumbing and water supply networks, HVAC equipment, gas lines, irrigation systems, and various process instrumentation setups. This broad applicability underscores the valve's essential role in ensuring safe, reliable, and efficient fluid control across diverse industries and infrastructure projects worldwide.
A Female Thread Ball Valve is a highly versatile and efficient quarter-turn shut-off device designed for reliable on/off control in a wide array of fluid systems. Its primary function is to start or stop flow by rotating a hollow, perforated ball 90 degrees within the valve body. In the open position, the bore aligns with the pipeline for full, unobstructed flow with minimal pressure drop; when closed, the solid side of the ball blocks the flow path completely. Featuring internal (female) threads at its ports, it is designed to connect directly to external (male) threaded pipes or fittings, offering a compact, robust, and leak-resistant seal ideal for applications requiring frequent operation.
Product Feature and Application
Female Thread Ball Valves feature internal threading at both ends, allowing for a secure, direct connection to male-threaded pipes without extra fittings. Their compact, quarter-turn design ensures quick shut-off and reliable, leak-proof performance. In residential and commercial sectors, they are essential for potable water lines, HVAC systems, and gas plumbing. Their ease of installation makes them a top choice for contractors and maintenance repairs.

Product Features & Advantages
GenTant 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: 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.
