Threaded Valve FAQ Section
Q: What types of fluids are Threaded Valves suitable for?
A: Threaded Valves are compatible with a wide range of fluids including water, oil, gas, steam, and many chemicals. The specific material (brass or stainless steel) should be selected based on the fluid characteristics. Stainless steel models offer superior corrosion resistance for aggressive media.
Q: How do I select the right size Threaded Valve for my application?
A: The valve size should match your pipe diameter. Common residential applications typically use 1/2" or 3/4" valves, while industrial systems may require larger sizes up to 4". Consider both the pipe size and flow requirements - our technical team can help calculate the optimal Cv (flow coefficient) for your specific needs.
Q: What maintenance does a Threaded Valve require?
A: Threaded Valves require minimal maintenance. We recommend periodic inspection for leaks, proper operation, and checking thread connections for tightness. For systems with particulates or scale-forming fluids, occasional cleaning may be necessary. Internal components may need lubrication every 3-5 years depending on usage frequency.
Installation Guidelines
- Clean all pipe threads before installation
- Apply appropriate thread sealant (Teflon tape or pipe dope)
- Hand-tighten first, then use wrenches for final tightening
- Align the valve handle for convenient operation
- Pressure test the system before putting into service

Threaded Valve FAQ Section
Q: Can Threaded Valves be used for high-temperature applications?
A: Our standard Threaded Valves can handle temperatures up to 400°F (204°C). For higher temperature applications up to 1000°F (538°C), we offer special high-temperature models with extended bonnets and high-performance packing materials.
Q: What's the difference between NPT and BSP threaded valves?
A: NPT (National Pipe Thread) is the North American standard with a 60° thread angle, while BSP (British Standard Pipe) has a 55° angle and is common in Europe and Asia. Our Threaded Valves are available in both standards - it's crucial to specify which threading you need when ordering.
Q: How long do Threaded Valves typically last?
A: With proper installation and maintenance, our Threaded Valves can last 20+ years in most applications. The actual lifespan depends on operating conditions, fluid characteristics, and maintenance practices. Stainless steel models generally outlast brass in corrosive environments.
Ordering Information
When ordering Threaded Valves, please specify:
- Valve size (NPT thread size)
- Material preference (brass or stainless steel)
- Pressure rating requirements
- Handle type (wheel or lever)
- Special requirements if any (high-temp, cryogenic, etc.)
Threaded Valve FAQ Section
Q: Are Threaded Valves suitable for potable water systems?
A: Yes, our brass Threaded Valves meet NSF/ANSI 61 standards for potable water applications. We use lead-free brass alloys that comply with all current drinking water regulations. Stainless steel models are also excellent for water systems.
Q: Can I install a Threaded Valve vertically?
A: Threaded Valves can be installed in any orientation - horizontal, vertical, or angled. For vertical installations with flow upward, ensure proper support for the valve body to prevent stress on the threads.
Q: What warranty comes with your Threaded Valves?
A: We offer a 5-year warranty against defects in materials and workmanship. The warranty covers replacement of defective valves but does not include labor for removal/installation or damage caused by improper use, installation, or maintenance.
Safety Considerations
- Never exceed the rated pressure/temperature limits
- Ensure proper system depressurization before maintenance
- Use appropriate personal protective equipment during installation
- Follow all local codes and regulations
