The Model BTV-30 Van Stone Flanged Thermowell is precision-machined from solid bar stock to provide superior strength and reliability in demanding process environments. Designed with a Van Stone (lap joint) flange connection, this model allows for flexible alignment during installation while maintaining a secure, gasket-sealed fit. The thermowell is compatible with standard lap joint flanges (ANSI, DIN, or JIS), making it ideal for systems requiring easy maintenance or frequent disassembly.
Built to withstand high pressures and temperatures up to 600°C, the BTV-30 is available in straight, stepped, or tapered stem designs, with custom immersion lengths to suit specific applications. Commonly used in the chemical, petrochemical, and power industries, it is offered in a range of corrosion-resistant materials such as SS316, Monel, or Hastelloy. Optional accessories and testing (hydrostatic, PMI, or radiographic) are available upon request to meet stringent project requirements.
Customers consistently praise our temperature and pressure gauges for their accuracy, durability, and ease of installation. From HVAC professionals to industrial users, many highlight the clear readings and reliable performance under tough conditions. Whether for home systems or heavy-duty applications, our gauges are trusted for getting the job done right.
A temperature and pressure (T&P) gauge is used to monitor both the temperature and pressure levels within systems like boilers, water heaters, HVAC units, and other pressurized equipment. It helps ensure the system is operating safely and efficiently.
Installation typically involves threading the gauge into a designated port on the system (usually a 1/4" or 1/2" NPT fitting). Always ensure the system is depressurized before installation and use thread sealant to prevent leaks. Refer to the product manual for specific instructions.
For best performance, it’s recommended to check calibration annually, especially in industrial or high-usage environments. Replace the gauge if you notice inaccurate readings, a stuck needle, or visible damage to the dial or housing.
This pressure gauge is spot-on accurate and durable. I installed it on a boiler system for a commercial client, and it’s been holding up perfectly under high pressure and heat. The stainless steel casing is rugged, and the glycerin fill really helps reduce needle vibration. Definitely a professional-grade product worth the price
Very reliable temperature readings and the digital display is easy to read even in low light. I use it for monitoring HVAC systems and it has made diagnostics much quicker. The only downside is that the battery compartment is a bit tricky to open, but overall, it’s a solid product.
I’ve been using this temperature and pressure gauge for a few months on my residential boiler system, and it’s performed consistently well. The readings are accurate, and the dual-scale display is easy to interpret. It was easy to install and fit perfectly into the existing port. Build quality feels solid with a brass connection and clear lens. So far, it's been reliable under both high-temp and high-pressure conditions. I’ll be purchasing more for future installs.
