Great Heater Control Valve!

Thanks to my knowledge gained in practice, I'm so pleased with this product. It`s a perfect fit, easy to install, works well, and comes at an affordable price .The only cons i can think OF is that it's made of plastic which may not last very long. However, considering the price of this valve, I'm still happy with my purchase..

Pros
  • Durable and long-lasting
Cons
  • Potential for leaks or malfunctions

Works like charm: Excellent Heater Valve

i purchased this heater valve for my automotive and it has exceeded my expectations .Based on my observations, the valve operates smoothly and doesn't have any leaks whatsoever. The installation process was easy and it fits perfectly with my car's system. It gives me full control over the temperature inside my vehicle. The only downside is that it was slightly more expensive than other options in the market, but the quality and performance make it worth the investment. Overall highly…

Pros
  • Durable construction and materials provide long-lasting performance.
Cons
  • Difficult to install without prior knowledge or experience.

Super sensitive to vacuum, 1 lb closes the valve.

Very vacuum sensitive, my 69 GS has about a pound of vacuum, when fully hot the valve closes shutting off all flow. Hot-to-cold flow to see if there's a design flaw in the valve or a problem with my on-car thermal regulator.

Pros
  • Automotive
Cons
  • unreliable
