Replacement 7000BMVR Unitrol Gas Control Valve Natural Gas

Frequently Asked Questions

To help your customers feel confident in their purchase and reduce "item not as described" returns, here are the most common questions regarding this specific valve:

Q: Does this valve require electricity to operate? A: No. The 7000BMVR is a millivolt valve, meaning it is powered by the small amount of electricity generated by your system’s thermopile (standing pilot). This ensures your heater works even during a power outage.

Q: Can I use this valve for Propane (LP) instead of Natural Gas? A: This specific model is factory-configured for Natural Gas. While many Unitrol valves are convertible, you would need a specific LP conversion kit and a licensed technician to perform the change safely. We recommend buying the dedicated LP version if you are not using Natural Gas.

Q: How do I know if my old valve is a "7000 series"? A: Check the side of your existing valve body. Robertshaw/Unitrol valves usually have the series number (7000) stamped or labeled near the inlet port. If your valve has a large red dial and a millivolt terminal block (the black plastic piece with screws), this is likely the correct replacement.

Q: What is the difference between a 7000BMVR and a standard 7000BGO? A: The BMVR designation specifically indicates it is a Millivolt Valve with a Regulator. It is designed for higher capacity and precision compared to basic models, making it suitable for larger residential and commercial equipment.

Q: Is the pilot orifice included? A: This is the main gas control valve only. You should use your existing pilot tubing and orifice, or replace them separately if they are clogged or damaged.

Quick Troubleshooting Tip

Pro Tip: If your new valve isn't opening, check your thermopile first. A millivolt valve requires at least 250mV to 750mV from the pilot flame to engage the main burner. If your pilot stays lit but the main burner won't kick on, your thermopile may be weak!
