No, the TR wire on a Robertshaw 7956-336P gas valve does not connect to the positive connection. The TR wire typically connects to the thermostat to control the valve's operation. The positive connection is for the main power supply to the valve.

How do you connect copper propane pipe and shutoff valve?

To connect a copper propane pipe to a shutoff valve, you will need to use a threaded fitting that matches the size and type of the pipe and valve. Apply pipe dope or Teflon tape to the threads before connecting them. Tighten the fitting securely using a wrench or pliers to create a leak-proof connection.


How do you combine the Bunsen burner to the LP gas cylinder?

There will be a valve at the bottom of the Bunsen burner. Using a rubber tubing connect the valve to the regulator of the LPG cylinder.


Can a diaphragm valve be used for positive isolation?

Yes, a diaphragm valve can be used for positive isolation, as it provides a tight seal when closed, preventing the flow of fluid and ensuring that the upstream and downstream systems are effectively separated. The design of the diaphragm valve allows it to create a reliable barrier, making it suitable for applications requiring isolation. However, it's important to ensure that the valve is properly selected and maintained to achieve the desired level of isolation in specific applications.


What is the metal and rubber hose called on the side of a 350 motor called?

That component is called a "PCV valve," which stands for Positive Crankcase Ventilation valve. It helps regulate the flow of gases between the engine's crankcase and intake manifold for emissions control.


What are the valves that are strengthen by fibrous chords?

The valves that are strengthened by fibrous chords, known as chordae tendineae, are the atrioventricular (AV) valves: the tricuspid valve and the mitral valve. These fibrous cords connect the valve leaflets to the papillary muscles located in the ventricles, helping to prevent the valves from prolapsing during ventricular contraction. This structural support is essential for maintaining proper blood flow and preventing backflow in the heart.

Where does the PVC valve hose connect?

The PVC valve hose typically connects the positive crankcase ventilation (PCV) valve to the intake manifold or air intake system of an engine. This connection allows for the recirculation of gases from the crankcase back into the combustion chamber for more efficient combustion and reduced emissions. Properly routing this hose is essential for maintaining engine performance and preventing issues such as oil leaks or increased emissions.


How do I properly connect the dishwasher water connection?

To properly connect the dishwasher water connection, first ensure the water supply is turned off. Then, connect the water supply line to the dishwasher's water inlet valve using a compression fitting or hose clamp. Tighten the connection securely to prevent leaks. Finally, turn on the water supply and check for any leaks before running the dishwasher.

What type of valve is in a quick connect fitting?

A quick connect fitting typically contains a check valve or a ball valve. The check valve allows fluid to flow in one direction while preventing backflow, ensuring a secure connection. In some designs, a ball valve may be used to provide a manual or automatic shut-off feature when connecting or disconnecting the fitting. These valves facilitate easy and efficient fluid transfer while maintaining system integrity.
