Valves in the legs are essential for maintaining proper blood circulation. They prevent the backflow of blood as it travels from the lower extremities back to the heart, ensuring that blood flows in one direction. This is particularly important against the force of gravity, helping to prevent conditions like varicose veins and promoting overall cardiovascular health. Without these valves, blood could pool in the legs, leading to swelling and other complications.

Do all new domestic radiators need a thermostat valve?
No
Do gas water heaters need to be on a pedestal?
No, they don't. Those that need air entry underneath come with short legs fitted.
How do you size a boiler relief valve?
The relief valve should be at least as large (in BTU/hr capacity) as the input of the boiler. A 3.5 million input boiler would need then a relief valve to handle at a minimum 3.5 million BTU/hr.
Why are direct acting relief valves not used on high pressure and high flow hydraulic systems?
As a direct relief valve opens, its spool or poppet pushes against a spring. As the spring compresses, the system pressure necessarily rises due to the spring constant. To handle large flows, you need a big valve. To minimize the pressure rise due to the spring constant you need a long spring. To minimize the pressure drop due to the valve body, you need a big valve body, which in turn needs a bigger spring. As the operating pressure goes up, you need stiffer (typically bigger)springs. Eventually the cost of the valve is prohibitive and a pilot operated valve is called for. There are benefits to using direct operated valves which may out weigh the costs, but most direct operated valves are limited to medium and low pressure settings.
Where do you install a pressure equalizing valve?
Need more info - what is it for? What is the size of the pipe and the pressure differences you are trying to get?
Do you need a special pump for a Presta valve?
Yes, you typically need a pump with a Presta valve adapter to inflate a tire with a Presta valve.
How important is the legs?
A lot, you need you legs for almost everything.
How many dogs do you need to have 100 legs?

Why do polar bears have such fat legs?
because they need warmth to survive and fat on their legs keeps their legs warm
Why do people have two legs?
because we are human not animals
Does oil on the side of the valve cover indicate a need for major repair?
no, but it does mean you need to replace the valve cover gasket.
How do you remove valve springs?
you need to compress the spring with a valve spring compressor tool, and then remove the valve keepers, and retainer.
