Expansion valves | Choosing the right valve
Water hammer is excessive pressure of the fluid, often occurring after a valve is closed quickly. It makes a distinctive noise you can hear in the pipes. This excessive pressure can create significant damage, which can go as far as causing the circuit to rupture. In order to avoid water hammer you can: install a pressure regulator before the valve to control the pressure. install a water hammer arrestor before the valve: a water hammer arrestor is a...
