Din Marine Pn16 Cast Iron Balancing Valve

DIN Marine PN16 Cast Iron Balancing Valve

Principle of balance valve: The principle of balance valve is counter-regulation in the valve body. When the pressure at the inlet increases, it automatically reduces the diameter and reduces the change in flow, and vice versa. If connected reversely, this adjustment system will not work. Moreover, the valve plate that plays a regulating role is directional, and reverse pressure can even reduce or even block the flow. Since the balance valve is installed for better heating, there is no problem of reverse installation. If it is installed backwards, it is a human error and will of course be corrected. Balance valves belong to the category of regulating valves. Its working principle is to adjust the flow rate by changing the gap (i.e. opening) between the valve core and the valve seat to change the flow resistance of the fluid flowing through the valve. The balance valve is equivalent to a throttling element whose local resistance can be changed. For incompressible fluids, it can be obtained from the flow equation.
