A valve that maintains constant system pressure. When the system pressure is exceeded by a predetermined amount, the valve opens and relieves the pressure, bypassing the fluid back to the system and thereby protecting the system against ruptures. The pressure at which the valve should open can be set. Bypass valves are commonly used in oil filters and oil coolers. Also known as a bypass relief valve.
