Model 43xx

Designed to protect your pressure system or instrument, the 40xx are an essential accessory to prevent overpressure anddropout situations. Once the supply pressure exceeds the set value, the pressure limiting valve closes and isolates the instrument from the main pressure source. If the pressure drops below the set value, the pressure limiting valve will automatically reopen.
