1900
Series
The Consolidated® Type 1900 safety relief valves
are designed to be highly adaptable in order to meet numerous
application requirements. The Consolidated Type 1900 safety
relief valve provides reliable overpressure protection for
critical equipment. The unique "eductor"
tube design reduces pressure in the bonnet, which minimizes
chatter and ensures that ASME certified relieving capacity is
available. Some additional options that make this product
line the most versatile SRV in the industry, includes liquid,
vapor, and steam trims, bellows construction, NACE trim, and
corrosion resistant materials.
