How to order
Select your NPT connection size above, then specify your required set pressure (any value from 25 to 300 PSI) in the order notes. The valve will be factory set and tested to that pressure before shipping. Larger ports offer higher relieving capacity — orifice sizes range from .295" (1/4") up to .578" (3/4" and 1").
Typical applications
Air compressors and air receiver tanks, compressed air piping and distribution, pressure vessels, pumps, and general industrial overpressure protection wherever a code-stamped relief valve is required.
The Kingston 118CSS hard seat brass safety relief valve combines ASME-certified protection, high flow capacity, and durable brass-and-stainless construction in 1/4" through 1" NPT sizes — a dependable overpressure safeguard for compressed air and industrial systems.
