Insert type
Check, poppet type
When pressure at 2 rises above the spring bias pressure, the poppet
is lifted and flow allowed from 2 to 1. The valve is closed (checked)
from 1 to 2. Precision machining and hardening processes allow
virtually leak-free performance in the checked condition.
Note: UNF and Metric versions available on request. Consult factory.
