1) Only external seals for 10 valves
Description
When pressure at 2 rises above the spring bias pressure,
the poppet is pushed from its seat and flow is 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.
