Description
When pressure at 1 rises above the spring bias pressure, the poppet is lifted and flow allowed from 1 to 2. The valve is closed (checked) from 2 to 1. Precision machining and hardening processes allow virtually leak-free performance in the checked condition.
Note: to obtain a good leak proof performance coin the cavity seat using a loose valve poppet (P/N 0F.S2.020) as a coining tool. Please consult factory for any question.
(*) Only external seals for 10 valves
