Safety valve, preset and lead-sealed, G 3/4", DN 10, 4.00 bar, stainless steel 1.4571

Wherever a compressed air receiver or a pipe has to be protected against overpressure, this spring-loaded valve does the job without auxiliary power. It responds at 4.00 bar and discharges up to 199.8 m³/h. The connection is the G 3/4" thread in nominal size DN 10, and the body is made of stainless steel 1.4571.

Benefits

• Set pressure adjusted to 4.00 bar and sealed at the factory, no readjustment on site is required.
