Pilot valves LESER type 810, 820, etc.

Type 810
Pilot safety demolition valves of type 810 are not full-flow, this minimizes the flow of the medium in the control circuit, and with it emissions, in addition, prolongs the service life of the device. The setting pressure does not depend on the back pressure.

Type 820
The Type 820 bypass pilot safety valves manufactured by LESER open proportionally to the overpressure existing in the system, this reduces the loss of substance, reduces emissions and limits noise. The setting pressure does not depend on the back pressure. To ensure additional safety, the bypass servo controller can be purged with a discharge to the outlet of the main valve.
