Pressure reducing valve with non-return function

Description:
The pressure reducing valve reduces a variable inlet pressure to a constant outlet pressure independent of varying flow conditions. The non-return function prevents any backflow as soon as the inlet pressure is lower than the outlet pressure.

Application:
- Pressure reduction when feeding into a system
- Emergency feeding into a second system

Infinitely adjustable outlet pressure from 1-15 bar
Minimum inlet pressure: 1 bar
Minimum pressure difference between inlet and outlet pressure: 1 bar

For rating, please specify the following:
- Flow (min., med., max.)
- Inlet pressure (P1 side)
- Outlet pressure (P2 side)

Components:
1: main valve
2: ball valve (A, B, C)
3: filter
4: orifice
5: throttle check valve
6: pilot valve
7: manometer with ball valve (A, B)
8: optical position indicator with vent plug (option: electric position indicator, opening limiter)
9: needle valve
10: check valve (A, B)
