684 Pressure reducing valves made of gunmetal, with female threaded connections
All features and technical characteristics of the stainless steel versions also apply to the series 684 made of corrosion-resistant bronze. The fully vented valves that compensate variations in the inlet pressure are available with and without secondary venting, each in a membrane or piston version.
Pressure adjustment is tool-free via the ergonomically shaped handwheel. The extremely low pressure loss in the pressure adjustment area ensures that these powerful pressure reducing valves have almost no competition.
For the protection of:
- Commercial and industrial installations against excessive inlet pressure.
Use of pressure reducing valves when, despite varying pressures on the inlet side, a specific pressure on the outlet side must be maintained within a piping system.
Applications include:
- Compressed air supply installations
- Pneumatic control units
- Pressure boosting installations on the air side
- Shipbuilding industry and offshore installations
A pressure gauge for the set pressure is optional.
