628 Pressure relief valves made of gunmetal, angle-type, with threaded connections
A proven all-round valve with proportional operating characteristics and an extremely compact design. In addition to the basic version, these valves are also available for a wide range of customer requirements, such as a gas-tight version or with a lifting lever.
With various available sealing materials, this valve is suitable for a wide range of media and temperatures.
As a closed, gas-tight version without a lifting mechanism suitable for all media.
This makes this series an economically interesting alternative for plants that do not require approval or do not fall under the PED. Furthermore, due to its relatively large adjustment range per spring, it is particularly suitable in cases where either a stock valve for various applications and set pressures is required, or when the customer is looking for an adjustable pressure relief valve.
For the protection of:
- Pressure tanks/systems for neutral/non-neutral vapors, gases, and liquids
- Steam boilers and steam installations
If proportional opening characteristics and only small venting volumes are required (i.e., protection against expansion due to heating), please observe the installation-specific regulations and use a suitable valve design and sealing material.
Applications in:
- Temperature regulation technology
- Cooling systems, industrial cooling
- Test setup construction
- Process equipment construction
- Shipbuilding industry and equipment of sea vessels
- Machinery construction
