Mankenberg GmbH

Self-acting pressure reducing valve for high pressures.
Diaphragm-, piston-, or bellows-controlled spring-loaded design.
Multiple seat designs per size.
Soft or metallic valve cone sealing options.
Pressure gauge connection (optional).
Hard-faced valve cone and seat (optional).
Leakage classes III or V, optional IV, per DIN EN 60534-4 / ANSI FCI 70-2.

Self-acting pressure reducers are simple control valves offering accurate control while being easy to install and maintain. They control the pressure downstream of the valve without requiring pneumatic or electrical control elements. The DM 510 and DM 514 pressure reducing valves are diaphragm, piston or bellows-controlled spring-loaded proportional control valves for high inlet and outlet pressures. They can be supplied with three types of connections: sockets, flanges and welding spigots. Each size of valve may be fitted with three different seats. The valve cone may be fitted with a soft or metallic seal.

Use Cases

Typically used in high-pressure industrial fluid and gas control applications.

Capabilities

Reduces inlet pressures up to 320 bar to controlled outlet pressures up to 160 bar, depending on model and setting range.
Operates without external power or control systems.
Suitable for liquids, gases, and steam up to 400 °C (depending on materials).
Configurable with different control principles (diaphragm, piston, bellows).
Supports multiple connection standards and custom materials for demanding media.
