Pressure reducing valve DM 505

Mankenberg GmbH

All stainless steel construction
Non-rising adjusting screw
Quick-release body profile clamp
Sense line connection (for outlet pressures ≤ 1,1 bar)
Soft-sealing valve cone.
High corrosion resistance.

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 pressure reducing valve DM 505 is a diaphragm-controlled springloaded proportional control valve for small volumes. This pressure reducer is manufactured from deep-drawn stainless steel featuring excellent corrosion resistance. The tubular inlet spigot of the valve body accommodates the seat aperture. The soft-sealing valve cone is guided in the seat assembly and connected with the control diaphragm by means of a stirrup which surrounds the seat assembly.

Use Cases

Typically used in small-flow industrial liquid, gas, and steam pressure regulation applications.

Capabilities

Reduces inlet pressures up to 250 bar to controlled outlet pressures between 0.005 and 20 bar, depending on spring setting.
Operates self-acting, without external power.
Suitable for liquids, gases, and steam up to 130 °C.
Allows easy maintenance and spring/diaphragm replacement without special tools.
Configurable with optional sealed spring cap and leakage line for hazardous media.
