NEW! DM 618

Pressure Reducing Valve DM 618 – Mankenberg GmbH introduce the new Universal Valve for Standard Applications

Mankenberg further expand their position as one of the leading suppliers of self-acting control valves with the launch of the pressure reducing valve DM 618 and set a new standard for dimensions and equipment:


» Compact design (on average 20 % less than competition models)
» High regulating accuracy
» Body made of cast steel (GS-C 25)
» Medium-wetted internal parts made of stainless steel (1.4404 / SS316L)
» Closed spring cap made of stainless steel (1.4404/SS316L)
» Leakage line connection with adjusting screw seal
» Balanced cone
» Easy setting of nominal values



Compact Standard Cast Valve DM 618
single seat straight-way valve for high flow rates with balanced cone   |   suitable for liquids and gases up to 130° C   |   body of GS-C25 optionally CrNiMo steel   |    medium-wetted internal parts of CrNiMo steel / Duplex   |   very precise control |   spring cap with leakage line connection and adjusting screw seal
DN 15 - 100 PN 16 - 40  
    T 130°C
P2 0,8 - 10 bar Kvs 4,5 - 110 m³/h


The low overall height in combination with the cast steel body and the modular structure at a very attractive price make it particularly interesting for various application areas.


The new pressure reducing valve is available in nominal diameters from DN 15 through to DN 100. With a broad variety of elastomers, the soft seal version is suitable for different media such as water, glycol, oil, air, nitrogen, and natural gas.

The standard DM 618 is furnished with a body of cast steel (GS-C 25/A216WCB). The users receive a sturdy and low-maintenance control valve withstanding inlet pressures of up to 40 bar and featuring very favourable flow dynamics. The medium-wetted internal parts are made of corrosion-resistant stainless steel (1.4404 / SS316L). The closed stainless steel spring cap provides entire protection from accidental contact with the spring.Thus the valve meets the most demanding of customer requirements and compared to valves made of ductile iron it can withstand also higher pressures.


Thanks to its compact design, the valve’s installation height is significantly reduced and is approx. 20 percent below those of competitors without the flow rate being restricted. The non-rising adjusting screw ensures precise and easy adjustment of the set value. The proper function of the control valve can easily be determined during operation by touching the adjusting screw (easy to check).


Adjusted control surfaces and springs guarantee high regulating accuracy. The balancing piston keeps the valve virtually independent from the inlet pressure.


Thanks to modular construction, the valve’s pressure range can be adapted rapidly to changing requirements. The Mankenberg clamp system and a new and innovative plug-in unit ensure user-friendly maintenance. To modify the pressure range, the valve actuation can be easily changed any time.
