Pressure Reducing Valve DM 618Z –
Compact Universal Valve for Steam Applications

Following the successful introduction of the pressure reducing valve DM618 with soft seal for liquids and gases a few months ago, the metallic seal version for steam applications DM618Z is available as of now and also sets a new standard for layout and functionalities:


» No compensation vessel required, easy assembly
» High regulating accuracy
» Body made of cast steel (GS-C 25)
» Medium-wetted internal parts made of stainless steel (1.4404)
» Closed spring cap made of stainless steel (1.4404)
» Leakage line connection with adjusting screw seal
» Balanced cone
» Easy setting of nominal values



Compact Standard Cast Valve for Steam Applications DM 618Z
single-seat straight-way valve for high flow rates with balanced cone | usable for liquids and gases up to 130 °C | body made of GS-C25, optionally stainless steel | medium wetted internal parts made of stainless steel 316L | very precise regulation | spring cap with leakage line connection and adjusting screw seal
DN 15 - 100 PN 16 - 40  
    T 250°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 the DM618Z particularly interesting for various application areas.


The new pressure reducing valve is available in nominal diameters from DN 15 through to DN 100.


The standard DM 618Z 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 30 bar at 250°C and featuring very favourable flow dynamics. The medium-wetted internal parts are made of corrosion-resistant stainless steel (1.4404 / SS316L). In addition, 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 the non-rising adjusting screw a precise and easy adjustment of the set value is ensured. The proper function of the valve can be determined with ease during operation by touching the adjusting screw (Mankenberg easy check).


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


Thanks to the modular construction, the valve’s pressure ranges can be quickly adjusted to changing conditions. 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.
