Multi Stage Multi Hole Pressure Reducing Unit for Liquids and Gasses MDP-L; MDP-G

restriction plate multi hole multi stage liquid

The EMCO Multi Hole/Multi Stage Pressure Reducing Unit for Liquid type MDP-L

The EMCO Multi Hole/Multi Stage Pressure Reducing Unit for Liquid type MDP-L are used to prevent critical/high pressure drops in continuous liquid flow pipe lines. By reducing the pressure in stages using multi hole plates the damaging cavitation is avoided. Multi hole plates can handle higher pressure drops than single hole plates. The multi stage design is based on the constant cavitation factor principle. Main applications are similar to the unit type SDP-L but is capable to handle differential pressures at lower noise levels.

The EMCO Multi Hole/Multi Stage Pressure Reducing Unit for Gasses type MDP-G

The EMCO Multi Hole/Multi Stage Pressure Reducing Unit for Gasses type MDP-G are used to reduce the pressure in a number of stages to a desired pressure and to secure as low noise development as possible. The gas passes each stage at sonic or critical velocity or at a lower velocity depending on the requirement. When the pressure is reduced the density of the gas or steam is also reduced. Higher velocity results in higher noise level. Therefore the design of the unit secures that the velocity through the stages of pressure reduction does not increase. In order to maintain a constant velocity, the cross sectional area is increased after each stage.
