Restricting orifice plates enable to reduce pressure of medium in the orifice plate outlet (under constant flow) to required level, i.e. these function as hydraulic resistor. If these are used in cascades, they gradually decrease medium pressure and prevent it from cavitation.

Use: For all types of fluids ranging from PN6 to PN250

Multiple restricting orifice plates placed in sequences (up to 5 throttling orifice plates) are sometimes used for minimization of vibrations or cavitations in applications with high loss in pressure, when it is suitable to decrease pressure of medium gradually. Critical loss in pressure can limit loss in pressure through orifice plate. Calculation of multiple restricting orifice plates are realised by our own authorised software.

Use: For all types of fluids ranging from PN6 to PN250
