Product Details

Electric multi-stage pressure reducing regulating valve Product Features

　MLILLERThe multi-stage pressure reducing electric control valve developed and produced by the company adopts a multi-stage cage sleeve valve core or an axial flow labyrinth valve core. The multi-stage pressure reducing valve completely controls the flow rate of the medium flowing through the valve, greatly reducing the noise generated by high-pressure gas or steam inside the valve. The stable multi-stage pressure reducing valve effectively prevents liquid from cavitation and is a stable control valve used in high-pressure medium environments.

Electric multi-stage pressure reducing regulating valve Design Features

◆ Continuous adjustment within high pressure differential range
◆ Adopting multi-stage throttling medium to gradually reduce pressure, with each stage pressure drop above the vaporization pressure, anti cavitation, and low noise.
◆ The valve core adopts a non-equilibrium structure, with conical sealing and good sealing effect.
◆ The sleeve structure is a porous cage type, arranged strictly according to the required adjustment characteristics, with good adjustment performance.
◆ The valve core is equipped with guidance on both the upper and lower sides to adjust balance, without vibration, and has strong self-cleaning ability.
◆ The sealing surface is welded with hard alloy, and the surface of the valve core (rod) is sprayed with hard alloy material, which is resistant to erosion and has a long service life.

Electric multi-stage pressure reducing regulating valve Application scenarios

◆ The boiler feedwater bypass is used for feedwater regulation during start-up or low load operation.
◆ Water supply recirculation bypass regulation (minimum flow control valve).
◆ High pressure bypass spray cooling, superheater spray cooling.
◆ Medium regulation in other high-pressure environments.
