Multipurpose valve of axial flow with hermetic line electro drive and metallic seals

Application

Used in pipes, sealed with gas or fluid medium include toxic and highly explosive.

Features

• Opening and closing at maximum medium differential pressure without bypass pipes.
• Absolute sealing capacity with respect to environment.
• High two-sided gate sealing capacity within all pressure range.
• Sterility and purity of working medium.
• Availability of discharged ram-pilot valve which substantially reduces drive force.
• Emergency actuation in case of power supply loss.
• Simple maintenance due to availability of linear electric drive control unit, which determines the position of the shutoff - expansion device and provides data regarding its position.
• Option of engineering procedures automation.
• Valve body with rectifiable axial-symmetric orifice of low coefficient hydraulic resistance A packaged unit of small weight and dimensions in comparison with similar fittings.
• Enhanced reliability of metal welded bellows due to valve design.
• Engineering solution is covered by the patent.
