R & D concept and only for pipeline cut off the valve and gate valve is different from the piston valve is to meet the special requirements of a variety of valves. The adjustment function is based on a piston-like cylinder in the valve cavity for axial movement to achieve. Product Features Design Features: Adapt to the fluid conditioning requirements of different occasions in the factory; Best anti-cavitation characteristics; High flow capacity; Long service life of sealing system; Double sealing of metal and elastic material; Closely closed; Pressure balanced drive; Small operating force? Depending on the operating conditions of the different requirements, the replacement of export parts? Stainless steel piston is guided reliably sliding? Will not produce tilt or run sluggish? Can be installed in any position. How it works: Flow from the axial arc into the shell, regardless of the location of the piston, the valve cavity regardless of any location of the flow cross-section are ring-shaped, at the exit axis contraction, in order to avoid possible cavitation due to throttling Body and pipeline damage, while regulating the linearity of its standard size: DN150 to DN1200. Features: The control valve used in the fluid; under the open conditions of circulation cross-section for the ring; linear adjustment; integration of the valve body; according to different working conditions to take different control parts; outlet parts by the longitudinal movement of the crank drive mechanism control; Standard gearbox with position indicator; flange standard according to EN1092, PN10 / 16; body length according to EN558-1, basic sequence 15 (DIN3202, F4) standard. Applications 1, water diversion: VAG piston valve can be used as a relief valve, to be equipped with annular venting device can also be used as explosion-proof pipe valve. 2, storage: VAGLH or E-type piston valve can be used as a liquid level or pressure control valve 3, water: VAGLH-type or S-type piston valve can be used as a flow control valve, E or LH type can be used as a net Valve or filling valve. 4, water treatment / sewage treatment: VAG E-type piston valve can be used as a pump start protection valve, or with a special regulation of the export components can also be used water treatment plant flow control valve. VAG E-type piston valve can also be used as a sewage treatment plant gas control valve. 5, water supply: According to the conditions of the use of different export parts, as a pressure / flow control valve, such as pipe network pressure balance. Applications where pressure changes need to be on the export flow or pressure requirements of the occasion Media: all kinds of fluids
