VAG piston valve research and development principles and introduction

R & D principles and introduction of VAG piston valve Unlike the butterfly valve and gate valve, which are used only for pipeline cutting, the piston valve is a valve that can meet various special adjustment requirements. 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 different requirements, the replacement of export parts stainless steel piston is guided reliably sliding does 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. Application Diversion: The VAG piston valve can be used as a relief valve. It must be equipped with an annular venting device and can also be used as an explosion-proof pipe valve. Storage: VAGLH or E-type piston valve can be used as a liquid level or pressure regulator valve 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 drain valve or irrigation valve. Water Treatment / Sewage Treatment: The VAG E-type piston valve can be used as a pump start-up protection valve or with special regulating outlet components as well as a water treatment plant flow control valve. VAG E-type piston valve can also be used as a sewage treatment plant gas control valve. Water supply: Depending on the operating conditions, different outlet components are used as pressure / flow control valve, eg pipe network pressure balance.
