It is composed of a pneumatic membrane actuator and low flow resistance sleeve adjustment. It is a new generation of control valve products that conform to IEC standards. The actuator is a pneumatic diaphragm actuator. It adopts a multi-spring structure, small in size, and is lightweight: it can be widely used in industrial process control systems such as petrochemical, pharmaceutical, metallurgy, papermaking, water treatment, and other industries that require low noise and large pressure difference.
Technical data:
-DN: 25-500
-Pressure: PN16-100
ANSI Class 150-600
– Connection standard: GB, DIN, ANSI, JIS, etc. – Temperature: -20~550℃
– Flow characteristics: quick opening, linear, equal percentage – Leakage: 11 grades, V grades
Material:
-Body, Bonnet: Stainless Steel -Spool, Cage: Stainless Steel
Optional:
– Oil-free degreasing treatment
Features:
– The balanced valve core structure is adopted, the axial unbalanced force is small, the allowable pressure difference is large, and the stability is good.
– Large spool guide surface improves oscillations caused by eddy currents and shocks and reduces damage.
-The noise is reduced by about 10dB compared with ordinary single and double seat control valves. The valve has a simple structure and is easy to assemble, disassemble and maintain. -The valve body adopts precision casting valve body, S streamlined channel. The pressure drop loss is small and the flow capacity is large. Extended bonnet design, can be used for high temperature media.
-The valve body is designed according to the principle of fluid mechanics to have low flow resistance of equal section and large adjustable range.
