I. Overview Q611F three inner thread pneumatic valve by the pneumatic actuator and three inner thread ball valve combination from, combined with the pneumatic valve actuators replace the traditional manual operation, in large savings in human resources and time. Smart actuators can be controlled with the electric valve positioner supporting 4-20mA input signal to control operation to achieve precise regulation of flow. Pneumatic three-valve is powered by compressed air, the stem drive spool is rotated 90 ° to achieve flow adjustment or closing action of the valve body. Pneumatic three-valve using a wide range, opening and closing fast, simple structure, long life, especially suitable for medium viscous, containing particles, fiber properties and other conditions. Second, the product features nominal pressure: 1.6-6.4MPa nominal diameter: DN10-100mm, 1/4 '' - 4 '' Main material: 304,316,316L stainless steel; Temperature range: -20 ~ 185 ℃ Suitable medium: water oil, gas and some corrosive fluid (WOG). Third, the pneumatic actuator parameters: Role Type: double-acting piston, spring return; air pressure: double action: 2-8bar, single action: 4-8bar; operating range: 0 ~ 90 ° ± 5 °; Locator Signal: 4 ~ 20mA; Pneumatic Accessories: solenoid valves, positioners, feedback signal, air FRL, manual mechanism.
