I. Overview Q611F three inner thread by pneumatic pneumatic valve actuators and three inner thread ball valve combination from, combined with the pneumatic valve actuators instead of the traditional manual operation, in large savings in human resources and time. Smart actuators can be controlled with electric valve positioner supporting 4-20mA input signal to control operation, to achieve accurate flow regulation. Pneumatic three-piece ball valve is a compressed air-driven, driven spool valve stem rotates 90 ° to achieve the effect of the flow regulator or open and close the valve body. Pneumatic three-valve using a wide range of open and close rapidly, simple structure, long service life. 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: the role of 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, signal feedback, air FRL, manual mechanism.
