One , D671X Wafer pneumatic valve , pneumatic control valve :
D671X soft sealing pneumatic valve is composed of cast iron, carbon steel or stainless steel valve body , the valve plate , stem and rubber seals , pneumatic actuators, pneumatic components. For temperature ≤ 120 ℃ , such as food , pharmaceutical, chemical, petroleum , power, textile, paper , etc. to the drainage pipe for regulating the flow of gas and the closure of media effects process automation .
Note: In the absence of instructions , the factory default " pneumatic valve " means switching without locators for pipeline medium closure ( ie, only the fully open or fully closed ) ; " pneumatic control valve " is the band positioning modulating flow control , regulate or closure for pipe flow media ( ie valve plate can be positioned midway )
Two , D671X pneumatic control valve features:
1, D671X Wafer butterfly valve pneumatic double eccentric structure , sealing number, the more and more tightly .
2, the valve can be installed using the rubber seals on the different characteristics of the media according to customer needs.
3, due to the disc using frame structure, the flow resistance of the medium is small, a large area of ??mobility.
4 , the overall paint , can effectively prevent corrosion and replace the seal as long as the seat seal material can be used in different media .
5, D671X pneumatic butterfly clip on the unique technology used to make the valve easier to install , simple manipulation , looks good .
Third, the pneumatic control valve configuration options , pneumatic valve pneumatic actuators and pneumatic components :
The following optional accessories according to the different controls and requirements:
Truncated accessories: single solenoid valve , double solenoid valves , limit switches back to the hearing .
Modulating accessories : Electrical locator, pneumatic positioners, electrical converters .
Gas processing accessories: air filter regulator , air FRL .
Manual mechanism : HVSD handheld agencies
Cylinder type : single cylinder or twin cylinder Working pressure : 0.4 ~ 0.7MPa cylinder switch time: double -acting 1 to 5 seconds
Cylinder air consumption : 1 ~ 131L solenoid valve power supply : 220VAC, 24VDC
