AT Series Pneumatic Hard Seal Triple Eccentric Regulating Butterfly Valve Actuator Design and Features:
AT series pneumatic hard seal regulating butterfly valve is researched, developed and designed on the basis of comprehensive use of new technologies, new materials, new processes and innovative concepts at home and abroad, and has the following characteristics:
Full compliance with the latest international norms: ISO6211, DN3337 and VDWDE3845, NAMUR standards.
Extruded high-strength aluminum cylinder body, the inner surface is finely ground and hard anodized, with long service life, low friction coefficient and fast action.
Beautiful, compact, modern shape, multi-specification series of products make the selection more economical.
High-quality bearings are used for all movable surfaces. Low friction, long life, no noise.
Two independent stroke adjustment mechanisms are installed externally. When convenient, the 5° full open or full off position can be adjusted.
Actuators with the same external structure are available in double-acting and single-acting (spring return), and single-acting are normally closed and normally open.
The multi-function position indicator of the NAMUR standard visually indicates, installs and outputs all accessories.
Pre-compression load springs. Safe and easy to install and disassemble.
The piston and end cap are made of die-cast aluminum alloy, which has high strength and light weight.
Changing the seal material can be applied to high or low temperatures.
A variety of angular strokes (e.g. °, etc.) and three-position pneumatic actuators are available upon request. There is no need for a connecting plate, and the solenoid valve is installed directly.
