AT Series

General & Features

    AT new rack-and-pinion pneumatic actuator is made by Wenzhou Mocheng Automatic Control Valve Co., Ltd., combined with the latest technology at home and abroad. By the innovative and optimized CAD three-dimensional design, it has beautiful and compact appearance and modern model; the application of new materials and processes enables more reliable quality and performance of the products; its more economical, with models with various specifications; the product is in complete consistence with the new international standard technical specifications,and thus can satisfy the current and future needs.

(1) The design of rack-and-pinion double-piston symmetrical structure enables fast and steady action, high precision, high output power as well as reverse rotation by simply changing the installation position of the piston.

(2) The extruded high-quality aluminum alloy cylinder, the processed inner bore by precision machining center, and hard anodized external surface of enable its longer service life and low friction coefficient.

(3) The integrated design enables all models of double-action actuators and single-action actuators have the same cylinder and end cap, which makes it convenient for changing action mode by assembling springs or dis-sembling springs.

(4) The combined preload safe spring assembly is safe and convenient for assembling car removing springs both in the installation process and on the operation site.

(5) The two separate adjusting screws on the external side, which are intended for the actuator installed on the valve, enable accurate and convenient adjustment of the OPEN or CLOSE position of the valve.

(6) The multi-functional position indicator is capable of on-site visual indication; besides its slot, consistent with VID/VIE3845 and NAMUR standards, enables installation and output all accessories, such as the limit     switch box, electric positioner and position sensor.

(7) The gas source interface, in line with NRMAR standard, is capable of direct installation of the NUMAR standard solenoid valve.

(8) The rack composite bushing and piston guide ring on the back of the rack as well as the bearing of the output shaft etc. Are intended for preventing metal-to-metal friction and increasing lubrication, to enable low friction and long service life.

(9) All fasteners are made of stainless steel, to enable long-term corrosion resistance.

(10) The connection part are in line with new intemational standards IS05211 and DlN3337(FO3-F25), to enable interchange and common use. 

Note: 1.The pneumatic and configuration of the valve with a soft sealing ball valves pressure for PN1.6MPA, soft sealing butterfly valve for PN1.0 MPA pressure

2. Such as the user to provide valve please according to the company the torque and

 provide for the valve by combining the actual torque accordingly.

3. The air cylinder to 0.5MPA above air pressure. If users with the valve thrust and

 air pressure, my company to new configuration of the cylinder.
