GENERAL FEATURES

A series is a piston actuator made of aluminum alloy die-casting,  maintenance-free, and is sturdy and durable；

The Spindle is secured by a V-shaped packing gland, which has low maintenance and self-adjusting characteristics, ensuring that the spindle still maintains reliable sealing after long periods of reciprocating motion. Additionally, the guide sleeve installed in front of the sealing packing functions as a scraper ring, protecting other seals from contamination and damage.

Characteristics:

*  The connection between the valve seat and the valve spindle adopts a floating design structure, which ensures the sealing of the valve disc and the valve port.；
*  A series actuators are suitable for high pressure and high temperature operating environments.；
*  Wide range of piston-type operators ( 40- 50 - 63 - 80 mm dia.) rotatable through 360°, for maximum performance at different minimum pilot pressures ;
*  Anti-waterhammer design (fluid entry under the disc)

Advantages:

*  A series actuators can be used with a variety of fluid valves.；
*  Valve ends: Female thread, Male thread,Butt welds, Socket welds, Flange ends, and Tri-clamp ends.
*  Y  type design, high flow rate；
*  NC. and NO. universal actuators with modular universal accessary program up to control head;
*  Special connection ends and body materials are also available。
