Design & Feature:
The research and development design are base on principles of standardization,commonality interchangeability, modularization. Different diameter of valve has the maximum commonality in parts, easy maintenance and low using cost.
The same diameter of control valve can equipped with many kinds of structure forms of trims, can be combined to variety of valve type structure , such as single-seat valve, soft-seal single-seat valve, on-off type single-seat valve and cage single-seat valve, only by replacing part of the trims , in order to meet the requirements of variety of process operating..
Optimized design on the body fluid flow passage, to keep large flow capacity.
Packing part has various sealing structures, can be selected according to different operating condition parameter.A complete range of material , including normal and special material, such as Hastelloy,Monel, Ti and Ti alloy, Inconel alloy, Alloy 20 stainless steel, duplex stainless steel,etc.
Equipped with spring pneumatic diaphragm actuator, which has compact structure and can be changed the direct and reverse action at the user’s site.
Various types of hand-wheel such as top-mounted type, side-mounted type, hydraulic type and other type, can meet the requirements of the User.
Assembling intelligent valve Positioner and electro-pneumatic valve Positioner which are integrative and easy to verify . And other various types of valve
Positioners also can be selected.
According to the user’s requirements, equipped with the series 812 intelligent pneumatic actuator with the function of fault diagnosis , which have gained national invention patent.
