Product Description

FREE-VALVE Pneumatic Wafer Type Ceramic Lined Control Regulating Butterfly Valves were operated in the harshest control environments and offers excellent resistant to cavitation which is major problem for process control valves. The ceramic materials are applied to the most common problem areas within disc of butterfly valve.These ceramic materials are 6-8 times harder than stainless steels and this ensures that the ceramic butterfly valve can operate under harsh, abrasive service environment.

Features
1.Wafer type ceramic butterfly valves are light and easy to install.
2.The disc sealing ring and seat are both high performance ceramics. High pure 99% Alumina, Zirconia and solid Tungsten carbide are used for wafer type ceramic butterfly valves. Different ceramics materials are suitable for different applications.
3.Body materials are selected on different applications.
4.Ceramics are nearly universally chemical resistant.
5.Much longer service life than any other common butterfly valves, and save maintenance cost for customers,due to high hardness and excellent corrosion resistance of high performance ceramics.
6.Pneumatic operation ceramic butterfly valves are easy to realize the remote control or the local control.
7.It has the inherent characteristic of the adjustable performance of butterfly valve.
8.Using single acting cylinder,it can be automatically turned off or turned on under air break conditions,Meeting process requirements on site.
