Stainless Steel Metal Seated Ball Valve

Size Range: DN15-DN200

Pressure: PN16

Body Materials: WCB/Stainless Steel

Introduction

Metal-seated ball valves incorporate a metal-to-metal seal between the seats and ball of the valve assembly. The metal seat ring contacts with the spherical surface, and the seat ring and the spherical surface form a seal due to the uniform spring load acting on the seat ring. 
The ball and valve seat are paired and ground, and all sealing areas of the entire sealing surface of the ball valve are precision ground. Suitable for high temperature and high pressure water, steam, oil, coal, fibers, thick and corrosive media, and media with particles.

Product Advantages
1. The valve body is a precision casting valve body, with secondary shot blasting treatment; Fine appearance and material conforms to standard
2. Valve trims are processed through CNC precision equipment to ensure accuracy
3. Blow-out proof stem
4. SS304 Ball Nitrided or Chrome Plated
5. The valve seat is sprayed with nickel alloy and the hardness of the sealing surface is reliable
6. Each valve body is subjected to surface pickling and passivation treatment, so that the surface of the casting has a uniform silver-white bright color, maintains metallic luster, and improves corrosion resistance.
7. Each valve is tested for shell and seal pressure in accordance with national standards before leaving our factory
