1. Product overview

 

 

The fully welded trunnion ball valve has a fully welded body which eliminates any possible leakage through body joints hence it is quite suitable for long-distance pipeline transport of oil & gas or low-emission required toxic media as well as buried/ underground service. Generally, Metals Valve’s fully welded ball valves are furnished with butt welding(BW) ends, either soft or metal seated. Flanged end connections RF or RTJ are available upon request. If the valve is used for underground service, extended stem and bonnet will be provided. In order to avoid the heat effect during installation/ welding, extended welding ends can be furnished and post weld heat treatment(PWHT) shall be carefully implemented. Serial Number: FWBV16. See the dimension & weight specifications of FWBV16.
