Angle-Seated Externally Operated Valve is an externally operated angle seat valve. It is designed for use in robust industrial applications. The valve operates at very high medium temperatures and viscosities, and is insensitive to dirt particles in the medium. Hence it is also called trouble-shooter valve. This valve has angle-seated piston and bronze or stainless steel valve body. It is well designed to give the best flow capacity & the closing cone is totally lifted away from the stream when the valve is opened, giving no restriction to the flow
