Electro hydraulic pneumatic control plug valve is a
kind of auto control valve, which can regulate the flow of solid granule. To
resist high temperature medium flushing, the head and seat of valve are lined
with anti-wear nonmetal. The valve is usually equipped at the bottom of
vertical pipe path to control the flow of fluid status solid granule. It is
widely used on the catalytic cracking unit in petroleum refinery or other
occasions with same demand.
