Product information
The discharge valves produced by our company include flat bottomed discharge valves and pipe connected discharge valves. The valve seat is clamped with a discharge flange connected by bolts, making it easy to maintain the valve and replace the valve seat. The inner cavity of the valve body is designed as a streamlined channel with anti scarring and low flow resistance. It can achieve erosion resistance, corrosion resistance, and scar prevention under the working conditions of solid granular media.
