At present, China can be divided into concrete pump S valve and gate valve, S valve mounted concrete pumps are closed systems, good sealing, high pressure conveying, pumping height high, but high requirements for materials, gate valve is an open system, feed easily, sealing relatively low, conveyor down, conveyor height is low, but low demand for materials.
Precast concrete plant valve products manufacturers very much, almost all manufacturers can do, Trinity and Vanda are two S valve system.
Due to market conditions, product manufacturers do little gate valve, gate valve pressure is small, no S-valve high pumping highly complex systems, the failure rate is high, so the market demand for small, only three one pump tiger Wuhan, Changsha Billiton Kosovo, the Alliance and several medium-sized manufacturers, the top sales market.
Changsha is the country's construction machinery precast concrete plant, innovative power strong, large-scale industrial cluster effect is obvious, the production of concrete pump sales in the country dominates.
