Our steel poles are made from quality sheet through bending,
forming, automatic welding and hot galvanization. We can reach one-run
machining length of 14m and can bend sheet of thickness up to 45mm. We
adopt advanced welding procedures, automatically weld main joints and
reach rank-II welding quality. We
have got 500kV Transmission Line Tubular Tower Quality Certificate from Power
Industry Steel Tower Qualified Inspection & Test Center from 2009
year.

Δ This valve is popularly used in automatic water supply system of water tanks, reservoirs and water towers in high-buildings, mining industry and factory. It functions to control the water level in water tank or reservoir.When the water level in reservoir rises to the preset level, the valve will close automatically; when water level declines bellow the preset level, the valve will open automatically for water compensation.
Δ Provided with soft-hard sealing plate, this valve uses the hydraulic control theory, closing force of valve plate is directly proportional to inlet water pressure, to achieve a dependable sealing effect. The semi-straight line fluid channel, wide valve body and flow area design all contribute to large flow and small flow resistance.
