The electric control valve we manufactured can be divided into three series, please select the suitable products you need
1. Direct-through Electric Control Valve
the diameter: DN20-DN350 generally suitable for the medium with little flow and high regulating accuracy
Single-seated control valve (simple structure, low cost, widely used, little differential pressure during work time)
Double-seated control valve (larger rated flow, applied to the larger differential pressure)
Model: common series ZAZP, imported series BELLAZP
Sleeves control valve (larger rated flow, applied to the largest differential pressure, better stability and anti- cavitations than the two models listed)
Model: ordinary series ZAZM, imported series BELLAZM
2 Series of Electric Control Butterfly Valve
The diameter: DN80-DN3000, usually applied to the larger flow controlling and lower differential pressure flows.
Simple-structure and low cost
Electric clamp-butterfly-valves for controlling(applied to mediums such as freshwater, sewage, seawater, steam, acid and alkali).
Flange control butterfly valves (applied to corrosive medium)
Electric three-eccentric centre and hard-seal control butterfly valves
(Applied to zero-leakage)
Electric air control butterfly valves （applied to atmosphere, coal gas ,etc with low cost）
3 Series of Electric Control Gate Valve
The gate valve is the common equipment in large-scale industrial air supply system.
The temperature of medium:
Round gate valve: DN100 or above
Square gate valve: specification and dimension are decided by the size of pipeline
Louver gate valve: specification and dimension are decided by the size of pipeline
