With better appearance, the valve is 80% lighter than the traditional dominant products like single valve, double-seat valve, 80% than sleeve valve, 45~55% lighter than Japan small regulating valve in the 80s.
Able to substitute numerous products that do not have complete functions resolving the problems like complex type selection and intense maintenance.
The controlling ratio can amount to 100 and the valves can keep excellent controlling ability from opening of 10%-90%.

Smooth operation and high reliability solves the amount filtering is fragmentary, resolving the great deadly structure faults of traditional valve divulgence.
Thoroughly free from the defects, metal sealing has big torgue, non-corrosion-resistant sealing surface.
Good pressure difference standing capability, anti-clog capability, simplest route, non-resistance regulating, highest KV value, Best self-cleaning performance.

Good regulating performance the regulating rate is approximate percentage.
Contrary to regulating valve, it is convenient and economical by suing electric power, omitting a series of expenses gas source station. Considering that the pneumatic regulating valve need positioning device the electric power regulating valve has exceedingly cost advantage.
High accuracy, decomposition degree attainability as high as 1/1000, low running cost, low maintenance cost.

Basic parameters-
Basic Error 2%, Reciprocating 1.5%, Dead Space 3%
