Model name
A13P to A50P-2 – High performance type
Features
– These types of pressure equalizing valves have the same capacity (in-house comparison) as the one-class higher model in diameter.
– Has a wide range of flow rate (up to 1/100 under the optimum condition) and maintains an accurate air-fuel ratio with good control to the small-flow-rate zone.
– Efficient and energy saving combustion can be achieved by introducing this pressure equalizing valve.
