The performance of the electric single-seat pneumatic control valve

Metal seat leakage is less than the rated capacity of 0. 01%, in line with the ANSI B16. 104 - 1976 level iv; Soft seat leakage is less than 10 - rated capacity 7, in accordance with ANSI B16. 104 - 1976 level iv. Small pneumatic take locator to 1% of the whole trip, without a locator: a small 3% of the whole trip, LHA1 type small 5% of the whole trip) , match DKZ electric actuator is 1. 5%; With 361 l actuator is 2%; With the RS actuator is 1%; PSL actuator was 1%.
