Note:1. ZZYN Double seat self-operated regulator take diaphragm type actuator for example. If the pressure of ZZYN Double seat self-operated regulator is 1000~3000KPa, please consult our customer service or sales people.

2.The table above is Pressure Subsection Range. Choose the median around for pressure control. The smaller the pressure range, the higher the precision . Therefore it should be used within the pressure setting range.
3. If the pressure ratio between before valve and after valve of ZZYN Double seat self-operated regulator with the pressure control after valve exceeds 10,it needs multi-stage decompression or two ZZYN Double seat self-operated regulator in series (can choose control valve with director except pressure before valve is below 0.8MPa)
4.It needs special design when the nominal pressure is over 6.3MPa.
5.This series ZZYN Double seat self-operated regulator’s lowest pressure control is 15 KPa.
