Micro-Pressure Back-Pressure Regulators
Micro-Pressure Back-Pressure Regulators
Definition
Micro-Pressure Back-Pressure Regulator adopts rubber diaphragm pressure transmission,Micro-Pressure Back-Pressure Regulator is specifically designed for micro-pressure application requirements, and features stable output pressure. It is mainly applied to medium-flow gas systems and liquids (with structures suitable for liquids).
Design Features
Single-stage pressure reduction structure
Hard seal between the body and the diaphragm
Body thread: Inlet and outlet gas ports 1/2" NPT (F); pressure gauge and safety valve ports 1/4" NPT (F)
Built-in filter screen
Panel-mounted or wall-mounted installation available
