pilot-operated pressure regulator (after-valve control) is composed
of the control valve, actuator and a pilot used for pressure
setting. It is suitable for controlling differential pressure in
the pipes of non-corrosive liquids, gases and vapors. When the
after-valve pressure rises, the control valve is closed. Parameters
of control valves: Trim features: 1、Built-in bellows provided with
pressure balanced structure and high sensitivity 2、Compact
structure, reliable performance, free of maintenance 3、The standard
modular design is adopted 4、Various combined controls can be
carried out through the assemblies Body type: straight-through type
Bonnet type: standard type heat dissipation type Flow
