TZY-10 Self-operated Pressure Regulating Valve
TZY-10 is a pressure-reducing regulating valve controlled by a pneumatic signal and used with an air regulator or program controller. The catalog describes diaphragm movement that adjusts valve opening from the input signal and output-pressure feedback.
Product features
The catalog identifies a 304 stainless-steel regulating valve. The pneumatic signal acts on the upper diaphragm chamber and output-medium feedback enters the lower chamber. Valve opening changes with diaphragm force to regulate output pressure. The catalog states compliance with HG/T3237-1989.
