RTZ-25/0.4AQ Series Direct-Acting Gas Pressure Regulator

DATE:2014-01-14 | comments: | posted by:liuailin

RTZ-25/0.4AQ series gas pressure regulator is designed for regulating high pressure and medium pressure of city piping. It apply to residential and industry users, preferably use in the situation of sudden changes in capacity or where gas shut-off is solenoid-controlled.

Products Features

1. Built-in balance diaphragm, prompt response.
2. Valve port diameter is same to inlet diameter, 100% flow passed.
3. BYO overpressure automatic shut-off valve, small in size.
4. Inlet and outlet connect with pipeline directly, easy to install.
5. Pneumatic cut-off, manual rest, safety for use.
