Low Cost And High-precision And Automatic ZZV Micro Pressure Series Regulating Valve with Arbitrary Adjustment of Set Value From China
Product description
The ZZV series micro pressure regulating valve produced by our company does not require any external energy and is an energy-saving product that uses the energy of the regulated medium to achieve automatic regulation.
This series of regulating valves adopts a balanced single seat valve quick opening flow characteristic regulating mechanism, with no packing and frictionless movable components inside.
The medium pressure is stable, the regulating accuracy is high, and it is used for micro pressure control.
The sealing performance is safe and reliable, and the set value can be adjusted arbitrarily during operation.
Therefore, it is suitable for automatic micro pressure regulation of fuel gases, petroleum products in process, nitrogen or other protective gases in oil storage tanks, and heat treatment protective gases in various industrial furnace combustion systems.
