美国JOUCOMATIC气控阀的详细介绍

美国JOUCOMATIC气控阀
There are two exhaust flows in the exhaust mode (pilot and main). The pilot exhaust must be connected to the main exhaust when the air or inert gas cannot be exhausted to atmosphere.
For "Quick Exhaust" valves, pressure port is 1/20", exhaust port is 1/4".
IMPORTANT: A Minimum Operating Pressure Differential must be maintained between the pressure and exhaust ports. Supply and exhaust piping must be full area, unrestricted.
ASCO flow controls and other similar components must be installed in the cylinder lines only.
Diaphragm and main disc FKM only (pilot is low-temperature NBR).
Zero minimum when valve selection gasket is in external position and proper auxiliary air pressure is applied. Minimum 15 psi Operating Pressure Differential when selection gasket
is in the internal position.
Normally closed = 130 psi. Normally open = 105 psi.
• The solenoid valves do not require a minimum operating pressure
• Solenoid valves with explosionproof operator NA or NB type for use in potentially
explosive atmospheres according to ATEX Directive 94/9/EC
