Stainless Steel Pneumatic DN80 ISO Piston Type Tank Bottom Valve
Stainless Steel Pneumatic DN80 ISO Piston Type Tank Bottom Valve is an automated discharge valve mounted at the bottom of process tanks. It uses a pneumatic piston actuator to provide fast, stable opening and closing, ensuring efficient material release, high sealing reliability, and hygienic performance for industrial applications
Working Principles
The working principle of a Stainless Steel Pneumatic DN80 ISO Piston Type Tank Bottom Valve relies on compressed air to drive a piston mechanism that controls the opening and closing of the valve. When air pressure is applied to the actuator, the piston moves linearly, pushing the valve stem to lift the sealing plug away from the seat and allowing media to discharge from the tank bottom through the DN80 outlet. Reversing or releasing the air pressure causes the piston to return to its original position, pressing the plug firmly against the seat to achieve tight shut-off. This pneumatic operation enables quick response, consistent actuation force, and reliable performance under frequent cycling. The valve design supports hygienic processing, withstands cleaning procedures, and ensures stable flow control in automated systems
