COVNA HK17 pneumatic piston angle seat valve main connection methods are: thread, flange, welding, clamp connection. The angle seat can save space by keeping the flow rate. It uses a single acting pneumatic actuator with spring safety protection to operate the guide angle seat valve. When using, it should be normally open or normally closed.
There are single acting and double acting. Single action (pneumatic head is usually a hole); working principle; according to the function of spring return to open and close, it is divided into normally open type and normally closed type.
Double acting (pneumatic head usually has two holes); working principle: air supply controls its switch. (according to the customer’s requirements, double action plus spring return can also be selected for more accurate control)
