Ball Valve pneum. direct
Series A0723-28/0804 - CRYO
Valve A0728/0804/8TT2-7F
Ball valve made of stainless steel. Automated with pneumatic actuator, single-acting: The valve is closed by spring force in the rest position. If voltage is applied to the pilot valve type 81 mounted on the actuator, the ball valve opens with the aid of compressed air. The ball valve closes by spring force when the pilot valve is de-energized. Alternatively: Pneumatic double-acting actuator or with hand lever. Valve suitable for LN2 - LOx, cleaned and degreased.
