Control valve with pneumatic drive and actuator, control 4-20 mA shut-off, single-seat, two-way vertical control valve. RA is a linear pneumatic drive of the membrane type. The drive has two versions: DA - direct action, normally open (air pressure closes the valve) and RA - reverse action, normally closed (air pressure opens the valve). A wide range of applications allows this valve to be used with the most common process fluids, such as water, superheated water, steam, air, gases and other non-aggressive liquids.
