Pneumatic actuators - Import export

Proval A210 Series innovative, compact design pneumatic rack and pinion rotary actuators including all critical components are manufactured in-house using dedicated state-of-the-art CNC machines following ISO quality assurance standards. Proval pneumatic actuators that can be set either to fail-open or fail-close, comes in 18 different sizes in both double and single acting types. This Series of actuators having torque figures in ranges 9 to 9767 Nm are well suited to operate part-turn valves such as plug ,ball and butterfly valves.

Exhaust gas bypass systems are made as additional equipment in exhaust gas heat exchangers. 3-way flap is required for bypass systems. By-passing the gas flow makes it possible to adjust temperature inside boiler (exhaust gas heat exchanger). Before delivery, we do a thorough test drive for every single damper, using actuator and special measurement equipment, to make sure that they function as expected and are ready to serve reliably on site. Availaible in steel, stainless steel or heat resistant materials Flange type and size depending on customer needs We develop dampers in different sizes and various temperature ranges Actuator options; Pneumatic actuator, Electrical actuator
