PNEUMATIC VOLUME BOOSTER PISTON TYPE SERIES - RVBP-200 (1/2”) / RVBP-210 (3/4”) / RVBP-220 (1”) / RVBP-230 (1.1/2”) / RVBP-240 (2”)
DESCRIPTION
THE RTORK PNEUMATIC VOLUME BOOSTER IS ONE-TO-ONE SIGNAL TO OUTPUT SUPPLY AIR, WHEN USED WITH A POSITIONER AND ACTUATOR, IT IS A CONTROL DEVICE TO INCREASE THE STROKING SPEED OF CONTROL VALVES. WITH A FIXED MINIMUM INPUT VALUE IS DESIGNED TO SUBSTANTIALLY INCREASE ENOUGH VOLUME OF AIR TO QUICKLY AND FULLY STROKE OF LARGE ACTUATORS. ACTUATORS RETAIN THEIR NORMAL SLOW AND STABLE RESPONSES AS LONG AS THEIR SIGNAL FLUCTUATIONS REMAIN WITHIN THE DEADBAND LIMITS THAT CAN BE SET ON THE BOOSTER, WITH THE OPTION OF STANDARD VERSION AND CUSTOMIZATION OF CLIENT REQUIREMENT
FEATURES
VOLUME BOOSTER FUNCTION: AMPLIFIES A PILOT/CONTROL PRESSURE SIGNAL INTO A HIGH-FLOW PNEUMATIC OUTPUT, ENHANCING RESPONSE SPEED AND CAPABILITY FOR LARGE ACTUATORS AND CONTROL VALVES.
VERY HIGH FLOW CAPACITY: ONE OF THE LARGEST MODELS IN THE RVBP SERIES, DESIGNED FOR APPLICATIONS WITH VERY HIGH DEMAND FOR FLOW AND RAPID ACTUATION.
WORKING PRESSURE: TYPICALLY SUPPORTS INLET PRESSURES UP TO ~20 BAR (MODEL DEPENDENT) WITH ROBUST DOWNSTREAM PERFORMANCE
CAPTIVE EXHAUST VENT: BUILT-IN EXHAUST VENTING ELIMINATES THE NEED FOR SEPARATE EXTERNAL VENT PIPING
INDEPENDENT FILL AND VENT CONTROL: ALLOWS CONTROLLED FLOW INTO AND OUT OF ACTUATORS OR VALVE PILOT LINES FOR FAST ACTUATION AND SAFE VENTING
LARGE PORT SIZES: USUALLY 1″ OR LARGER PROCESS CONNECTIONS TO ACCOMMODATE HIGH FLOW VOLUMES
SEAL MATERIAL OPTIONS: AVAILABLE IN VARIOUS ELASTOMER SELECTIONS (VITON) FOR BROAD TEMPERATURE RANGE AND MEDIA COMPATIBILITY
MEDIA COMPATIBILITY: COMPRESSED AIR AND COMPATIBLE INERT GASES
TYPICAL USE CASES: BOOSTING PILOT PRESSURE FOR LARGE PNEUMATIC ACTUATORS / RAPID ACTUATION OF LARGE ESD (EMERGENCY SHUT-DOWN) VALVES OR CONTROL VALVES / HIGH-CAPACITY PNEUMATIC CONTROL SYSTEMS REQUIRING LARGE FLOW BOOSTS.
ROBUST INDUSTRIAL DESIGN: BUILT FOR FREQUENT CYCLING, HEAVY-DUTY DUTY, AND LONG SERVICE LIFE IN INDUSTRIAL ENVIRONMENTS
