M4800A
FAIRCHILD - Volume Boosters
Model M4800A is a High Flow Pneumatic Volume Booster specifically designed for Valve and valve actuation systems. With its Cv of 9 in both forward and exhaust modes, this pilot operated booster provides fast response and accurate control for valve actuation.
Features
• An integral bypass valve, for optimum tuning and adjustment, even while in operation, to obtain maximum performance on opening and closing times with minimal overshoot or oscillation
• In its pilot operated regulator design, the M4800A handles up 250 psig, [17.0 BAR], (1700 kPa) supply pressure and delivers an output pressure up to 150 psig [10.0 BAR] (1000kPa)
• Cv = 9; Flow capacity of 500 SCFM (850 m3/HR) - fast response for quick valve opening and closing times
• Ratio accuracy of 0.5% - highly accurate valve control for your system
• Fixed deadband between the operation of the supply valve and exhaust valve provides accurate and stable final positioning of the valve
• Integral bypass needle valve optimizes response time and stability
• Soft seat supply and exhaust valves provide efficient leak free operation and prevents hunting, especially when used with modern electronic feed & bleed type valve positioners
• Pressure balanced supply valve maintains deadband specification preventing changes in control characteristics when supply pressure changes
• Damped diaphragm control chamber protects valves from damaging oscillation under high flow conditions
• Two accessory ports connected to the outlet chamber provide convenient access to the outlet for additional control accessories and pressure monitoring
• Tapped exhaust port allows for easy collection of exhaust air or use of a silencer
• In its pilot operated regulator design, the M4800A handles up 250 psig, [17.0 BAR], (1700 kPa) supply pressure and delivers an output pressure up to 150 psig [10.0 BAR] (1000kPa)
