Description: Control Valve, Daniel Series 500 are used where minimum pressure drop is required, or for applications where it is not practical to use the flowing stream as the power medium to operate a valve. As the main piston is controlled externally and there is a 45 degree body design, pressure drop through this valve is extremely low. Both compressed air and hydraulic fluid may be used to actuate the power cylinder. The Daniel Series 500 control valve is well suited for fire control, tank safety, remote on-off control, bypass control and with distribution systems. Features and benefits: fail safe on loss of power medium, modular construction - all internal parts including seat ring can be removed with the cylinder assembly without disturbing line connections, linear control characteristics, positive shut-off, bidirectional flow, 45 degree body design assures high capacity, extremely low pressure drop which conserves power consumption, atmospheric vent positively prevents mixing of line fluid & power cylinder operating fluid and available in 2 to 12-inch sizes.
