“When the pressure in channel B reaches the Daniel Reducing Control Valve setting, the valve opens, and the pressure in the system rises in tandem with it. Behind the main valve, oil is evacuated via the drain hole in channel B. Because of the drop in pressure across the main relief valve, orifice A opens, letting more oil into the tank and preventing the intake pressure from going much higher—the valves close again when the inflowing oil pressure drops below the valve setting.”
If you require a control valve for pumping, flow rate, mixing, or controlling a pipeline, Daniel has what you need. One basic valve may serve several functions since all Daniel 750 Pressure Reducing Control Valve are self-contained and actuated by an external pilot. Several user-friendly pilot setups allow you to choose or change the valve capabilities as required.
The unit-built structure and specific design components provide positively sealed, linearly acting valves, consistently fast responses, and leak-proof performance. Furthermore, the essential internals and body of the valves remain the same across the line, simplifying inventory management and reducing costs.
General control applications, including an external pilot for a range of control actions, are the intended purpose for every model in the 700 Series. These valves may be installed horizontally or vertically, and their flow direction is vertical.
Daniel's Advantages Of A Reduced Control Valve
Even sticky or filthy items may have their flow rate carefully controlled with a balanced piston and spring-biased arrangement.
Prevent shock pressure damage by controlling the closure speed.
Reduced pressure loss and maintenance compared to large-capacity axial flow valves operating at 45 degrees
Protect people and property with positive shutdown (ANSI Class VI) and fail-safe closure in case of power failure.
Saved Money On Running Costs By Not Using Nitrogen Gas
The valve may remain in the line since all its internal components are housed in a cartridge assembly, maximizing uptime.
Using A Simple Design May Save Maintenance Linked To Wear.
Daniel Reducing Control Valve are ubiquitous in hydraulic systems; these valves serve many purposes, including regulating fluid flow within a circuit and preventing the system's pressure from rising over a certain threshold.
Relief Valves
Most fluid power systems have a specific pressure range within which they are intended to be worn. The forces the system's actuators must generate to accomplish the job at hand define this range.
Without proper management or limitation of these pressures, pricey equipment and fluid power components are at risk of damage. Relief valves reduce the likelihood of this happening. When pressures go too high, these safeguards reroute excess oil, reducing the system's maximum pressure.
Relief Valves Operated By Pilots
Pilot-operated relief valves are the way to go when there's a minor pressure differential but a significant flow rate to release. A relief valve that a pilot controls has two stages of operation. A small, spring-biased relief valve—sometimes incorporated into the main relief valve—makes up the pilot stage, which controls the main relief valve. On the other hand, the pilot might be located at a remote location and linked to the main valve using a pipe or tube.
