Balanced piston relief valve is designed for use in applications requiring an adjustable regulating valve to limit the pressure in a hydraulic circuit to a predetermined maximum. The relief valve consists of a control poppet and main spool which provides low pressure differential and quiet operation. Pressure can be adjusted by loosening a jam nut and turning the adjustment knob. A vent port is provided. These valves are: high flow, gauge port standard, quiet operation / no chatter, optional vent and remote and port connection.
Suitable for pressures up to 3000 psi, flow controls are available with (bypass type)or without (resistor type) integral relief valves. These non compensated adjustable flow control valves are suited for applications requiring flow regulation without pressure compensation.
