FEATURES • High Performance: R6V valves are designed for a maximum pressure of 350 bar and a flow capacity up to 650 l/min. • Sensitive Control: The DENISON poppet design delivers the

RV5-10 - Relief Valve Spool, pilot operated 114 L/min (30 USgpm) • 350 bar (5000 psi) Operation When the inlet pressure exceeds the setting of the valve, the pilot section opens, causing a small flow across the orifice in the main spool. The subsequent pressure drop moves the spool against a light spring opening a ring of radial

Pressure Relief Valve V152: Limits pressure developed by the pump in hydraulic circuit, thus limiting the force imposed on other components. Valve opens whenever preset pressure is reached. Features: • 0,9 meter (3 ft.) return line hose kit • 3% repeatability • 55 - 690 bar (800 - 10,000 psi) adjustment range (1) ® Instruction Sheet V

The pressure relief valve must open at a predetermined set pressure, flow a rated capacity at a specified overpressure, and close when the system pressure has returned to a safe level. Pressure relief valves must be designed with materials compatible with many process fluids from simple air and water to the most

The SPV/SPVF pressure relief valve is a directly controlled slide valve for installation in pipelines and is used to safeguard low-pressure hydraulic 

5/5 · Pressure-relief valves are primarily used to protect hydraulic systems against overloading, which can lead to failure of the hydraulic system [ 2, 7, 8 ]. Almost all relief valves are settable. For lower flows (in general up to 10 L/min) a one-stage pressure-relief valve is used; higher flows require a two-stage pressure-relief valve.

The flow-pressure relationship is an important external characteristic of the pressure relief valve and the hydraulic circuit. So, many engineers have been
