Seven pressure-control valves will be discussed. These valves are: 1. Relief valves 2. Unloading valves 3. Sequence valves 4. Pressure-reducing valves 5. Counterbalance valves 6. Safety Valve Each of these valves works on the same principle; a spring force balances a hydraulic force.

Pressure Relief Valve (PRV) A closed valve is to limit the pressure in to prescribed maximum by diverting some or all output of pump to tank. The pressure can rise in a hydraulic system if: 1. The flow rate from the pump is larger than the flow rate through the actuator 2. The volume of a closed system is reduced.

Direct and pilot operated pressure control Eaton Hydraulic Screw-in Cartridge Valves (SiCV) E-VLSC-MC001-E6—January pilot operated types have.

The difference in construction between a single seated and double-seated valve are illustrated in Fig. 3. Referring Fig.1 (and also Fig. 3 (a)), only one plug is present in the control valve, so it is single seated valve. The advantage of this type of valve is that, it can be fully closed and flow variation from 0 to 100% can be achieved.

Control valves are devices that adjust the size of the flow path to manage and regulate fluid flow, pressure, temperature, or liquid level. Control valves are widely used to control or operate any process parameters in production wells, oil and gas facilities, chemical and petrochemical industries, refineries, and power plants.

A manifold valve is an essential component of pressure and differential pressure transducers. The main function of a manifold valve is to block or isolate the fluid flow to isolate process media from pressure instrumentation. The inclusion of a valve manifold in a tool helps it to be replaced or calibrated without requiring a shutdown.
