Hydraulic relief valves are used to limit the pressure in a hydraulic system. They achieve this result by allowing the pressurized hydraulic fluid to flow out of the system into an auxiliary passage.

In hydraulic control systems, the relief valve acts as a check valve, with a ball and an adjustable spring. When a relief valve opens to divert fluid into an auxiliary passage, the pressure inside the hydraulic cylinder drops and allows the valve to close. A hydraulic system will often employ several types of valves, although the hydraulic relief valve is usually the first encountered in the circuit. Hydraulic relief valves can be found in almost any mechanism that runs on hydraulic power, such as automobile transmissions, brakes, power steering, aviation and in industrial and construction machinery.

Relief valves are built from the same basic materials that most hydraulic valves are made from. The strong and corrosion resistant metals that are most common are stainless steel, aluminum, iron, brass and copper. Aluminum and stainless steel are thin, lightweight and flexible, while still retaining the strength necessary to control the flow of liquid. Usually when a heavy metal like iron is used for the body of a valve, one of those two lighter metals is still used for the disc or plunger. Plastic is also used, particularly thermoplastics that are developed specifically to be used as valve material. Although they are not as resistant to corrosion as metal, they are cheaper. It’s all about options.

Hydraulic relief valves protect hydraulic systems from being exposed to high pressures that exceed the mechanism"s specified limits. A relief valve is placed at the entrance to a separate tube and is set to only open when a certain amount of pressure is applied, which can only be applied if there is too much liquid or gas in the chamber or pipe. An auxiliary passage, which is where the relief valve sends the extra liquid or gas to relieve the pressure in a mechanism, is usually just an extra pipe that leads to a chamber where most likely the fluid is burned and the gas left over is released into the atmosphere.

This is a particular necessity in the chemical and petrochemical manufacturing industry, as well as in petroleum refining plants, natural gas processing and power generation industries. If the pressure in a hydraulic pump exceeds its designed pressure limit, internal leakage or damage to the pump components can occur. Depending on what the liquid is, such leaks could also cause serious damage to individuals in the vicinity and the environment.

The purpose of the valve is to, when energized, provide a flow path for a flow of hydraulic fluid from its source to the hydraulic system. When de-energized, the valve blocks flow from the hydraulic energy source and vents the hydraulic system to tank.

Q: What is Control Reliablitiy?A: Control Reliability essentially states that the safety system be designed, constructed and installed such that the failure of a single component within the device or system should not prevent normal machine stopping action from taking place, but shall prevent a successive machine cycle from being initiated until the failure is corrected. To achieve “Control Reliability”, a device should feature both redundancy and fault detection.

A: A safety valve, as it pertains to fluid power, is a component that, when properly applied, can allow access to an otherwise hazardous area. This is achieved by isolating the hydraulic source away from the system and venting any residual system pressure, downstream from the valve, to tank.

A: During normal operation, the valve operates like a traditional 3-way. If either of the redundant elements malfunction, the safety PLC or safety relay, monitoring the state of the redundant switches, will command the valve to its safe condition.

A: The three different configurations of Control Reliable Safety Valves are 2-way for blocking applications, 3-way for block and bleed applications, and LOTO or Lockout/Tagout.

A: A relief valve is a device that limits the maximum pressure in a system. It does help to keep a system and its surrounding environment safe from catastrophic failures due to over-pressurization but it is not a true safety product. The safety valves that we refer to are redundantly monitored devices that meet the rigorous requirements of safety standards organizations such as ANSI and ISO.

Valve manufacturers today are able to inspect parts during assembly rather than after to produce near-perfect fluid pressure relief valves. The Promess Electro-Mechanical Assembly Press (EMAP) uses no pneumatics or hydraulics; instead, press motion is initiated by a servomotor and ball screw. A computer monitors the press ram’s position and pressing force, and accepts data from additional external sensors. To make the pressure relief valve, the EMAP is fitted with an attachment that pumps fluid through the valve at 1.2 liters/min while it is in the press.

Sensors provide information on fluid flow and pressure to the EMAP’s controller. While the valve is assembled, the system monitors the valve release pressure. The EMAP compensates for variations in the valve components that affect release pressure by compressing the spring inside the valve to increase its resistance. The EMAP presses the valve seat into the valve body until the target release pressure of 1,000 psi is reached.
