accumulator safety valve manufacturer

Hydraulic systems work under pressure. This pressure has to be carefully maintained to ensure the system works efficiently. Heat and other outside factors can influence the pressure inside the system. Accumulators are used to regulate the pressure by increasing or decreasing the amount of fluid available.

But, for any system to be safe, there needs to be a backup, in case the accumulator malfunctions or breaks. That’s what accumulator safety valves are for. Of course, they can also allow pressure release just because the pressure has got too high and the system can still function normally.

Accumulator safety valves fit into the circuit to release pressure when needed. This effectively protects the rest of the system. Without the accumulator safety valves, excess pressure would cause the components to fail, dramatically dropping the pressure, rendering the system useless.

The right accumulator safety valves will save you the cost of replacing all the components in your system simply because the pressure has got too high.

It should be noted that in most countries accumulator safety valves, or pressure relief valves are a legal requirement. SAIP S.R.L. understands the rules and regulations of different marketplaces around the globe. Choosing their products will ensure you comply with local regulations.

To ensure reliable operation, direct-operated pressure relief valves are used in most cases. These are - in contrast to the pilot-operated pressure relief valves - less sensitive to contamination and have lower leakage.

There are additional requirements that should be followed by the design of the pressure valve:Damping of the valve cone with a suitable degree of damping, while complying with the valve stability and reaction speed

As a well-known manufacturer of hydraulic valves, control blocks and complete hydraulic systems, ARGO-HYTOS extends its product portfolio to include the pressure relief valve SR1A-B2, which was generally designed for use in hydraulic accumulator circuits.

This is a direct-operated pressure relief valve in screw-in design 7 / 8-14UNF. The structure of a poppet valve ensures minimal leakage when the valve is closed. By optimizing the damping behavior, a very good valve dynamic could be achieved while maintaining a stable function. The maximum operating pressure is 420 bar, the maximum flow rate is 60 l/min. For a precise pressure setting, 7 valve pressure levels are at the customer’s disposal. The opening pressure can be adjusted in the respective pressure level range by an adjusting screw and secured with a lock nut. It is also possible to obtain the valve in preset condition (setting sealed).

With regard to the surface protection, the valve body and the adjustment screw are zinc-coated. The sleeve and the seat are protected by carbonitriding, which further optimizes the mechanical characteristics.

In order to be able to work in limited work spaces, the plastic cap was adjusted. The seals, either NBR or FKM enable the use of the valve at -30 °C up to +120 °C. The valve was certified by the TÜV Süd according to the application for hydraulic accumulator circuits.

The MHA accumulator safety block of the ASB series combines all necessary functions to secure a hydraulic accumulator (either bladder, membrane or piston-type accumulator).

In case of emergency the operation of the shut off valve separates the accumulator from the hydraulic circuit. Afterwards the accumulator can be drained to the tank by using the manual (or as an option electrical) relief valve. In addition the accumulator is secured by a PED-certified pressure relief valve.

The hydraulic accumulator safety block HSB-06 is used for the prescribed protection and relief of hydraulic systems with pressure accumulators.It is possible to have a nominal size 06 installation without piping work by vertically linking them with a mounting plate. It is easy to add other functions, such as (throttle) check valves, by using standard sandwich plates. The internal connection of channels A, B and P offers additional connectivity options, including but not limited to accumulator, consumer or testing connections.The directly operated pressure relief valve has achieved the type examination and can be supplied as pre-set.

According to the PED 97/23/EC, the increase in system pressure caused by the volume flow must not be greater than 10% of the setpoint response pressure (setpoint pressure). Attention! Due to the increasing volume flow, the system pressure increases by the level of counterpressure in the return line (connection “T”). Before ordering a valve with a type approval certificate it must be ensured that the maximum allowable flow (qVmax) of the safety valve at the desired response pressure p is greater than the maximum possible flow rate of the system to be protected. Please consult the diagram on the data sheet regarding the area of ​​application for the HSB-06. The specified maximum flow qVmax must not be exceeded. Discharge piping from safety valves must have a safe outlet.

The safety block allows for isolation of the accumulator for maintenance or system testing, and will function as an emergency shut-off device or pressure relief valve to protect the hydraulic system from over-pressurization or system failure.

A shutoff valve allows the accumulator to be removed from the hydraulic system by attaching it to safety blocks for hydraulic accumulator safety. Hydraulic accumulators can release the hydraulic fluid they contain under pressure as needed. They can also replace lost pressure if the pump fails or fluid is lost.

Shutoffs are used to protect, isolate and unload hydraulic systems. Function The accumulator shutoff block protects, isolates, and unloads hydraulic accumulations. An accumulator adapter connects the accumulator shutoff block and the accumulator. The pressure release valve protects the accumulator against excessive pressure. You must avoid any control actions on the pressure relief valve.

The maximum operating pressure must be significantly lower than the working pressure. The pressure relief valve protects the accumulator from excessive pressure. Use of the pressure relief valve for control purposes is not advised. The differential between the operating pressure and working pressure must be large enough. If at all possible, avoid using the pressure release valve.
