Safety valvesGeneral information

0301

Safety valves are among the facilities that must prevent higher pressures from occurring in installations than they weredesigned for. Pressure protection is of such importance that it is covered by legislation. Apart from legislative (at Europeanlevel) regulations for pressure devices in general, users are also confronted with (national) regulations coveringcommissioning.

These include the following:

Country Legislation Inspection by Commissioning approval by Specification / StandardNetherlands PED 97/23/EG Notified Body Stoomwezen/Lloyd's Register Rules for pressure equipment A 1301, T 0103Germany PED 97/23/EG Notified Body VdTUV AD 2000-A2, TRD 421 / 721United States of America ASME I & VIII

Based on the opening characteristics, safety valves can be divided as follows:

Proportional-relief valvesThese valves open proportionally to the pressure increase. They are generally used in situations where limited blow-offcapacities are required and the loss of medium should be as low as possible (e.g. thermal expansion). Contrary to othervariants, proportional safety valves open very frequently. The overflow valve falls into the proportional safety valves segment.

Safety relief valvesThese valves are ideally suited for mid-sized quantities. The large proportional range ensures a smooth operation andprevention of pressure peaks, mainly applicable for liquids. They are applied in situations where the capacity of a proportionalvalve is no longer sufficient and for situations in which even the smallest high-lifting valve is still too large.

Full-lifting safety valvesThese valves open immediately, within a pressure increase of 5%, to the structural limitation of lifting height. They are mainlyused for safeguarding gases and vapour, and specifically in those areas where the maximum quantity of medium should bedischarged as rapidly as possible.

Terms related to safety valves

Set pressureThe pressure measured at the valve inlet at which a safety relief valve should commence to lift under service conditions.

A tolerance of T 3% (ISO4126) applies to the set pressure.

Relieving pressureThe relieving pressure is that at which the safety valve reaches its maximum capacity. This point depends on the openingcharacteristics of the safety valve and the medium. For gases and steam this is 5% above the set pressure for a high-liftingsafety valve and for liquids this is 10% above the set pressure for a relief and proportional-lifting safety valve.

Re-seat pressureThe pressure measured at the valve inlet at which the safety relief valve re-seats.

Back pressureThe back pressure is the pressure occurring on the discharge side of the safety valve. Back pressure could occur during theblow-off of a safety valve (built-up back pressure) and could be the result of a prevailing pressure at the discharge side of thesafety valve (superimposed back pressure). Back pressure can be constant or variable. Remark: when the back pressureexceeds 15% of the set pressure, this has a negative influence on the operation of the safety valve.A good solution for this is the installation of a stainless steel bellows. Consult our product specialists if this is the case.

Operating pressure (Normal operating pressure)The operating pressure is the maximum system pressure during normal operation.

PTFE lining and nozzleIn chemical installations, one can be confronted with critical media or operational conditions which require special attentionregarding construction and safety, e.g.:

• Highly corrosive media• Extremely toxic media• High back pressure

A number of variants have been developed for the applications named above:

• A safety valve with a PTFE nozzle in the inlet and a protective coating in the discharge section, with the expectation thatthe valve will seldom be used. The PTFE nozzle prevents product contamination and product adhesion. If a stainless steelbellows is installed, correct functioning at up to 50% back pressure is guaranteed.

• A safety valve of which the inlet and discharge side are fully lined with PTFE. The PTFE bellows is gas tight and backpressure compensating. Due to the smooth PTFE-surfaces (max. Rz 16 µm) product adhesion is prevented.

High temperature variantFor liquids with a temperature exceeding 400 °C, a high temperature variant is required to protect the mechanism and springagainst prohibitive temperature influence. The maximum inlet temperature is 550 °C.

Lift stopper Lift indicator Test gag

Lift stopperBy means of a set screw, the safety valve is adjusted to the quantity of medium to be blown off.

Lift indicatorA lift indicator is used to sense the operational condition. In the event of a safety valve, the opening can be detectedremotely.

Test gagA test gag makes it possible to block the safety valve when the installation is tested above the set pressure of the safety valve.

Drain plugThe drain plug ensures dewatering of the body, mainly for condensation on safeguards for steam installations.

Pneumatic controlMost safety valves can be provided with a "supplementary loading". This system comprises four components;

• Safety valve• Actuator• Control (pneumatic, electric/pneumatic)• Air distribution station

The extra loading enables the system pressure to increase up to just below the set pressure. The functional tightness of thesafety valve that is provided with one of these supplementary loadings is guaranteed by this (Anti-Simmer-Device). When theset pressure is reached, the extra loading will support the opening and closing phase, hence the system will more quicklyreturn to the original situation.

This system brings the following benefits:

• Seat remains medium-tight until opening• Shorter opening times• Shorter closing times• Precise lift ratio• Independent functioning under back pressure

Advantages as detailed above result in less product loss, and thereby to cost savings.

Change-over valveChange-over valves are installed for the event that shut-down of the installation is not feasible or desired, either due toproduction or economic reasons,. With change-over valves it is possible to switch between parallel safety valves, withoutinterrupting the process, so that maintenance can be carried out.

The design guarantees:

• Minimal pressure loss (3%-criteria)• Availability of full bore during switch-over• Stable blow-off of the safety valves

Safety valvesInstallation and operating instructions


2008

0301

Safety valves are high quality fittings which should be handled with great care.Penetration of dust should specifically be avoided. Heavy shocks also need to be avoided as these could damage disc andseat. Prior to transport, the lever of a weight-loaded safety valve is locked by means of a wooden wedge. The (pipe) sectionbefore the safety valve should be cleaned before installation.

The set-up of safety valves should be such that the valve is positioned horizontally. Tension in the pipes at the intake ordischarge side should under no circumstances be transferred to the safety valve. Provisions to absorb reactive forces duringblow-off are to be installed as well. Once installed, the safety valve should be absolutely stationary, irrespective of the appliedforces. The sketch shows an example of a proper set-up.

For high-lifting safety valves starting from DN 100, it is recommended to use supports

Installation example for the discharge of water condensate

In order to prevent a safety valve blowing-off prematurely, it is essential to ensure sufficient differential pressure between theset pressure and the operating pressure. Refer to the chart as under General information.

No condensate or medium may remain in the discharge of the safety valve or anywhere of importance to the operation of thesafety valve (at the spring, bellows, etc.), as this could influence the actuation. Draining should always be arranged throughthe discharge pipe, installed with a slope.

Once a safety valve is operational, it can happen that leakage takes place following blow-off. The enormous speed of thedischarged medium has then carried along dirt and or liquid particles, which could have damaged the valve or seat. Carefuldismantling, grinding of disc and seat and re-installation is generally the only solution. For spring-loaded safety valves, theadjusting screw should be turned out slowly after the lifting cap has been carefully removed; use penetrating oil if required.Note: under no conditions must the spindle be rotated as long as (spring) tension is applied. The nuts holding the bonnet,can then be loosened without any danger. Spindle and disc can now be removed from the safety valve, after which the discand seat can be inspected for damage, and polished if necessary. For re-assembly, follow the reverse procedure. Safetyvalves with an inspection seal, must be inspected and approved by the original approving institution, followingre-commissioning.
