Logic Unit SRL 6-50
If the level electrode (high or low level limiter) is installed in an isolatable level pot outside the boiler, make sure that the level pot is drained and the connecting lines are rinsed at regular intervals. For this purpose the connecting lines must be shut off and opened at regular intervals and by opening and closing the drain valve the lines and the level pot will be rinsed. The logic unit is designed to be used in conjunction with level switch NRS 1-50 (water level limiter) or level switch NRS 1-51 (high level alarm) to monitor the correct timing and sequence of valve operations. During the rinsing process the level switch jumpers the level electrode, thus preventing the safety or control circuit from opening. The level switch - controlled by the logic unit - also monitors the rinsing and bypass time.

819743 Electropneumatic smart positioner SP500
The SP500 smart valve positioner is loop powered from a 4 - 20 mA input signal to provide accurate adaptive positional control of pneumatic actuated linear and quarter turn valves. Precise control is maintained through valve position feedback that automatically varies the pneumatic output pressure to overcome the effects of stem friction and flow forces to maintain desired valve position. Indication of valve position is provided through a continuous digital display of % travel.

Double Swing Check Valve BB 1 BB 2 BB 3
The equipment prevents the backflow of liquids or gases in pipes. The equipment can be installed in horizontal and vertical pipes. If the equipment is mounted in a vertical pipe the flow must normally be from bottom to top. If springs of type 5 VO are used, the equipment can also be installed in vertical pipes with downward flow. This kind of installation (vertically downward flow) is only possible with equipment up to DN 500.

Conductivity Controller LRR 1-52 Conductivity Controller LRR 1-53 Operating & Display Unit URB 50 LRR 1-52 LRR 1-53 URB 50
The functional unit consisting of the operating & display unit URB 50 / conductivity controller LRR 1-52, LRR 1-53 in conjunction with conductivity electrodes LRG 1.-.. and conductivity transmitter LRGT 1.-.. is used as conductivity controller and limiter, for instance in steam boilers, (pressurized) hot-water installations as well as condensate and feedwater tanks. The conductivity controller indicates when the preset MAX or MIN conductivity is reached, opens or closes a continuous blowdown valve and may also control an intermittent blowdown valve.

Panel Adaptor Large
The Panel Adaptor Large is designed for use with the large form factor SPECTORmodul controllers without rotary button (e.g. NRS 1-50, 1-51) and enables controller installation in a control cabinet door. It offers the advantage of status visibility and alarm testing without opening the cabinets door. The installed adaptor fulfi lls the protection class IP65.

SPECTORconnect safer, more efficient steam production
For the operator of a pressurized steam or hot-water plant, safety, reliability, availability and cost efficiency are the top priority. To an increasing extent, plant automation and visualisation are also growing in importance. In order to meet these stringent requirements, GESTRA AG has been making exclusive use of low-maintenance, non-wearing electrode systems for more than five decades now. These systems function entirely without moving parts, which mean long service lives and very low failure rates.

Steam Trap STERIline® SMK 22, SMK 22-51 suitable for clamp connections to DIN 32676, for pipes to DIN 11866 (DIN 11850, ISO 1127, ASME-BPE) PN 10
The thermostatic steam trap features a minimum stagnant area and corrosion-resistant thermostatic capsule with membrane regulator, which is unaffected by water hammer. Used for removing condensate and air venting steam in sterile and aseptic applications. The thermostatic capsule with membrane regulator and rolling ball features a self-centring ball stud that can move freely, ensuring a steam-tight seal that is unaffected by dirt particles.

Au démarrage de l’installation le purgeur est complètement ouvert. Les condensats froids et l’air sont évacués. Avec l’augmentation de la température les lames en acier Duo se dilatent et tirent la tuyère étagée dans le sens de la fermeture. Immédiatement en dessous de la température de saturation l’organe de fermeture est fermé. L’effect thermodynamique établie dans la chambre de la tuyère étagée produit une force agissant dans le sens de la fermeture.
Les clapets de retenue des types RK et RKE servent à empêcher le reflux des fluides dans les conduites. Seuls les clapets de retenue du type RKE peuvent être utilisés comme robinetterie finale (par ex. casse-vide). Ces appareils sont soumis à des contrôles et des marquages en conséquence et ne doivent pas être utilisés avec une fonction liée à la sécurité (par ex. soupape de sûreté). Les clapets de retenue RKE sont disponibles uniquement avec des obturateurs métalliques.
